8MIC-RPI-MX8 Push Button Documentation

[senordos]

Hi I'm currently working with the 8MIC-RPI-MX8 along with the evk, and android 9. I was able to complete the steps listed in the quickstart for the mic array, as shown here: https://www.nxp.com/docs/en/quick-reference-guide/IMX-8MIC-QSG.pdf

I wanted to know if there was a way to get information on how to listen to the buttons and toggle the leds?

Hi senordos

one can use below dts

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8mm-evk-8...

as one can see it is compatible  "gpio-leds"; "gpio-keys", so one can look at linux tutorials for

"gpio-leds"; "gpio-keys", like :  https://elinux.org/CI20_GPIO_LED_Blink_Tutorial

Best regards
