Reference this guide http://gem5.org/ARM_Linux_Kernel , I made linux kernel for ARM and run it using gem5.debug. Running failed with error log as following.
The key point is that packet->isError() return true. What's meaning of this method? How do I configure gem5 or linux kernel so that I can start simulation? Thanks.
