[U-Boot-Users] [ ramdisk error ]

[김영순]

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.
