I’ve been trying to get some devices connected to the TX1 using serial over USB, but have so-far been unsuccessful. I recompiled the kernel to enable usb serial, as well as the cp210x driver.
Devices appear when querying lsusb and dmesg - including the device product name, manufacturer. I don’t, however, get any new /dev/tty devices. I can manually create a binding between the device and the driver using modprobe, by writing to the /cp210x/new_id file. This results in a ttyUSB0 device appearing when the arduino is connected, but I can’t read or write to it.
cp210x ttyUSB0: failed to set baud rate to 300
cp210x ttyUSB0: failed to set baud rate to 57600
cp210x ttyUSB0: cp210x_open - Unable to enable UART
I’ve tried different devices (uding FTDI and cp210x drivers) and cables, all of which work on my macbook with a simple ‘screen’ session, but so far I have never been able to get serial working over USB with the TX1.
I’m currently using jetpack 3.1, and will try 3.2 if there aren’t other suggestions.
Has anyone else struggled with serial over USB? Any suggestions?
