[U-Boot-Users] [ ramdisk error ]

Hi,

I have a somewhat embarassing question

regarding u-boot and loading a ramdisk.

I am trying to boot my board based on SEQUOIA using a kernel and ramdisk.

I know the kernel and ramdisk image are good, since I used the same images for SEQUOIA.

Below is a snippet of my boot sequence,

including the error when trying to mount the ramdisk(initrd)

After my board loads ramdisk, I can't see anything through console.

What's wrong???

Thanks,

Sean

The kernel is probably good for the Sequoia board, but if you have some other, custom hardware, you also need a custom port of Linux for it, i. e. another Linux image.
