Blink LED example AD9364-7020 with ADRV1CRR-BOB

Category: Software

HI all,

I'm using AD9361-7020 with ADRV1CRR-BOB and latest Kuiper Linux image. RF part with given setup works perfectly.

For my project i need to toogle one GPIO pin or LED from python or terminal. 

at /sys/class/leds I see 4 leds. If I change brightness from 0 to 255 nothing happens. Led pins at P2-4, P13 3 and 4 , P7-16 stays equal to zero.

What i'm doing wrong?

I use these descriptions/schematics
