S32G3 u-boot loading OS in EL1 with mmu not working properly

Dear Community members,

 

I am facing a issue with S32G3 RDB3 u-boot, that when it is loading a microkernel image which is build for El1 (non hypervisor). After launch the mmu does not work properly. In the initilal startup code in microkernel if we want to disable mmu the execution just stops for several seconds causing boot delay.

The same logic when tested on i.MX8 hardware works properly.

This is the first instruction executed in microkernel after switch from u-boot in _start assembly function.

I am using the RDB3 hardware and default RDB3 yocto build. Is there any settings in ATF causing MMU related such behaviour

Regards,
Misbah
