Hello,
I´m trying to use Minized in a Ubuntu 16.04.3 LTS system.
After connecting the USB cable, I can program the board through JTAG, but cannot access the UART port.
Looking at dmsg, the ttyUSB0 (uart?) port is getting disconnected soon after the cable is connected.
ttyUSB1 (jtag?) works fine.
I tried using two different boards, same behavior. In a Windows system the JTAG/UART dual USB-to-UART works fine.
Any ideas?
Follows dmsg results.
