I want to modify low level code (ie. ATF, LK, etc…)
When I overwrite wrong ATF, LK image to eMMC.
then it is impossible to recovery with good image (as I know).
Q1) Is there any method to fully recovery eMMC when even if linux booting failed?
Q2) Any method to boot ATF, LK, linux, … from SD slot?
If it is impossible by software, any other method by modifing hareware?
Q3) If “USB HOST SET” switch is on, any other boot method is supported from windows host?
