Hi Mike, > You are closer than you think with the ARCH=powerpc. You need to load one more > binary file into ram and specify one more address for bootm. You need to load > the device tree blob (DENX addresses this at > http://www.denx.de/wiki/view/DULG/ > LinuxFDTBlob). Thanks again DENX?
As you may have noticed, this is a wiki, so many people participated in writing up the documentation... > Following your ARCH=powerpc build you should see a NEW file in your build > output: rootfs/boot/lite5200b.dtb Just as a reminder, as U-Boot needs to fill in at least the "chosen" node in the fdt passed to the kernel, we have to reserve some space in the .dtb file. This can easily be done during the "normal" kernel compilation by export DTS_FLAGS="-R4 -S0x3000" before the compilation. > 1) edit arch/powerpc/boot/dts/lite5200b.dts > > a. change line 45 to: reg = <00000000 8000000> // change to > 128M > from 256M. Someone needs to look into this, because usually the amount of RAM should be passed correctly to the Linux kernel after dynamically finding the correct amount.
