The above U-Boot log is an example log; the actual U-Boot log may vary slightly depending on the BSP version
available on the board.
By default, the FRWY-LS1046A comes preloaded with BSP composite firmware image. You can deploy Ubuntu
userland on the board, but due to limited NOR flash memory (64 MB), you need to use an external memory device,
such as a micro-SD card or USB mass storage device for storing the BSP images.
For steps to download and assemble updated BSP images and then to deploy BSP Ubuntu distribution on the
FRWY-LS1046A board, see Layerscape FRWY-LS1046A BSP User Guide.

11 Troubleshooting

This section explains the basic troubleshooting tips for the FRWY-LS1046A.
Console not showing any print
Perform the following steps in case console is not showing any print:
1. Ensure that USB-to-UART bridge VCP driver is installed correctly on the host computer.
2. Ensure that the DIP switch has default settings, it means, SW1[1:10] = 0010001000.
3. Ensure that the power adapter is connected properly to the board power jack and external power supply.
4. Ensure that the cable making console connection is properly connected as mentioned in

6. Press the reset button to reboot the board. The Tera Term console should display U-Boot log.
7. If boot log is still not showing on console, then the BSP image available in the NOR flash memory may be corrupt. In this
case, use CodeWarrior TAP to flash new images and recover the board. For details, see
Guide.
