Hi,

Thanks for the detailed documentation about how to enable RME in tf-a. I try to replace the tftf.bin with the normal boot firmware (edk2) to load the Linux in the normal world, but it fails. The log message from terminal_0 is shown below:

INFO:    RMM init start.                                                                                             

INFO:    RMM init end.                                                                                               

INFO:    BL31: Preparing for EL3 exit to normal world                                                                

INFO:    Entry point address = 0x88000000                                                                            

INFO:    SPSR = 0x3c9

I found a possible solution from the archives:

[https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.org/thread/5NKSFJ52EH4K45RVRN3XOFV5PDJGZKFY/#EROMP2HMAXLTMMRGABEWH6WU3XETWEYL].

I try to modify the dts file under edk2-platform/Platform/ARM/VExpressPkg/DeviceTree/ to change the DDR memory range, which is similar to the modification for RME in [https://github.com/ARM-software/arm-trusted-firmware/blob/master/fdts/fvp-base-gicv3-psci-common.dtsi#L142], but it does not solve the problem.

So, how can I boot Linux in the normal world with RME enabled?

Thanks,
