I've done a little more work on this. I've been able to swap the UART pins
around to a certain extent, but it's still being stubborn. I've been able to
move the console output from the main UART from GPIO14 to GPIO32. I've
somehow also managed to get the main UART to output to both GPIO32 and
GPIO1
I've done some more digging, and have made a bit of progress (I think).
After fiddling with the device-tree, I've managed to get the serial port to
show up when running `dm tree`. I appended this block to the end of
bcm2835-rpi-b.dts:
&uart1 {
pinctrl-names = "default";
pinctrl-0
Hi Matthias,
Thank you very much for your help. Unfortunately I'm still a little stuck.

Hi,
I'm working on a project that uses the Raspberry Pi Compute Module 1. Much
like the CM 3, the CM 1 has two UART interfaces - the main UART at ttyAMA0,
and a second "mini-UART" at ttyS0. The project uses the main UART since it
works better at high speeds, so the console has been bumped over to
4 matches
