Hi Anish, On 25/04/14 00:05, Kapania, Ashish wrote: I apologize for causing any confusion. The xen.lds file I modified is generated and hence not tracked by git. I had forgotten about the change and running "git status" was not telling me that I modified the file. Another point I wanted to make was that I always do a "make distclean" before rebuilding xen but the xen.lds file does not get regenerated. I had to manually delete it to force regeneration. Maybe thatâs a bug ? I tried the Ctrl-A * 3 + press 'd' sequence and found that dom0 is in ABT mode. I tried debugging a little with JTAG (My JTAG setup does not work well in HYP Mode so I cannot debug xen with it) and found that the ABT happens in Linux/arch/arm/boot/compressed/head.S's __setup_mmu code. The exact instruction that causes the abort is a store instruction that is attempting to write a page table entry to 0x80004000. MMU stage 1 translation is disabled at this point so it looks like the Stage 2 translation is not mapping 0x80004000 address. Is there some step that I am missing that is suppose to tell xen to map the memory used by linux to store page tables ? Can you post the console output of Xen and DOM0 (if you have some)? I'd like to seems how Xen populates the RAM for DOM0.
