Hi,
Would you be able to guide me, on how I can accomplish
a. trying to download a pre-built ramdisk image, prior to building the linux
kernel? e.g. should I create a new ramdisk-xilinx.bb recipe to separately
download it.
If so, how do I get to stage it so that it downloads it, as soon, as the kernel
sources have been unpacked in the work directory, .. and then copy the
ramdisk.image.gz file over to the arch/powerpc/boot folder?
b. which variables should I use to reference the kernel source work folder to
perform the copy & which task should I use to perform the copy ?
Best regards,
Elvis Dowson
