using gpio-keys on ccimx8x-sbc-pro

Question

Hi guys,
I'm trying to get some keyboard events on my ccimx8x-sbc-pro, by using gpio.
I wish I have linux event <59> (corresponding to F1 touche) when I set GPIO05_IO09 to the ground.

To achieve this, i've added the following lines in ccimx8x-wb.dtsi, right after reg_rf_bt_en: regulator-som@6 propertie :


gpio-keys {
compatible = "gpio-keys";
autorepeat;
status = "okay";

f1 {
label = "F1Key";
linux,code = <59>;
gpios = <&gpio5 9 0>;
};
};

when I use my newly compiled dtb, I can't see the gpio-key propertie ...
1) I have set CONFIG_KEYBOARD_GPIO=y kernel option
2) I've tried to commment / uncomment SC_P_ENET0_REFCLK_125M_25M_LSIO_GPIO5_IO09 line in pinctrl_expansion: expansiongrp

Can anyone tell me what I'm missing ?

regards

do sysinfo and it will generate a file, download it to a PC and extract. Do you see CONFIG_KEYBOARD_GPIO=y
There?

I was loading the wrong dtb file in uboot...
someting, the env 'fdt_file' seems to be erased and I still don't know why.


In the end, I've been able to catch gpio-keys and I how my question helps anyone who is looking to achive the same !

Hi,
it was the 1st indication I gave in my question :
1) I have set CONFIG_KEYBOARD_GPIO=y kernel option

And I can confirm that sysinfo is OK with that.

yes, just wanted to make sure your changes are making it in to the final image. So you are all set now?
