Hi Sharjeel, This changeset may be the same as the reason you're seeing the DMA error: https://gem5-review.googlesource.com/c/2380/.
For the functional access error, Ruby does not support functional accesses correctly. Sometimes they work, sometimes they don't. You can search on the gem5-dev mailing list archive for exactly why. The specific error you're seeing my be easy to fix, though. You can dive into the code (e.g., with gdb) to try to fix it.
