Hi Prince, Looking at your patch I see the following two changes: 1. Reduce FSP Temp Ram size from 152KB to 64KB: - gIntelFsp2PkgTokenSpaceGuid.PcdFspTemporaryRamSize|0x26000 + gIntelFsp2PkgTokenSpaceGuid.PcdFspTemporaryRamSize|0x10000 This makes sense because now that the FSP is using the single stack it does not need as much temp ram. 2. Increase the size of the platform's PEI phase stack from 128KB to 256KB: - gSiPkgTokenSpaceGuid.PcdPeiTemporaryRamStackSize|0x20000 + gSiPkgTokenSpaceGuid.PcdPeiTemporaryRamStackSize|0x40000 This also makes sense because the FSP is now running on the same stack as the rest of the platform code, so more space will be needed to run MRC. What I am questioning is if we really need 256KB? Looking at the numbers from before, it seems like MRC was running OK with only 152KB of stack space, does platform code really use that much stack space _at_the_same_time_ that MRC is running? Or maybe, the newer version of MRC uses more stack space now? The basic summary is... have you tried booting with gSiPkgTokenSpaceGuid.PcdPeiTemporaryRamStackSize|0x26000?
