Got “NotImplementedError: Board not supported” on Jetson Nano

I am trying to follow this tutorial to read analog input.

But instead of using Raspberry Pi, I am trying to use a Jetson Nano to read MCP3008 channel 0 analog input only.

I am following the pin layout in the tutorial on Jetson Nano since it shares same layout with Raspberry Pi.

import busio
import digitalio
import board
import adafruit_mcp3xxx.mcp3008 as MCP
from adafruit_mcp3xxx.analog_in import AnalogIn

# create the spi bus
spi = busio.SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI)

# create the cs (chip select)
cs = digitalio.DigitalInOut(board.D22)

# create the mcp object
mcp = MCP.MCP3008(spi, cs)

# create an analog input channel on pin 0
chan0 = AnalogIn(mcp, MCP.P0)

print('Raw ADC Value: ', chan0.value)
print('ADC Voltage: ' + str(chan0.voltage) + 'V')

The code above throws the error:

    import board
  File "/usr/local/lib/python3.6/dist-packages/board.py", line 98, in <module>
    raise NotImplementedError("Board not supported")
NotImplementedError: Board not supported

I checked the source code, it points to this line.

However, I looked up of the board library source, it does support Jetson Nano because of the line

board_id == ap_board.JETSON_NANO

Any guide can help me further locate the issue will be very helpful. Thanks!

@tokk-nv hi please check this out and see why nvidia nano stopped working?

Greetings,

I am trying to follow this article (http://blog.whatgeek.com.pt/2015/04/raspberry-pi-and-adafruits-neopixel-stick/) but running into "Board not supported". I am using the Jetson Nano. Here is the error below:

Exiting... Cleaning up pins Traceback (most recent call last): File "/home/jetson/PycharmProjects/servoTest/venv/ledTest.py", line 3, in from neopixel import * File "/home/jetson/PycharmProjects/servoTest/venv/lib/python3.6/site-packages/neopixel.py", line 34, in from neopixel_write import neopixel_write File "/home/jetson/PycharmProjects/servoTest/venv/lib/python3.6/site-packages/neopixel_write.py", line 19, in raise NotImplementedError("Board not supported") NotImplementedError: Board not supported

Process finished with exit code 1

Here is a list of my packages:

Any help will greatly be appreciated.

@Hongbo-Miao can you please retry after updating your Blinka and Jetson.GPIO modules? We fixed some issues in Jetson.GPIO that might help you.

@cscholler it looks like you have a different issue. The neopixel code only supports the Raspberry Pi, and no other system that Blinka supports. See https://github.com/adafruit/Adafruit_Blinka/blob/master/src/neopixel_write.py#L14

Hi @swarren I was in a hurry for R&D at that time, so I switched to TX2. I am not able to test again easily with new setup. Feel free to close the issue. Thanks for the help!
