There seem to be no errors
I can't login to have access to the terminal
I'm using a Raspberry Pi Zero 2 W
let me know if there's anything else you need to know
I don't have the Raspberry Pi Zero 2 W...
But most of the ARM based microprocessors use U-Boot to boot Linux.
(Have also released a patch for an Rockchip ARM Cortex-A53 SoC in the mailing list in the last years...)
You could read the hardware documentation for Raspberry Pi Zero 2 W and figure out where the debug UART (serial console) is to get
a output from the boot loader. U-Boot also setup's exception handlers with a stack-trace. So you can see if there is an issue with Linux...
You can also investigate the in built-in device tree in U-Boot which is passed to Linux. There you can also see which UART from the SoC is used.
U-Boot also has a command line. :)
