uboot uclinux boot

hi Scott,

thanks for the info, my load address for kernel image is 0130_0000, mistakenly I wrote 0100_0000.

I have noted down bootm limitation also.

I will update the forum as soon as I get any success.

thanks once again

since you're using a compressed kernel ...

... you need to load the image somewhere else. otherwise, u-boot will decompress

the kernel over the compressed image (the compressed image gets corrupted).

try downloading the image to a higher address, say 0150_0000 or something.

then when it is decompressed to 0100_0000 you won't have any overlap.

specifying a ramdisk using the bootm command won't work. the kernel doesn't

accept parameters from the bootloader. you'll have to use another technique.

yes, there are many people who used u-boot to with several versions of linux

(and ecos) on a variety of altera (and custom) boards. don't get frustrated,

you're very close to success :-)
