This just hangs:

$ sudo /bin/bash /usr/local/bin/load_rp2040.sh

+ openocd -f interface/raspberrypi-swd.cfg -f target/rp2040.cfg -c init -c 'reset halt' -c 'load_image /usr/local/bin/main.elf' -c 'resume 0x20000000' -c exit

A solution: use the linuxgpiod interface, ex: 

adapter driver linuxgpiod
adapter gpio swclk 25 -chip 4
adapter gpio swdio 24 -chip 4

with openocd 0.12.0 #464
