Hi I have been trying to get the mini UART (UART1) to work in Barebox on the RPI Compute Module 3+. I already have the changes made in config.txt and this works fine when I boot into the main Linux code. However, in Barebox, the output always comes out on the main UART (UART0) and that is wired to the Bluetooth module on my platform. I have tried modifying the device trees and cannot seem to get any output. I also ensured that I added the RPI CM3 output target as a config in rpi_defconfig.
I've tried turning off the PL011 config option and also changing the device tree to reference UART1 and set the chosen stdout-path to point to this UART, but when I do this I just get a lack of any serial output. I am also wanting to use the alternate pins (32 & 33) for UART1, so I am thinking that something else needs to be changed. Has anyone managed to get this to work?
