Failed to launch GDB: Error erasing flash with vFlashErase packet (from target-download)
In the schematic you'll notice there is an error where `BOOT1` is misidentified, however we have pulled the correct `BOOT1` low (pin 37) manually with a jump wire, this did not change the output.
We have a working firmware for a different design that uses the same MCU so we don't beleive this to be a firmware issue per se.
Digging deeper the MCU believes the flash is protected and the device is locked, unlocking and clearing the flash appears to work, but subsequent attpempts to write to the flash fail with the same error:
<div>

I would appreciate it if somebody could reach out and asssist with this issue.
Mant thanks.
