That version was from https://github.com/raspberrypi/openocd.git

I will try from https://git.code.sf.net/p/openocd/code

Same result. No time now, I will try to chase this in a couple hours.

CX seems to come from rp2040.cfg line 88

For now,

 > sudo openocd -d -f interface/cmsis-dap.cfg -f target/rp2040.cfg \
      -c "adapter speed 5000" -c "program $1 verify reset exit" \
      2>&1 | grep CX
