xDot failed to program BIN File

[Paul Jackson]

Hello, I seem to two xDot’s that now will not program with simple helloworld let allow Dot_Examples. I’m unsure what has happened but I get error message on dropping BIN file on device
error: The interface firmware FAILED to reset/halt the target MCU
I’ve tried to set the bootloader and interface application as per link here to no effect.

Not sure if I have to get a JLINK debugger out to reprogram something else but if you have a pointer to why this suddenly stopped working I would really appreciate it.
Regards

Hi Paul,

If your xDot is on the developer board, hold the reset button down and release it immediately after you drop the bin file.

Kind regards,
Leon
