Hi there,
We have "sama5d3 xplained" board. All peripherals are working perfectly except TFT LCD and USB CDC ACM Device.
I am following this official guide
I tried below both methods.
- precomposed configurations
- configured through ConfigFS
First method does not have any effect on my PC dmesg.
modprobe g_serial
Below my pc ubuntu syslog given for method 2 tail -f /var/log/syslog
