The kernel patch is at http://lists.busybox.net/pipermail/buildroot/2012-April/052585.html, hidden inside a Buildroot patch. I haven't posted it anywhere else because it's a hack to workaround a Qemu problem: the 5208 apparently has support for separate supervisor and userspace stack pointers (through two different registers), but Qemu doesn't emulate that. So I think it's a flaw in Qemu emulation rather than a kernel problem, but it was easier for now to workaround it by just adding one "select COLDFIRE_SW_A7". > Nice to see that it can run under QEMU! Well, as I said, it actually doesn't run very well: if I use /bin/sh as init=, then I can run *one* command, and the kernel crashes :-) So we can say it boot all the way to userspace, but userspace isn't very useful :) Regards, Thomas -- Thomas Petazzoni, Free Electrons Kernel, drivers, real-time and embedded Linux development, consulting, training and support. http://free-electrons.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
