# U-Boot bootscript for altbootcmd (dual boot fallback after retries)

|

# for a number of tries. If the limit is reached, altbootcmd is run instead.

# This is the script that it will run. It has to:
|
|
# * switch back to previous system
|
|
# * reset the firmware update flag
|
|
# * run the regular boot command
