Since my HDMI port has no output data, I tried to see if the system is booting via serial port.
I first tried serial port on Raspberry Pi, everything is fine, I can read and write to Raspberry Pi via serial port at 1152008N1 setup.
Then I tried it on Jetson Nano. I can receive data fine, except all gibberish.
Therefore, I tried all other configurations, different baud rate, different hardware, software control combinations, none would work.
I am following the steps here: https://www.jetsonhacks.com/2019/04/19/jetson-nano-serial-console/ everything works for him at 1152008N1 yet all I have is gibberish, can anyone help me understand why that is the case?
