Hi Mikeyy, Pretty sure you've already fixed the issue, but I've also encountered it and found out, that U-Boot actually works, but UART doesn't.
The root cause is compatible of `uart10` which is set to "arm,pl011-axi" in DTS for kernel 6.12. "arm,pl011-axi" simply not supported by U-Boot driver. I've changed compatible to "arm,pl011" (as in dtb for kernel 6.6) and UART works again. Best regards, Andrei Lalaev
