I am not able to use CSI camera and PWM at the same time.
I have successfully configured Jetson Nano to use the RPi HQ camera module using ArduCAM driver
However, I am encountering problems using the PWM output on pin 33.
I am able to configure the PWM output using /opt/nvidia/jetson-io/jetson-io.py script, but whenever I load the camera driver PWM settings are set to default.
Can anybody give some suggestions on where to start to solve this problem?
I have checked the Arducam modified tegra210-p3448-0000-p3449-0000-b00.dtb file and didn’t found the 40-Pin Expansion Header configuration, so it looks like the camera is not using the pin PE6 (header pin 33). However, my configured tegra210-p3448-0000-p3449-0000-b00-user-custom.dtb has section “header-40pin-pinmux”.
you may include those changes and recompile the dtb file for usage.
please also refer to Kernel Customization chapter for building the NVIDIA kernel.
thanks
I have this exact same problem on my Jetson Nano 2GB and I don’t get how the solution should be applied. @Edwin2087 , is your problem solved and how did you do it?
