Original question:
Hi,
I would like to test GPIO pins output and input for sk-AM62 EVM by connecting to either external or internal LEDs(if any).
I tried using echo 244>/sys/class/gpio/export but nothing happened.
Currently MCU_GPIO0_2 is connected to the LED.
Thanks in advance.
Yes I have added the GPIO pinmux in the device tree.

Yes, you need to set the PINMUX for the GPIO pins you needed in the kernel device tree file. Otherwise, the pins won't work in GPIO mode.
You can refer to "usr_led_pins_default" in k3-am62x-sk-common.dtsi to understand how GPIO1_49 PINMUX is configured and used in "leds" DT node. The PINMUX configuration itself can be generated using Sysconfig tool (recommended) or manually by referring to the device Datesheet.
You mean I need to configure more than just following?
I followed the "usr_led_pins_default". I tried Sysconfig tool but I don't know how to include the .syscfg file when I build the dtb files as I am not using CCS.

};Hi Cyra,
You mean I need to configure more than just following?
No. You are almost there.
You need to copy the pinmux data (devicetree.dtsi) you got from Sysconfig tool into the section "&main_pmx0". You can refer to how "usr_led_pins_default" sits in the same section in the board device tree file.
Please note that the line 5 misses '}' in the pinmux setting you posted above. I guess it is just a copy&paste error. Sysconfig should generate the correct format.
i have added the main_pmx0 to device tree file. But still not working. I have attached the k3-am62x-custom.dts file and k3-am62x-sk-common.dtsi file.
Please let me me know whether i am doing anything wrong.

I don't understand your patches.
The first file you attached is a patch to file k3-am62x-sk-common.dtsi, but the patch removes usr_led_pins_test pinmux. Is it supposed to add a pinmux for the GPIO pin you are going to use?
The first patch removes pinmux setting for gpio0_2, while the second file, which defines the led-1 node, specifies gpio0_21. Which GPIO pin do you use?
Hi,
I am using the pin number 13 of user expansion connector.
Below is the patch format of k2-am62x-sk-common.dtsi. I combined the previous two files (k3-am62x-custom.dts file and k3-am62x-sk-common.dtsi) into this k3-am62x-custom.dtsi.
I also attached the gpioinfo result.

The user expansion connector pin 13 is GPIO0_42, but
> gpios = <&exp1 44 GPIO_ACTIVE_HIGH>;
Where does this "exp1 44" come from?
I think it should be "gpio0 42" to match the gpio pin name you set in the pinmux, isn't it?
Have you tried the instructions in the link below to manipulate the GPIO and the LED?
Have you probed the GPIO pin if it is high as intended?
