Metro Express R0 Unsupported processor

by heater on Wed Jan 30, 2019 9:31 pm

I have recently purchased a Metro R0 Express and have followed these instructions to setup the Arduino IDE, get the proper libraries, boards, etc. installed.

I have followed the OSX and Windows instructions for setup, and both have resulted in the same issue.

When attempting to flash the Blink example I get the following error message from Windows (though OSX is very similar):
Code: Select all | TOGGLE FULL SIZE
Set binary mode
No device found on COM3
Send auto-baud
Set binary mode
readWord(addr=0)=0x30303077
readWord(addr=0xe000ed00)=0x30303030
readWord(addr=0x400e0740)=0x23342c30
version()=wE000ED00,4#w400E0740,4#V#
chipId=0x23342c30
Unsupported processor
An error occurred while uploading the sketch


On OSX I have installed and reinstalled both the FTDI drivers, and the Silicon Labs CP210x drivers (including legacy) multiple times.

Lastly, I have tried three separate cables, and nothing has been successful. I have used an official Arduino Uno in the past, and don't recall it being quite this difficult to flash.

Any help or recommendations would be greatly appreciated.

Edit: replaced the instructions link with correct url

Hi, heater!

That's great that you got the Arduino IDE installed.

Out of the box, however, it doesn't know about newer boards, including the Adafruit METRO M0 Express. If you scroll down the product page, you'll usually find a link to a guide on getting started with that particular product.

Inside the guide for your product you'll find Arduino IDE Setup. Follow those steps, and proceed to Using with Arduino IDE.

Try those, and come back here if you need more tips.

Cheers,

Eric

Thanks for the reply, my apologies, I linked the incorrect setup. I did actually follow the setup instructions that you have linked (I will edit my previous post to reflect this)

In the Arduino IDE I have installed
    - Arduino SAMD
    - Adafruit SAMD
    - Added the Adafruit package for additional boards

I have also installed the Windows 7 Adafruit drivers on windows,

Before flashing I had selected the Adafruit Metro M0 Express board

With the COM3 port selected (in windows 7). The port on OSX was much different, but since the issue is happening on both systems, just getting it to work on windows is sufficient.

Does the board actually appear on COM3 in the Arduino Port list?

chipId=0x23342c30
Unsupported processor

That's really weird.
The chip id for a SAMD21G18 ought to be 0x1001xx05, and I wouldn't expect a completely "broken" install to get as far as being able to read the ID at all. Do you have any other weird USB devices connected to your computers?

No, I don't see the board listed next to the COM3 port. I am only allowed to select the COM3 port.

Do you have any other weird USB devices connected to your computers?

When attempting this install on OSX, this was the only USB device plugged into the computer. On Windows I only have my mouse and keyboard connected to the USB ports.

An additional step I took was to test both USB3.0 ports and USB2.0 ports, as I had read that could potentially be an issue. Using different ports did not help.

Lastly, I have since purchased an Arduino Uno Rev3, and have has no issues getting sketches to flash from my Windows machine.

See if you can get the board into bootloader mode by double pressing reset as described here:
https://learn.adafruit.com/welcome-to-c ... oader-3-13
and then see if the METROBOOT folder shows up. Not in Arduino, just in your file explorer window.
