Hello experts,
I am trying to enable MMU on LS1046ARDB Board and have generated MMU translation table . I am able to write entries into translation table . I am running my code from flash memory and translation table base address is in DRAM . As soon as MMU bit is enabled in sctlr register I am getting Translation at level 1 error. Please can anyone help me where/what can be the mistake?
Any help would be appreciated.
Below is the assembly code .
Thanks.

I overlooked caching issues within a single core. The problem was that, after turning the MMU on, the CPU and table walk unit didn't have the same view of memory. ARMv8 Cortex-A Programming Guide states that cache has to be cleaned/invalidated to point of unification (same view for a single core) after modifying tables.
