Hi Joao, I can't really tell where the problem is but when you configure your system you have to make sure that the cores have a stage 2 MMU for both the data (dstage2_mmu) and the instruction side (istage2_mmu).

I took as inspiration the work of powerjg, (thank you a lot for sharing your code, by the way). However I am using the ARM model, instead of the x86, which means that I should use the ArmTLB instead of the X86TLB. I instantiate it and pass it as parameter to my accelerator. When I use the X86 model (and consequently the X86TLB) everything goes fine, but when I try to instantiate the ArmTLB, I simply get: fatal: fatal condition !stage2Mmu occurred: Table walker must have a valid stage-2 MMU. Does someone came across with this problem and can give me a hint about how to solve it? Thank you very much in advance.
