What u-boot version are you using, what is the kernel command-line being passed?

U-Boot 2023.01-12.24.10-38609-g8c83f0868f9 (Feb 01 2026 - 11:42:41 +0000)

In u-boot,

>>printenv bootargs

bootargs=arm-smmu.disable_bypass=0
….

console=console=ttyS0,115200 earlycon=uart8250,mmio32,0xf0512000

this is incorrect. console=console=ttyS0,115200 you only want console=ttyS0,115200

you can change this in your u-boot env. It may be worth to resetting the env to u-boot defaults and test.
