SOFTWARE

Built-In Test

The 68INT6 supports options for Power-On-Self-Test (POST) testing (memory, peripherals, etc.). The 68INT6, when configured with an NAI XMC, also supports function modules with NAI’s flexible, leading-edge, fully programmable and continuous background built-in-test (BIT) enabled function. BIT tests on board functions and functions contained on NAI XMC-enabled expansion modules, making it a useful field service tool.

BIOS

The 68INT6 utilizes the Insyde Unified Extensible Firmware Interface (UEFI) BIOS. The BIOS provides for low level functions required by the processor core and chipset. The BIOS also controls many configuration options. The BIOS configuration controls many details concerning the behavior of the hardware from the moment power is applied. The user’s BIOS configuration options are saved in the Serial Peripheral Interface (SPI) Flash memory. Both the BIOS and BIOS configuration data is stored in the SPI Flash device. The SPI Flash is non-volatile, and the BIOS configuration settings are saved without system or battery power. There is no battery on the 68INT6. The BIOS supports several modes for booting, including remote booting from any of the Ethernet ports.

Operating System Support

The 68INT6 hardware supports the following operating systems:

  • Wind River Linux and HVP
  • VxWorks and VxWorks Cert Edition
  • Windows
  • Ubuntu 22.x Linux
  • DDC-I DEOS
  • Lynx MOSA.ic
  • Green Hills INTEGRITY-178 tuMP

Software Support

The ENAIBL Software Support Kit (SSK) is supplied with all system platform based board level products. This platform’s SSK contents include html format help documentation which defines board specific library functions and their respective parameter requirements. A board specific library and its source code is provided (module level ‘C’ and header files) to facilitate function implementation independent of user operating system (O/S). Portability files are provided to identify Board Support Package (BSP) dependent functions and help port code to other common system BSPs. With the use of the provided help documentation, these libraries are easily ported to any 32-bit O/S such as RTOS or Linux.

The latest version of a board specific SSK can be downloaded from our website www.naii.com in the software downloads section. A Quick-Start Software Manual is also available for download where the SSK contents are detailed, Quick-Start Instructions provided and GUI applications are described therein. For other operating system support, contact factory.

INITIAL SETUP

Backplane and Power Supply

The 68INT6 requires up to 30 Watts steady state from the power supply, with sufficient margin to accommodate any additional inrush current. The PCI power supply must be capable of 2.5 A @ 12 V rail and 100 mA @ 3.3_Aux V.

Keyboard and Mouse

Depending on how the 68INT6 was configured at the factory, a keyboard and mouse may be required to set your BIOS configuration options. A mouse and keyboard can be connected to the 68INT6 for initial system setup.

Video Monitor

Refer to the 68INT6 ordering code for the video configuration option (See Part Number Designation section in this manual). Only DisplayPort is natively supported and may be used for the initial setup. Any other interface must utilize a converter from DisplayPort (some of these also require a BIOS menu setting to be changed). Note that the Video output is configured as rear I/O.

POST

Each time the 68INT6 boots, it must pass the BIOS Power-On-Self-Test (POST), which is summarized below.

  1. Tests the Power Supply to ensure that it is turned on and that it releases its reset signal.
  2. CPU must exit the reset status mode and thereafter can execute instructions.
  3. UEFI Firmware is readable.
  4. UEFI Firmware checksum must be valid, meaning that it must be readable.
  5. CPU must be able to read all forms of memory such as the memory controller and memory bus.
  6. I/O bus / controller must be accessible. If the computer does not pass any of the above tests, the board will fail the POST.

Operating Frequency

Using Intel® Speed Shift Technology*, the operating frequency will toggle from a maximum value (set in the BIOS) down to 800 MHz depending on the workload and temperature. The temperature at which the processor will start to throttle is 95°C.

*Intel® Speed Shift Technology is an energy-efficient method of frequency control by the hardware rather than relying on OS control. Processor decision is based on the different system constraints (ex. workload demand, thermal limits) while taking into consideration the minimum and maximum levels and activity window of performance requested by the Operating System.

The maximum operating frequency value can be set in the BIOS via the ‘Advanced >> CPU Configuration >> CPU Flex Ratio Setting’ menu.

  • The default setting is [28], which corresponds to a maximum value of 2.8 GHz.

  • The minimum setting is [8] which corresponds to a value of 800 MHz.

Note

‘Advanced >> CPU Configuration >> CPU Flex Ratio Override’ MUST be set to Enabled to change the ‘CPU Flex Ratio Setting’.

