Hmm, I thought there was an option for this but I can't find it in the config, so I must have been misremembering somehow. > When I say "it doesn't work", it means that nothing happen when > starting qemu: no trace, it looks like it's running an infinite loop. Not even "Uncompressing the kernel" ? If you want to track down what's going on then you'll need to connect an ARM gdb up to qemu and single step through the boot process, I'm afraid. > BTW I'm wondering which kernel source I should use to build kernels > for such plateforms (realview, vexpress, versatile) ?

I think the mainline kernel sources should in theory work (in particular if they work with 512MB then that's a good sign...) but I'm not a kernel expert; mostly I use other peoples' prebuilt ones. -- PMM
