WM1302 not working

Hello, this is my first time using WM1302, and I encountered this problem.

I followed the steps from this link: WM1302 Module Setup Guide

When I try to run ../lora_pkt_fwd -c global_conf.json.sx1250.US915, this is the output I get.

I think it about pin i using but i don’t know how to fix that

Thank you

Hi there,
Looks like it’s naging about that i see and not creating the DIR’s for GPIO’s.
What hardware you using? Can you show a Picturre?

You are close, you’ll get it. can you post config file?

Thank you for the reply
I am using a Raspberry Pi 4B.

My problem is related to GPIO, as I can’t create or access directories for it.

Upon further research, I discovered that Raspberry Pi OS Debian 12 (Bookworm) no longer includes sys/class/gpio (reference: Stop using /sys/class/gpio – it’s deprecated – The Good Penguin). Therefore, I need to switch to Raspberry Pi OS Debian 11 (Bullseye) to resolve this issue.

It’s okay now, I am so very thankful for you time.
