Using Tera Term (or equivalent application), connect to the target board with the following settings:

Serial Port Configuration Settings

After powering up the board, you should see the Log-in prompt (refer to Figure 1).

Cycle power on the target board and interrupt the normal boot-up sequence by hitting the <Enter> key. You need to hit the <Enter> key within 2 seconds in order to interrupt the boot-up cycle before it boots from SATA.

If you successfully interrupt the normal boot-up sequence (refer to Figure 2), you will see the UBoot prompt. Otherwise cycle power and try again.

At the UBoot prompt, force booting from QSPI with the following command: 1. Type “run qspi_boot” Once Linux boots up, verify you can log-in to the target (refer to Figure 3). The default username is “root” and the default password for this username is “root”. Verify no files in root directory (refer to Figure 3) with the following commands: 1. Type “pwd” 2. Type “ls”

Verify that you can communicate to the target via Ethernet (refer to Figure 4). The default IP address and Subnet mask is 192.168.1.16 and 255.255.255.0 respectively.

The SATA write-protect can be disabled by grounding the write-protect pin, or by the following commands (refer to Figure 5): 1. Type “memtool -32 43c10094=0” (0 will Disable Write-Protect) 2. Type “memtool -32 43c10094 1” (1 will retrieve the Write-Protect Value)

Using WinSCP (or equivalent application), connect to the board (refer to Figure 6), and transfer the BSP image file from the host PC to the board (refer to Figure 7). Note WinSCP will copy the file to the /var/ftp directory on the target.

Run the following commands to re-format SATA and install the BSP image (refer to Figure 8): 1. Type “cd /var/ftp” 2. Type “ls” 3. nai_format_sata_drive.sh ROOTFS_XIL_NIU1A_VERSION_INFO_ext3.img

Cycle power on the target board and allow it to boot from SATA (i.e., do not interrupt boot-up sequence).
