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

[pwaleka]

Hello everyone

I am facing the same (or similar) issue like those reported here https://github.com/adafruit/Adafruit_Blinka/issues/179 and here https://github.com/adafruit/Adafruit_Blinka/issues/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.

Output of the cpuinfo is following

I tried adding b03114 to the list of revisions in Boards.py like described in https://github.com/adafruit/Adafruit_Blinka/issues/179 however I am running another issue

Traceback (most recent call last): File "/home/pi/code_scanner/gate-enabler-pixels.py", line 66, in switchOffPixels() File "/home/pi/code_scanner/gate-enabler-pixels.py", line 37, in switchOffPixels pixels.show() File "/usr/local/lib/python3.7/dist-packages/adafruit_pypixelbuf.py", line 211, in show return self._transmit(self._post_brightness_buffer) File "/usr/local/lib/python3.7/dist-packages/neopixel.py", line 167, in _transmit neopixel_write(self.pin, buffer) File "/usr/local/lib/python3.7/dist-packages/neopixel_write.py", line 24, in neopixel_write return _neopixel.neopixel_write(gpio, buf) File "/usr/local/lib/python3.7/dist-packages/adafruit_blinka/microcontroller/bcm283x/neopixel.py", line 74, in neopixel_write "ws2811_init failed with code {0} ({1})".format(resp, message) RuntimeError: ws2811_init failed with code -3 (Hardware revision is not supported) swig/python detected a memory leak of type 'ws2811_t *', no destructor found.

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? https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/installing-circuitpython-on-raspberry-pi#blinka-test-3030038-17

All changes were undo'ed. However blinkatest.py is showing the following: pi@raspberrypi:~/code_scanner $ python3 blinkatest.py Hello blinka! Digital IO ok! I2C ok!

@pwaleka Is this issue resolved?

Closing due to lack of response.