TTL Registers

Attached to Intel® PCH-LP via local bus is a portion of the FPGA. This logic provides miscellaneous “glue” functions and 4 programmable TTL I/O channels (TTL_CH [4:1]). These TTL channels may be programmed as inputs or outputs as needed. Channels that are programmed as inputs may generate interrupts. Interrupts on input pins can be programmed to occur on (high to low) or (low to high) input pin transitions.

The 68INT6 utilizes level shifting single ended bus transceivers, allowing the I/O pins to be 5 V tolerant. Each I/O pin is individually pulled up on card by a 4.7 KΩ resistor to the internal 3.3 V supply rail. External pull ups are not required for open collector operation. The TTL_CH [4:1] signals are pinned out as rear I/O on connectors P1 and P2. As a factory option, the TTL_CH[2] pin may be disconnected and its associated P2 pin used to support a Tamper Detect Interface and Action Circuit.

TTL Direction
Function:TTL direction. Sets channels as inputs or outputs. Bitmapped per TTL channel.
Function Address Offset(s):0x14
Type:binary word (16-bit)
Read/Write:R/W
Initialized Value:0x0000
Operational Settings:Write 0 for input; 1 for output: Default is configured for Input. Data bits [3:0] correspond to one of four channels TTL_CH [4:1] respectively.

TTL Data
Function:Reads the TTL state of a specific channel’s I/O pin. When configured as an output, write to this register to set the channel to drive high or low. Bitmapped per TTL channel.
Function Address Offset(s):0x18
Type:binary word (16-bit)
Read/Write:R/W
Initialized Value:0x0000
Operational Settings:When TTL_DIR register has channel configured as an input (0), read corresponding bit for the state of the TTL input. When TTL_DIR has channel configured as an output (1), write 0 for Low output/write 1 for High output: Data bits [3:0] correspond to one of four
channels TTL_CH [4:1] respectively.

Note

Reading this register returns the output to the I/O pin of a specific channel and does not return the value set to the register. Because of this, if there is impedance to the pin it may not return the proper setting. For example, if the channel is set to drive high and some impedance causes it to drive low, then this register will read low (0). To guarantee the correct setting is read, please refer to the TTL Loopback register.

Function Address Offset(s):0x1C
Type:binary word (16-bit)
Read/Write:R
Initialized Value:0x0000
Operational Settings:Reads the state of output register for each channel, regardless of the state of the I/O channel.

Note

This provides the last commanded/written output value, which may differ from the TTL Data ‘read’ status (if there is a problem, can be used for BIT status).

TTL IRQ Status
Function:When an interrupt for a channel or channels occurs, the corresponding bit for that channel will be set High in this register. Bitmapped per TTL channel.
Function Address Offset(s):0x28
Type:binary word (16-bit)
Read/Write:R/W
Initialized Value:0x0000
Operational Settings:When a TTL input channel generates an interrupt, the corresponding bit in the TTL_IRQ_STAT is set High (1). Once a bit
is set by a transition on the input pin, the bit remains set until cleared by a register write. Writing a (1) to the corresponding bit resets the interrupt
status to (0).

68INT6 PART NUMBER DESIGNATION

Click here for the 68INT6 part number designation

APPENDIX: NAI-XMC CONFIGURATION OPTION

When configured with the optional NAI-XMC mezzanine site, the 68INT6 can support up to two independent, smart function modules based on NAI’s COSA® architecture. With over 100 modules to choose from, this option further expands the SBC’s capabilities beyond the standard XMC site, providing a perfect solution for SOSA™-aligned rugged commercial, industrial, and aerospace applications.

Register Memory Map Addressing

The register map address consists of the following:

• cPCI/PCIe BAR or Base Address for the Board • Module Slot Base Address • Function Offset Address

Board Base Address

The table below lists the BAR used for access to the motherboard and module registers. The second BAR is used internally for motherboard and module firmware updates. The other cPCI/PCIe BARs not listed are not used.

NAI BoardsDevice IDBusMotherboard and Module Register AccessMotherboard and Module Firmware Updates
Controller/Master Boards
68INT6N/APCIeBAR 1 Size: Module Dependent (minimum 64K bytes)BAR 2 Size: 1M bytes

Module Slot and Function Addresses

The memory map for the modules are dependent on the types of modules on the board and the order in which the modules are installed on the board as well as the firmware installed on the motherboard. The function modules are enumerated allowing for dynamic memory space allocation and therefore the “start” address of the module function register area is factory pre-defined (and read from) the Module Address register. Refer to Figure 1 for an example.

Figure 1. Register Memory Map Addressing for Motherboards with 2 Modules

Address Calculation

Motherboard Registers:

Read/Write access to the motherboard registers starts with the base address for the board and then the motherboard base offset address.

