SK-AM62A-LP: The gpioset could not use in sdk 10.01

Hello,

What device tree changes have you made for the GPIO?

You can follow a Thread like this: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1268671/sk-am62-using-the-gpios-in-the-40-pin-user-expansion-port/4804378

Just note that this is for AM62x not AM62A.

I add some gpio config in dts. This change worked well when I use the sdk9.2, but in sdk 10.01 I found I could use gpioset in userspace.
Thanks!

Hello,

There is a change in libgpiod library (not TI Code) that was included in SDK 10.0+. You can either name the GPIO in the device tree and call the name or add a --unquoted parameter to the command.

Option 1:

Change the device tree to include line names. See below for an example.

&main_pmx0 {
    pinctrl-single,pins = <
        AM62X_IOPAD(0x009c, PIN_INPUT, 7) /* (V25) GPMC0_WAIT1.GPIO0_38 */
    >;
};

&main_gpio0 {
    status = "okay";
    pinctrl-names = "default";
    pinctrl-0 = <&main_gpio0_pins_default>;
    gpio-line-names ="","","","","","","","","","", //GPIO0_0->9
                    "","","","","","","","","","", //GPIO0_10->19
                    "","","","","","","","","","", //GPIO0_20->29
                    "","","","","","","","","TEST_GPIO",""; //GPIO0_30->39
};

Use 'gpioset TEST_GPIO=1' or 0.

Option 2:

Don't change the device tree and use 'gpioset --unquoted -c 1 7=1' or 0.
