Hi Oliver, Sorry for the missing information. I am using version 7.1.63 of the A15 fast model. I'm using the ArmVExpress-RTSM-A15_MPCore.dsc dsc file,and building against the linaro-tracking-2013.05 branch of the uefi-next repository. I have been making some changes, mostly debug related.
I had made the following changes to the DSC file: gArmPlatformTokenSpaceGuid.PcdCoreCount|1 gArmPlatformTokenSpaceGuid.PcdSendSgiToBringUpSecondaryCores|FALSE This was running fine on a single core until I started removing some debug prints.
