we are working with a i.MX6ULL based board. We are using the debian distribution "Linux imx6ul-var-dart 4.9.88" customized by Variscite which is the owner of the module we are using.
We are now making some further customization to use the module in our equipment, succesfully.
We configured USB#2 as pheriperal with serial gadged enabled and we need to use it in order to redirect the console on.
Changing U-Boot from uart1 to uart3 and the console parameter as ttymxc2 as reported on http://www.variwiki.com/index.php?title=DART-6UL_UART all works fine.
We set console parameter to ttyGS0 in order to redirect almost the kernel console, but the serial terminal on PC Host does not receive anything.
Thanks in advance.
