The SDK version I use is ti-processor-sdk-linux-rt-am62xx-evm-08.06.00.42 and I am making my own hardware operation, and the gpio port is connected to a relay. Now I want to test whether the function is normal, but I find that the gpio port cannot be controlled.
Pin E18 uses address 0x1a0. In the device tree, this pin is being used by a PWM (muxmode 6). GPIOs use muxmode 7.
