I set up a Nvidia Jetson Nano Development Kit with the latest version of Jet Pack, and modified the GPIO pins to use. However, Most of the pins (except for the five pins of SPI1) all do not behave as expected. Issue being their voltage reamains at around 1.6V regardless of high/ low command being sent to the port. They do go up to 3.3V/ 0V sometimes but it’s not stable (will drop back to 1.6V after some time). Most importantly, this behaviour also affects the PWM pins, hence I could not get the PWM signal out from the respective pins at all.
I would like to check whether is this a hardware issue of the board itself. Is this board defective? Asking this because the Jetson Nano Developer Kit User Guide stated that all the signal pins are using 3.3V for signal interfacing.
Please advice. Thank you.
