Problems regarding Jetson nano

Recently we started using Jetson Nano board in developing Autonomous wheel Chair. It will be of great help, if we get technical support from NVIDIA or permission to visit your office in sorting the issues listed below. 1. To produce PWM signals using Jetson Nano I/O pins. The suggestion mentioned in the NVIDIA discussion forum also was tried.But we were not able to generate PWM signals. 2. We have also faced issues while interfacing Pi camera V2 with Jetson Nano. It always shows the message “No camera available“. 3. The last issue is that the HDMI cable which we were using initially, suddenly stopped working and we faced the same issue for 2 HDMI cable.

Please create individual 3 topic for them should be able get support well.
