GPIO, SPI and PWM not working on Jetson Xavier NX

hello Out_of_the_BOTS,

it looks like a bug, we’ve follow the gpio calculation of PQ.06, but the sysnode report PV.03 here.
we need to obtain correct gpio number, is the GPIO allocation range change for every reboot cycle?

it’ll be public release around Q3/2022.

The GPIO allocation stays the same after each reboot.

gpiochip2: GPIOs 305-334, parent: platform/c2f0000.gpio, tegra194-gpio-aon:

hello Out_of_the_BOTS,

it turns out GPIO calculation as shown in comment #18 is not valid anymore for K5.10.
please refer to developer guide, To check a GPIO number, please follow the GPIO debugfs for looking up the port and offset. i.e. # cat /sys/kernel/debug/gpio | grep PQ.06

Seed studios has requested that I send them back the unit as it could be a hardware problem as Jetpack 4.6 had the same problem.

Once I get the unit back again we will see if we can the GPIO working.
