Tool/software:
Hello,
I have the soc "AM62P" on my custom board, where I configured some gpio pin "gpio1_2" to report the state of a push button, when pushed 0v and when not it should be 1,8v.
As you can see the mentioned pb is connected to D19, which i configuered as input in the pmx node of the uboot device tree.
main_powerbutton_pins_default: main_powerbutton_pins_default {
pinctrl-single,pins = <
AM62PX_IOPAD(0x0180, PIN_INPUT, 7) /* (D19) RGMII2_RXC.GPIO1_2 */
>;
};I am not able to see the state change at the gpio pin and I am not 100% sure which pin to target in uboot?
I assume, it should map to "gpio@601000_2", however LLM suppose it should be "gpio@600000_34", as the gpios are split into 32-pin banks.
