Hi, i have some problem with uart communication.
I need arduino nano for pwm to control servo and dc motors.
so i tried to use uart through TXD/RXD pins (not USB. I want communicate by pins)
I tested echo program (when i typed on jetson, arduino send it back and turn on/off its built in led)
with minicom (terminal program for linux)
It sometimes display right letter, but usually displays wrong and weird letter and led does not work well too.
When I tried it on Raspberry Pi 3B+, It works well. No single problem.
Anybody knows why this problem happens? and how to fix it?
(+ I use level shifter (3.3v <-> 5v) so I think it is not because of voltage difference)
(+ I also tried with pyserial python code, but same problem occurs)