For example, to address Module Slot 1 Start Address register (i.e. register address = 0x0400):

  1. Start with the base address for the board.
  2. Add the motherboard base register address offset.
Motherboard Address =Base Address
Motherboard Address Offset		= 0x0000 0400
0x0000 0000 + 0x0400

Module Registers:

Read/Write access to the Function module’s registers start with the base address of the board. Add the “content” for the Module Start Address and then, add the specific module function register offset.

For example, to address an appropriate/specific function module with a register offset:

  1. Start with the base address for the board.
  2. Add the value (contents) from the module base address offset register (contents/value of Motherboard Memory register for Module 1 (i.e., @ 0x0400) = 0x4000.
  3. Then add the specific module function Register Offset of interest (i.e., A/D Reading Ch 1 @ 0x1000)
(Function Specific) Address =Base Address +Module Base Address Offset +Function Register Offset= 0x0000 5000
0x0000 00000x40000x1000

Motherboard Sensor Registers

The registers listed in this section apply to each module sensor listed for the Motherboard Sensor Summary Status register. Each individual sensor register provides a group of registers for monitoring motherboard temperatures readings. From these registers, a user can read the current temperature of the sensor in addition to the minimum and maximum temperature readings since power-up. Upper and lower critical/warning temperature thresholds can be set and monitored from these registers. When a programmed temperature threshold is crossed, the Sensor Threshold Status register will set the corresponding bit for that threshold. The figure below shows the functionality of this group of registers when accessing the Zynq Core Temperature sensor as an example.

Interrupt Vector and Steering

When interrupts are enabled, the interrupt vector associated with the specific interrupt can be programmed (typically with a unique number/identifier) such that it can be utilized in the Interrupt Service Routine (ISR) to identify the type of interrupt. When an interrupt occurs, the contents of the Interrupt Vector registers is reported as part of the interrupt mechanism.

In addition to specifying the interrupt vector, the interrupt can be directed (“steered”) to the native bus or to the application running on the onboard ARM processor.

Note

The Interrupt Vector and Interrupt Steering registers are mapped to the Motherboard Common Memory and these registers are associated with the Module Slot position (refer to Function Register Map).

Function:Provides the ability to command individual Modules to Reset, Power-down, or Power-up.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0xFFFF FFFF
Read/Write:R/W
Operational Settings:The Module Control Commands registers provide the ability to request individual Modules to perform one of the following
functions - Reset, Power-down, Power-up. Only one command can be requested at a time per Module. For example, one can’t request a Reset
and a Power-down at the same time for the same Module. Once the command is recognized and handled, the bit will be cleared.

Note

Clearing of the command request bit only indicates the command has been recognized and initiated, it does not indicate that the command action has been completed.

There is one Control Command Request register per Module. Each register is Bit-mapped as shown in the table below:

Bit(s)Description
D31:D3Reserved
D2Module Power-up
D1Module Power-down
D0Module Reset

Module Health Monitoring Registers

Module Communications Status
Function:Provides the ability to monitor factors may effect communication status of a Module.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0xFFFF FFFF
Read/Write:R
Operational Settings:The Module Communications registers provide the ability to monitor factors that may effect the Communications Status of
individual Modules. There is one register per Module. Each communication factor is bit mapped to the register as shown in the table below:
Bit(s)Description
D31:D5Reserved
D4Module Communications Error Detected
D3Module Firmware Not Ready
D2Module LinkInit Not Done
D1Module Not Detected
D0Module Powered-down

Module Powered-down: The user can request an individual Module be powered-down (see Module Control Command Requests). Once the request is detected and acted upon, this bit will be set. Once powered-down, you will not be able to communicate with the Module.

Module Not Detected: If a Module in this slot has not been detected, you will not be able to communicate with the Module.

Module LinkInit Not Done: Module communications is accomplished via SERDES. LinkInit is required to establish a connection to the Module. If the LinkInit has not been successfully completed, you will not be able to communicate with the Module.

Module Firmware Not Ready: Each Module has Firmware that is ready from Module QSPI and loaded for execution. If this Firmware was not loaded and started successfully, you may not be able to communicate with the Module.

Module Communications Error Detected: If at some point during run-time, communications with the Module has failed, this bit will be set.

Module BIT Status
Function:Provides the ability to monitor the individual Module BIT results from all configured modules. both the Current BIT status and the Latched BIT status for each module can be read from this register. When a latched status bit is set, it will remain so until the next power cycle or board reset. The affected module registers can be queried for additional information as to the nature of the BIT failure.
Type:unsigned binary word (32-bit)
Data Range:0x0000 0000 to 0xFFFF FFFF

Ethernet

(For detailed supplement, please visit the NAI web-site specific product page and refer to: Ethernet Interface for Generation 5 SBC and Embedded IO Boards Specification)

The Ethernet Interface Option allows communications and control access to all function modules either via the system BUS or Ethernet ports 1 or 2.

