Jetso Orin Nano

[sarahalipour]

Please add support for jetson orin nano
I've already installed the latest version on jetpack 6.2 using pip3 install --upgrade adafruit-blinka adafruit-platformdetect

Here is the reproducible example:
from adafruit_servokit import ServoKit
which gives below error:
from adafruit_servokit import ServoKit Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.10/dist-packages/adafruit_servokit.py", line 35, in <module> import board File "/home/sahand/.local/lib/python3.10/site-packages/board.py", line 445, in <module> raise NotImplementedError( NotImplementedError: Adafruit-PlatformDetect version 3.77.0 was unable to identify the board and/or microcontroller running the Linux platform.
python version == 3.10.12

I'm experiencing the same issue. I'm running a simple Python test program as follows:

import board
import digitalio
import busio
print("Hello Blinka!")

Upon execution, I receive the following error:

Traceback (most recent call last):
  File "/home/postdoc/Desktop/blinkatest.py", line 1, in <module>
    import board
  File "/home/postdoc/.local/lib/python3.10/site-packages/board.py", line 445, in <module>
    raise NotImplementedError(
NotImplementedError: 
        Adafruit-PlatformDetect version 3.77.0 was unable to identify the board and/or
        microcontroller running the Linux platform. Please ensure you
        have the latest packages installed by running:

        'pip3 install --upgrade adafruit-blinka adafruit-platformdetect'

        If you are already using the latest version, your board may not yet be supported.
        In that case, consider opening a New Issue on GitHub at:
        https://github.com/adafruit/Adafruit_Blinka/issues 
        and select "New Board Request."

Any insights or suggestions would be greatly appreciated! If this is not a platform support issue, what other potential causes should I investigate?

Same problem. I'm guessing this has to do with Super mode on Orin Nano / NX?

Yep, in ($CONDA_PREFIX)/lib/python3.xx/site-packages/adafruit_platformdetect/constants/board.py, find ORIN_NANO, then pick the board that you have (devkit: nvidia,p3768-0000+p3767-0005) and add a new line with nvidia,p3768-0000+p3767-0005-super. Solved

Thanks! This solution worked perfectly for me!

The error has been resolved, but I still can’t move the servo motors. Here’s what I did:

1. Ran the below command in terminal
   python3 -c "import adafruit_platformdetect; print(adafruit_platformdetect.__file__)"

   to display the path used by adafruit_platformdetect.

2. Navigated to the “constants” subdirectory and opened the boards.py file. In my case, the full path is:
   /home/sahand/.local/lib/python3.10/site-packages/adafruit_platformdetect/constants/boards.py

3. Searched for nvidia,p3768-0000+p3767-0005 in the file, then added nvidia,p3768-0000+p3767-0005-super immediately after it.

This change fixed the board’s NotImplementedError. However, when I try to move the servos using:

from adafruit_servokit import ServoKit

myKit = ServoKit(channels=16)
myKit.servo[0].angle = 90

no errors are raised, yet the servos still don’t respond.

For context, I’m using a PCA9685 board with the following connections:

• VCC → 3.3 volts (Jetson Pin 1)
• GND → Ground (Jetson Pin 6)
• SDA → Jetson Pin 3
• SCL → Jetson Pin 5

Jetpack version == 6.2
