I found an email thread from last year discussing enabling the BBB's
Has there been any update on this? Do I still need to use Ian [Young]'s patch?
I do see in the bboneblk.dts that all 5 uarts are listed, however
dmesg only mentions uart0 and I don't see any additional tty devices
The kernel is ready to go with the uarts, you just need to adjust the
fdt data. Change the status="disabled" to status="okay" for whichever
ones you want to enable, and adjust the pad control settings so that
devices are connected to the right pins.
