Hi AM62P SDK Champ !

My customers are developing using the AM62P Android SDK, and would like guidance on how to control the GPIO Input/Output direction and value—both from the Device Tree and from the Application User Space.

We haven't been able to find this information in the SDK documentation.

1. Device Tree Configuration

2. Android User Space Control

Thanks.

Best Regards,

Jack

Hi,

for device tree part same as classic linux , device source was in 'common/arch/arm64/boot/dts/ti/'

for using this GPIO you should use libgpio and when you say application user space is it a service , HAL or Android application ?

you have a good documentation in Linux release doc : https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/11_01_05_03/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/GPIO.html
