SK-TDA4VM: 40 pin rpi header in SK-TDA4VM

Manu Varghese

Part Number: SK-TDA4VM

How to access the GPIO of the 40 pin rpi header in SK-TDA4VM?
I tried with the ti-gpio-py sample code simple_out.py.
I cant see any toggles in the pins.

Is there any steps i am missing?

Hi Manu,

Can you confirm the device tree overlay is applied? Instructions for applying the overlay can be found here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/09_01_00/exports/edgeai-docs/devices/TDA4VM/linux/pi_hdr_programming.html
