I have been using the jetson TX2 with Astro carrier (rev. F) successfully but now, I need to connect it to another microprocessor using a serial RS232 with a 57600 baud-rate.
I have tested sending information from one laptop to the carrier (
echo -ne '
echo -ne ‘\033[2J’ > /dev/ttyS0
33[2J' > /dev/ttyS0
) and I am able to receive it successfully.
When I connect it to the microprocessor, at first I am able to verify that the carrier is receiving data (gibberish). After a couple of seconds, the system enters in a weird state (with command line errors running through the screen).
I guess that this behavior is caused by the serial console on port 0.
I have connected a USB-serial converter and everything works correctly.
I have also tried
In this case, the board shuts-down after that couple of seconds and I am not really sure if the changes were successful (when I run
setserial -g /dev/ttyS0
, I get the following output:
/dev/ttyS0, UART undefined , Port: 0x0000, IRQ: 36
I am also aware of
and performed the changes in step 1. When trying to access the files in point 2, I get an encoding problem. I can find serial@3100000 but the following symbols are just gibberish.
I also tried sending data through the other RS232 port present in the Astro carrier but I wasn’t successful.
Any pointers will be highly appreciated.
