New CircuitPython Board - error trying to load BootLoader

by MrCoxall on Fri May 29, 2020 10:44 pm

I have designed and had a new CircuitPython board built.
(https://github.com/Mr-Coxall/PyCard-2020)
It follows the hardware design of the Trinket M0 and the PyRuler.
I have been following this guide (https://learn.adafruit.com/how-to-progr ... s?view=all) to flash the ATSAMD21.

As a test I walked through the steps with an ItsyBitsy M0 that I have.
I was able to connect using the J-Link, no problem.
(After I figured out it must be in boot mode to connect)

When I try with the board I made, I am getting the following error:
"Error connecting to device over SWD".

Anyone have any ideas?
