I am using LS2088ARDB board, U-boot leaves me in EL2.

So is it that ls2088a does not have EL3? or U-boot leaves in EL2?

I tries executing 'smc' instruction nothing happens.

   - If EL3 was implemented and I would assume it should have trapped

   - If EL3 was not implemented I expect it to my exception routine of EL2.

Look at attached file. This file is available in u-boot source code in NXP LSDK 1709.

See information about EL2 and EL3 in the u-boot.


Have a great day,
