I've been working on a project for a couple of weeks now using a W1010 and motor carrier. It's been going ok, I do notice the mkr series USB port is a bit flakey, sometimes tricky to upload as the port disappears but this has been the same for all SAMD type boards ive ever tried, anyway, now the board has a power led and the charge led continuously strobing. The reset switch does nothing, even with double press. No USB port is reported either.
I still have 5v and 3.3v present at the power pins.
Any ideas or is it toast!
