Introduction[edit | edit source]
This article describe how to recover a corrupted U-Boot image on Lizard NOR Flash using a Windows host machine.
In brief user needs to:
- configure Lizard SOM to boot over serial port instead of on board NOR flash
- download and prepare serial communication tools
- use those tools to download first stage bootloader and U-Boot over UART
- use this U-Boot to update NOR flash
This assume that you're using a standard LELK hardware and software.
Tool Preparation[edit | edit source]
- Download the lizard-recovery.zip archive and extract it on your Windows PC
- If needed, replace the u-boot.bin file with your custom binary or download the latest LELK binary from DAVE Embedded Systems mirror
- Open the command prompt and go inside the folder where you extracted the recovery file
- Launch the utility with the serial port number as the argument
C:\Users\Desktop\lizard-Recovery\lizard> .\uart-recovery.bat COM1
The tools is now waiting for the board to wakeup

Board Preparation[edit | edit source]
- Power off the board and set the dip switch
S2.2 ONto select serial boot - Connect UART2 to your host PC
- Turn on the board
Flashing the firmware[edit | edit source]
Once the board boot up, after a couple of seconds of delay, the recovery procedure will start.
The script is totally automated and, in case of success, this is the output:
