Troubleshooting • Re: failure to use UART on pin8/10 (GPIO14/15) on Raspberry Pi 5

Does it work if you (temporarily) use stock Bookworm?
(I have dtparam=uart0_console in my config.txt)

I tried "dtparam=uart0_console" in config.txt and it works for Bookworm. And it also works for Yocto image.
Thank you all!

I understand this parameter sets uart0 as enabled and console as uart0 to replace the original configuration console of uart10.

When I dig further, I don't get what _uart0 is for in the device tree. There are two statements that are relevant in bcm2712-rpi-5-b.dts.
#define uart0 _uart0
...
uart10: &_uart0
...
