LS1046ARDB MMU and UART Issue

[Faizanbaig]

Hi,

I am executing Uboot on LS1046ARDB Board. With MMU disabled UART is printing successfully  but when MMU is enabled UART is not printing anything.

Am I missing something? Any suggestions would be appreciated.

Thanks,

Faizan

Please refer to the U-Boot README saying:

Memory Management:
------------------

U-Boot runs in system state and uses physical addresses, i.e. the
MMU is not used either for address mapping nor for memory protection.
