Hi Chen,
You should use the dev repository, and the EMM platform. The reason you're seeing that issue is you're trying to use a kernel compiled for a PBX system on a EMM one. You can download a EMM kernel on the downloads page.

I am not quite familiar with those supported ARM platforms, and just wondering if 256MB is a hard limit for realview_xx and VExpress_xx machines. If so, does GEM5 support any other ARM platforms that allow more memory, say 1 or 2G? >> > >> > Best, >> > Chen > _______________________________________________ >> > gem5-users mailing list >> > gem5-users@gem5.org >> > http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users [1] >> >> _______________________________________________ >> gem5-users mailing list >> gem5-users@gem5.org >> http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users [1] > > _______________________________________________ > gem5-users mailing list > gem5-users@gem5.org > http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users [1] Links: ------ [1] http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users [2] http://gem5.org
