I have a cuImage kernel in order to support legacy u-boot and a ramdisk image. Kernel boots fine if these two images are
separate and
"bootm $kernel $ramdisk" is used. But I can not make it to
work using
a single multi image that contains the kernel and ramdisk
images. Is
it even technically possible to boot a multi-image with cuboot wrapper?
Try the following steps:
- cp <your ramdisk.gz> arch/powerpc/boot/ramdisk.image.gz
- make cuImage.initrd.<your target>
You can get one Image, cuImage.initrd.<your target>,
including kernel and ramdisk.
A follow up question. With this method, the total image size (uncompressed) is limited to the 4MB (the link address of the boot wrapper)?
No.
Cheers Tiejun
Thanks, -Shawn.
