I.MX processor, Yocto Linux, LED state during boot operation

_ZZ_ — Thu, 13 Jul 2023 15:46:22 GMT

Hi Everyone,

I have an I.MX custom board running Yocto Linux. The board has two RGB LEDs (in total 6 LEDs), all have been defined in the device tree, accessible from the /sys/class/leds/ and work well in terms of functionality.

my question is that How do I turn on all the LEDs while the board is boot up and reset operation? some say could be done somewhere in uboot source code though.

Thanks for any help,

Hello, I hope you are doing well.

I suggest you check the next link and take a look on "default-state" LED sub-node properties on device tree.

Best regards.

Jorge.
