JETSON ORIN NANO JETPACK5.1.2 When I use python3 manage.py drive is error OSError: [Errno 16] Device or resource busy #1151

seed0097 · 2023-12-07T11:11:38Z

I have installed the DONKEYCAR project on the ORIN NANO JETPACK 5.1.2 system using the following URL, but I encountered the following error when running the program. The camera in use is C270.

https://github.com/Heavy02011/donkeycar-test-DC50dev3/blob/main/logs/Try03_test-result.md

It's error
(env) jetson@orin-nano:~/mycar$ python3 manage.py drive

There are two cameras present on your orin. typically /dev/video0 is the CSI and /dev/video1 should be USB. You seem to try using /dev/video0 as WEBCAM which results in the error, as its a CSI type.

Please adjust the camera settings in myconfig.py into /dev/video1. Then it should work.

Thank you for your reply.
I have changed the video in config.py to 1, but another error occurs.
When using video 0, the LED on the camera is on until an error occurs and then goes out. This indicates that video 0 should be correct.

Is there still a possibility of I2C being occupied? Currently, I am using BUS 7 with the address 0x40 according to the following website. BUS 1 seems to be using 0x40.
https://jetsonhacks.com/nvidia-jetson-orin-nano-gpio-header-pinout/

#9865, over rides only if needed, ie. TX2..
PCA9685_I2C_ADDR = 0x40 #I2C address, use i2cdetect to validate this number
PCA9685_I2C_BUSNUM = 7 #None will auto detect, which is fine on the pi. But other platforms should specify the bus num.

Heavy02011 · 2023-12-08T05:44:23Z

can you please paste a link to your myconfig.py
have you successfully tested the usb camera with other code like https://github.com/connected-autonomous-mobility/installDonkeycarJetsonNanoJP46-v2/blob/main/tests/test_camera-usb.py

seed0097 · 2023-12-08T06:59:14Z

There is myconfig.py and config.py
https://drive.google.com/drive/folders/1kf6A8L85rkjjGP6ORhDVD0NM491Lr8SE?usp=sharing

Using video 0 open the camera normally.

@seed0097,
It appears that your issue may not be the Webcam and is being caused by the Bus number you have selected for the PCA9685.
Try PCA9685_I2C_BUSNUM = 1

Thank you for your reply.

When I use
donkey calibrate --channel 0 --bus=7
The wheels can rotate normally, but when executing python3 manage.py drive, those errors occur. Changing it to 1 also displays the same errors.

Because BUS 1 seems to be using 0x40???
https://jetsonhacks.com/nvidia-jetson-orin-nano-gpio-header-pinout/

How do I change 0X40 to 0X41 in the DONKEYCAR project?
