User board LED on i.MX 6SX

[mmmtq2011]

Hi,

I'm new at NXP, I just received the i.MX 6SX, and I've been looking at the schematics to check if there are any user LEDs on the board, because I want to test a program that blinks the LED when I press the function pushbuttons, but it looks that they are no any accessible LEDs on the board. 

I've checked the linux sysfs and I've found three mmc LEDs inside this path: /sys/class/leds/ but when I toggled any of them none of the LEDs on the board are toggled. 

so my question is: is there any user LED on i.MX 6SX board?

Best Regards,

Mohammed

Hello Mohammed,

There are no user LEDs which can be used trough GPIOs on the i.MX6SX SABRE board (I’m assuming this is the board you have received from NXP but please double check that this is the case). You may find the schematics on the web to see how the LEDs are routed but I’m afraid it wasn’t designed with this feature in mind.

My apologies for the inconvenience.
Regards,
