[1]    13621 abort (core dumped)  qemu-system-ppc -M ppce500 -nographic -kernel u-boot

As the error message shows: qemu: fatal: Trying to execute code outside RAM or ROM at 0xeff40000.It's Strange.The u-boot I tried is ok on powerpc e500 board.What's more,I have run powerpc linux kernel successfully whih qemu-system-ppc. The version of my qemu is the latest 2.3.50, and I've tried 1.7 have the same problem. Is there anybody faced the same problem?

回答1:

There was a bug in 2.3.50 (bugreport) with this effect. It has been fixed in more recent qemu releases. Why it breaks in v1.7, I don't know. (are you sure?)
