No COM port connected. When I click “Program Flash Memory” (without debug) it tries to use regular Arduino programming via Com port and fails. Is there a way to configure flash programming directly with the JTAG? Thanks April 11, 2022 at 21:00 #32499 felixcollinsParticipant As a work around, just hit run (debug) F5. This programs the flash before debugging. You can then detach the debugger and reset your device.
