Uart don't work on RPi4 about rust-raspberrypi-os-tutorials HOT 2 CLOSED

I found my own issue. My terminal was configured to send '\r' on enter instead of the required '\n'.

I did confirm that bcm2711-rpi-4-b.dtb is not needed on my board. It also works without config.txt.

Interesting, I did several experiments with the clear outcome that the dtb blob is needed. I was not starting from a raspian image, though, but from the official firmware folder as described in the tut.

Anyways, its the safer call to have the file, since a stale file doesn't hurt, but interesting still that it works for you without it.
