EP8548e - unable to boot linux

acolyte — Fri, 15 Jun 2007 06:20:13 GMT

Hi,

I am using an Embedded Planet board based on the 8548E PowerQuic III processor.

Using the "vmlinux.gz.uboot" and "rootfs.ext2.gz.uboot" from the CDROM "/cdrom/files/", I am unable to boot the kernel on the 8548e.

I'm pretty sure I'm missing something basic, but I'm not too sure what. Can anybody help?

Hi all,
   I have found the same problem using the EP8548rev2.
It seems that, once the Linux image is loaded into the RAM, it doesn't start.
My configuration is quite different, I'm using a rImage.gz that contains both the kernel image and the RAM disk image. This compressed image is stored in FLASH at the address 0xFF000000
I have tried to boot the same kernel via NFS and it works fine, and I have tried to use the same rImage.gz on the EP8548rev1 and it also works. I think there is a problem when the kernel must boot once it is placed in the RAM probably due to a misconfigurations of the rev2 board.
Does anyone have any suggestions?

Thanks, Paolo

Just an update:
I tried to used the BSP for the EP8548v1.1 on the EP8548v1.2 and it didn't work.
The "solution" that I have found is to use the BSP for the EP8548v1.2 mezzanine.

Best regards
Paolo
