Somehow you have ended up with either the wrong board module or no board module at all.

DO NOT try to fix this by manually installing a library named board. There is one out there and it has nothing to do with Blinka. You will break things if you install that library!

The easiest way to recover is to simply force a reinstall of Blinka with:
python3 -m pip install --upgrade --force-reinstall adafruit-blinka

Due to the way we share an SPI peripheral, you cannot have two SPI devices with different 'mode/polarity' on the same SPI bus - you'll get weird data

95% of SPI devices are mode 0, check the driver to see mode or polarity settings. For example:

• LSM9DS1 is mode 1, please use in I2C mode instead of SPI
• MAX31865 is phase 1, try using this on a separate SPI device, or read data twice.

This is due to having an older version of spidev. You need at least version 3.4. This should have been taken care of when you installed Blinka, but in some cases it does not seem to happen.

To check what version of spidev Python is using:

$ python3
Python 3.6.8 (default, Oct 7 2019, 12:59:55)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import spidev
>>> spidev.__version__
'3.4'
>>>

If you see a version lower then 3.4 reported, then try a force upgrade of spidev with (back at command line):

sudo python3 -m pip install --upgrade --force-reinstall spidev

Some linux boards, for example, AllWinner-based, do not have support to set pull up or pull down on their GPIO. Use an external resistor instead!

If you are getting a stack trace that ends with something like:

return self._hid.read(64)
File "hid.pyx", line 122, in hid.device.read
OSError: read error

Try setting an environment variable named BLINKA_MCP2221_RESET_DELAY to a value of 0.5 or higher.

Windows:

set BLINKA_MCP2221_RESET_DELAY=0.5

Linux:

export BLINKA_MCP2221_RESET_DELAY=0.5

This is a value in seconds to wait between resetting the MCP2221 and the attempt to reopen it. The reset is seen by the operating system as a hardware disconnect/reconnect. Different operating systems can need different amounts of time to wait after the reconnect before the attempt to reopen. Setting the above environment variable will override the default reset delay time, allowing it to be increased as needed for different setups.

Blinka uses the libusbk driver to talk to the FT232H directly. If you have other FTDI devices installed that are using the FTDI VCP drivers, you may run into issues. See here for a possible workaround:

This is probably only an issue for older versions of Windows. If you run into something like this, see this issue thread:

https://github.com/pyusb/pyusb/issues/120

which describes copying the 32bit and 64bit DLLs into specific folders. (example for Win7)

Check out this issue thread:

https://github.com/pyusb/pyusb/issues/355

which has lots of discussion. It is probably worth reading through it all to determine what applies for your setup.  Most solutions seem to rely on setting the DYLD_LIBRARY_PATH environment variable.

Some CircuitPython modules like may not be supported.

• Most SBCs do not have analog inputs so there is no analogio
• Few SBCs have neopixel support so that is only available on Raspberry Pi (and any others that have low level neopixel protocol writing
• Rotary encoders (rotaryio) is handled by interrupts on microcontrollers, and is not supported on SBCs at this time
• Likewise pulseio PWM support is not supported on many SBCs, and if it is, it will not support a carrier wave (Infrared transmission)
• For display usage, we suggest using python Pillow library or Pygame, we do not have displayio support

We aim to have, at a minimum, digitalio and busio (I2C/SPI). This lets you use the vast number of driver libraries

For analog inputs, the MCP3xxx library will give you AnalogIn objects. For PWM outputs, try the PCA9685. For audio, use pygame or other Python3 libraries to play audio.

Some libraries, like Adafruit_CircuitPython_DHT will try to bit-bang if pulsein isn't available. Slow linux boards (<700MHz) may not be able to read the pins fast enough), you'll just have to try!

It looks like libgpiod may not be installed on your board.

Try running the command: sudo apt-get install libgpiod2
