update to match the automatic recovery script
== Introduction ==
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 [[Lizard Embedded Linux Kit (LELK)|LELK]] hardware and software.
== Tool Preparation ==
* Download the [[mirror:lizard/recovery/lizard-recovery.zip archive |lizard-Recoveryrecovery.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 [[mirror:lizard|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
