pyocd flash fails on FRDM-K66F #1532

Open JanneKiiskila opened 1 year ago

Flashing of a .bin-file (which fits just fine to memory) fails on FRDM-K66F.

At the same time, I can flash the device just fine via cp <bin-file> /media/$USER/FRDM-K66F && sync, so device is not in an abnormal state. Seeems pyocd can't get it to the right state for flashing.

FRDM-K66F has Daplink, details below.

Try adding -M attach to your command:

connection:
...
  -M MODE, --connect MODE
                        Select connect mode from one of (halt, pre-reset, under-reset, attach).

This could be related to the device being locked? I think I've noticed an issue recently with connecting to a locked device being troublesome. I've done some work on it, but haven't fixed it yet, and haven't had a chance to get back to it. I'll try to reproduce again when I have a chance, after the next release.
