Arduino M0 help

[Steve]

I'm trying to port a HAB application that was originally written for the Arduino M0 to the pi pico

I'd like to get the project working on a Arduino M0 first and then step by step move it to the pico environment (having failed miserably to do it in a single jump). 

The problem is they don't make the Arduino M0 board any more.

First Q: has anyone got an Arduino M0 board that I could buy/beg/borrow/steal

Failing that: I purchased a HW-819 board which looks very similar to the M0 and is “compatible” with the Arduino Zero – The Zero and M0 have the same processor and pinout.

Second Q: is there any way to fool the Arduino programming environment that the board is a M0 ? At the moment the environment recognizes the board as a Zero and programming it as an M0 (or M0 pro) fails.

What's the error/debug log?

Have you looked into using PlatformIO instead of Arduino IDE? It's much better (but more complicated) in general, but it still retains Arduino's hardware abstraction layer.

OK, so it looks like the programmer isn't responding. I would suspect that the Chinese manufacturers didn't burn the required bootloaders into the chip's memory. Fortunately, I think this can be fixed by having a physical programmer attached to the ISP header.

That being said, it could be that I'm entirely misdiagnosing the issue.

Thanks,

    The port come up as: COM6 (Arduino Zero (Native USB Port))

The board programs OK as: "Arduino Zero (Native USB Port)" - but fails with the following when programed as "Arduino M0"

and the same error if programmed as "Arduino M0 Pro (Narive USB Port)"

I'll look into PlatformIO - as I'm really not a fan of Arduino
