Hi!

I’m trying to run the battery sample on my feather v5, but it just gives gibberish and then hangs. Through a lot of commenting out of stuff and adding printk everywhere, I believe the issue comes from ddp->adc = device_get_binding(iocp->label); on line 108 in battery.c, which looks like it’s just hanging forever. Any clues as to what I’m doing wrong?

Full output log:
