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.

  1. precomposed configurations
  2. 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
