NotImplementedError("Board not supported {}".format(board_id))

[pwaleka]

Hello everyone

I am facing the same (or similar) issue like those reported here #179 and here #66

Basically when running simple script I get the following Error

File "/home/pi/code_scanner/gate-enabler-pixels.py", line 3, in
import board
File "/usr/local/lib/python3.7/dist-packages/board.py", line 175, in
raise NotImplementedError("Board not supported {}".format(board_id))
NotImplementedError: Board not supported None

Output of the detect.py script:
python3 detect.py
Chip id: BCM2XXX
Board id: RASPBERRY_PI_4B

Is this a DragonBoard 410c? False
Is this a Pi 3B+? False
Is this a Pi 4B? True
Is this a 40-pin Raspberry Pi? True
Is this a Raspberry Pi Compute Module? False
Is this a BeagleBone Black? False
Is this a BeagleBone Green? False
Is this a Giant Board? False
Is this a Coral Dev Board? False
Is this a Coral Dev Board Mini? False
Is this a SiFive Unleashed? False
Is this a PYNQ Board? False
Is this a Rock Pi board? False
Is this a Clockwork Pi board? False
Is this an embedded Linux system? True
Is this a generic Linux PC? False
Is this a UDOO Bolt? False
Is this an ASUS Tinker Board? False
Is this an STM32MP1 Board? False
Is this an OS environment variable special case? False
Raspberry Pi detected.

I tried adding b03114 to the list of revisions in Boards.py like described in #179 however I am running another issue

Thanks in advance for any hint here

That rev code is in the latest version of platform detect:
https://github.com/adafruit/Adafruit_Python_PlatformDetect/blob/168ff6b66548e8873d5e05ecbe4f24d2e8b22124/adafruit_platformdetect/constants/boards.py#L395
so you shouldn't have need to add it. Are you using the latest version of the library?

https://www.activestate.com/resources/quick-reads/how-to-update-all-python-packages/
is handy for updating all libraries!

[pwaleka]

The latest version(s) of the libraries I have got installed are following:
pi@raspberrypi:~/code_scanner/tools $ pip3 list
Package Version

---

Adafruit-Blinka 5.9.2
adafruit-circuitpython-neopixel 6.0.0
adafruit-circuitpython-pypixelbuf 2.2.0
Adafruit-PlatformDetect 2.23.0
Adafruit-PureIO 1.1.8

Did you undo any of the manual edits you mentioned doing? Like changing board.py.

What happens if you run the Blinka test?

All changes were undo'ed. However blinkatest.py is showing the following:

@pwaleka Is this issue resolved?

[caternuson]

Closing due to lack of response.
