Hi Guenter,
Re: ml605
The thing to watch out for with kernel configs for microblaze systems is the
physmem address setting. Unfortunately the kernel does not auto-detect this.
I'm attaching a kernelconfig for the ml605 that works for me and a qemu
commandline.
qemu-system-microblazeel -M petalogix-ml605 -m 256 -serial mon:stdio -dtb
petalogix-ml605.dtb -kernel arch/microblaze/boot/linux.bin -append
rdinit=/bin/sh
Can you also send me the dtb file or even better its source ? I don't think
the one in qemu is correct. It lists the serial port at 0x83e00000, but qemu
instantiates it at 0x83e01000.
Re: pmu
The PMU board does not run Linux, it runs baremetal power-management related
firmware.
Ah, good to know.
Thanks!
