Hi, After searching the mailing list, I found Andreas Hansson comment "Ruby does not work with ARM (due to assumptions about the memory layout). Thus, stay with the classic memory system" http://www.mail-archive.com/gem5-users%40gem5.org/msg11914.html - Sun, 05 Jul 2015
Could some one please confirm if issue is still present or it was solved in recent commits. Thanks in advance for you time.
