I’m using the Iris carrier board and Colibri iMX6DualLite module. After the board is powered on, I get rubbish in the minicom console.

Command used to launch the minicom: minicom -D /dev/ttyUSB0 -b 115200

dmesg output when connecting the Serial2USB module:

If I understood correctly you are using Serial-to-USB adapter between Iris and your development machine. Could you please specify how exactly this adapter is wired to Iris?

Connection looks OK. Have you tested this USB-serial adapter with any other board or computer? Could you try another RS232 cable? Do you have any other Colibri module?

Thanks, I found the problem, I was using DB9 to IDC10 (AT/Everex) version instead of (DTK/INTEL).

Thank you for an update. Glad your problem is solved.
