The first upload was successful, but UART ping was working but could not set any voltage or turn it on. Screen flashed when receiving ping, but everything seemed to be working until I reflashed the firmware via UART (which failed).

Now if I'm trying to reprogram via SWD erase (sometimes works) but -C opendps flash doesnt.

I'm using a Pi4 as SWD interface, which worked for other projects.

But screen is still off.
