Hello!
I'm trying on getting all 6 UARTs of the PicoCOM1.2 working. We do require all of them for our use case.
I'm currently seeing only 5 of them (See $ ll /dev | grep ttymxc output below). Not sure if this is missing in the kernel, or I'm missing some configuration in uboot.
It's noteworthy to state that I've used the default F&S Kernel + Dtb and only have some minor changes in uboot - mainly additional libraries. Tough it also only lists 5 devices with the
vanilla uboot config.
Could someone tell me how to get the sixth UART to appear?
Linux Version
# uname -a
Ttymxc's
# ll /dev | grep ttymxc
Code
- lrwxrwxrwx 1 root root 12 Jan 1 00:00 login_tty -> /dev/ttymxc0
- crw-rw---- 1 root dialout 207, 16 Jan 1 00:02 ttymxc0
