Hi,

I used a watchdog chip named SGM706 on my customized board, which needs to be feed within 1.6s after power on.
It seems that only during CBOOT can the connected GPIO02(Q, 3) be set to feed dogs.

Is the above idea feasible? Or is there any other possible way?

hello 295839633,

you may access cboot sources via download center, please also refer to below APIs for GPIO controls in cboot.
for example,
$L4T_Sources/r32.4.2/Linux_for_Tegra/source/public/cboot/bootloader/partner/t18x/cboot/platform/tegra_shared/include/gpio.h