Ethernet 1Ethernet 2
The default IP address:192.168.1.16192.168.2.16
The default subnet:255.255.255.0255.255.255.0
The default gateway:192.168.1.1192.168.2.1

Note

Actual “as shipped” card Ethernet default IP addresses may vary based upon final ATP configuration(s).) Ethernet Port IP addresses may be field re-flashed to new default programmed addressed via use of the “IP Configuring for Ethernet Supported Boards” FLASH software support kit, available/documented from the specific product web page.

The NAI interface supports IPv4 and IPv6 and both the TCP and UDP protocols. The Ethernet Operation Mode Command Listener application running on the motherboard host processor implements the operation interface. The listener is operational on startup through the nai_MBStartup process and listen on specific ports for commands to process. The default ports are listed below:

  • TCP1 - Port 52801
  • TCP2 - Port 52802
  • UDP1 - Port 52801
  • UDP2 - Port 52802

Ethernet Message Framework

The interface uses a specific message framework for all commands and responses. All messages begin with a Preamble code and end with a Postamble code. The message framework is shown below.

Preamble
2 bytes Always 0xD30F
SequenceNo
2 bytes
Type Code
2 byte
Message Length
(2 bytes)
Payload
(0..1414 bytes)
Postamble
2 bytes Always 0xF03D

Message Elements

PreambleThe Preamble is used to delineate the beginning of a message frame.
The Preamble is always 0xD30F.
SequenceNoThe SequenceNo is used to associate Commands with Responses.
Type CodeType Codes are used to define the type of Command or Response the message contains.
Message LengthThe Message Length is the number of bytes in the complete message frame starting with and including the
Preamble and ending with and including the Postamble.
PayloadThe Payload contains the unique data that makes up the command or response.
Payloads vary based on command type.
PostambleThe Postamble is use to delineate the end of a message frame.
The Postamble is always 0xF03D.

Notes

  1. The messaging protocol applies only to card products.
  2. Messaging is managed by the connected (client) computer. The client computer will send a single message and wait for a reply from the card. Multiple cards may be managed from a single computer, subject to channel and computer capacity.

Board Addressing

The interface provides two main addressing areas: Onboard and Off-board.

Onboard addressing refers to accessing resources located on the board that is implementing the operation interface (including its modules).

Off-board addressing refers to accessing resources located on another board reachable via VME, PCI, or other bus. Off-board addressing requires a Master/Slave configuration.

The user must always specify if a particular address is Onboard or Off-board. See the command descriptions for the onboard and off-board flags.

Within a particular board (Onboard or Off-board), the address space is broken up into two areas: Motherboard Common Address Space and Module Address Space. All addresses are 32-bit.

Motherboard Common Address Space starts at 0x00000000 and ends at 0x00004000. This is a 4Kx32-bit address space (16 kbytes).

Module Address Space starts at 0x00004000. Module addressing is dynamically configured at startup. NAI boards support between 1 and 6 modules. The minimum module address space size is 4Kx32 (16 kbytes) and module sizes are always a multiple of 4Kx32.

Module addressing is dynamic and cumulative. The first detected module (starting with Slot 1) is given an address of 0x00004000. The 2nd detected Module is given an address of:

First_Detected_Module_Address + First_Detected_Module_Size

Note

Slots do not define addresses.

If no module is detected in a module slot, that slot is not given an address. Therefore, if the first detected Module is in Slot 2, then that module address will be 0x00004000. If the next detected module is in Slot 4, then the address of that Module will be:

Second_Detected_Module_Address = First_Detected_Module_Address + First_Detected_Module_Size

If a 3rd Module is detected in Slot 6, then the address of that Module will be:

Third_Detected_Module_Address = Second_Detected_Module_Address + Second_Detected_Module_Size

Note

Module addresses are calculated at each board startup when the modules are detected. Therefore, if a module should fail to be detected due to malfunction or because it was removed from the motherboard, the addresses of the modules that follow it in the slot sequence will be altered. This is important to note when programming to this interface.

Users can always retrieve the Module Addresses, Module Sizes and Module IDs from the fixed Motherboard Common address area. This data is set upon each board startup. While the Module Addressing is dynamic, the address where these addresses are stored is fixed. For example, to find the startup address of the module location in Slot 3, refer to the MB Common Address 0x00000408 from the Motherboard Common Addresses table that follows.
