Hi,
First time customizing u-boot, forgive my basic question.
To implement a factory reset, my initramfs expects a ‘factoryreset’ kernel
parameter to format an overlay FS partition before mounting it.
The target machine is a Tegra TX2.
I’m able to use the Volume Up button for factory reset, which is gpio-313 .
When starting the board if I press the button say 5s, I’d like to add the
‘factoryreset’ parameter to the boot parameters
I think I could use this syntax @uboot_var('factoryreset') in the
KERNEL_ROOTSPEC variable and have the variable set either to '' or
'factoryreset'
Maybe, I should append distro_bootcmd to add the gpio pin reading to
set factoryreset variable before proceeding with the boot sequence.
But how can I add the variable and have it set if the if the gpio pin is at
a certain state?
Thanks,
-Damien
