Is the new Raspberry Pi CM5 Rev 1.0 board supported?

[Sparqx73]

I am using the new Raspberry Pi 5 Compute IO Board with a CM5 and I am getting the following error when running a python script to display Raspberry Pi Stats on an Oled which uses the Adafruit Blinka Libraries:

python3 monitor.py
Traceback (most recent call last):
File "/home/pi/OLED_Stats/monitor.py", line 7, in
import board
File "/home/pi/stats_env/lib/python3.11/site-packages/board.py", line 451, in
raise NotImplementedError(
NotImplementedError:
Adafruit-PlatformDetect version 3.75.0 was unable to identify the board and/or
microcontroller running the Linux platform. Please be sure you
have the latest packages by running:
'pip3 install --upgrade adafruit-blinka adafruit-platformdetect'

If you are running the latest package, your board may not yet be supported. Please
open a New Issue on GitHub at https://github.com/adafruit/Adafruit_Blinka/issues and
select New Board Request.

Are you able to advise whether the new Compute Module 5 is supported? Or when it will be supported?

Thanks in advance for your help

@Sparqx73 I'm getting this on the CM5 as well. It looks like we don't have it in the list of supported boards yet.

https://github.com/adafruit/Adafruit_Python_PlatformDetect/blob/main/adafruit_platformdetect/constants/boards.py#L146

There is a guide to allow us to add them ourselves. I'm wondering if anyone has worked on this yet: https://learn.adafruit.com/adding-a-single-board-computer-to-platformdetect-for-blinka

I've worked on this with my brother and together we got it to work by amending the following

I am in the midst of debriefing on what else we might have modified but this will be a good start if you haven't done it already...I will come back and add anything else that we adjusted once I have documented it

Thanks for this @Sparqx73 - that worked for me too. I am using a virtual environment so my locations were different, but these changes resolved the error. 👏

[Sparqx73]

It looks like we were successful in adding the additional entries for the CM5 to make the Adafruit_Blinka libraries work for this new board so I will close this issue.

If this works for you could you please submit one or more pull requests?
