U-BOOT !!!!!!!!!!!!

Hi Scott,

Sorry, I did exactly like you said but this is what I got:

1. Use the zImage (the elf from the boot/compressed tree) and create a binary. The binary should

be passed to mkimage with compression &#39;none&#39; and the load and entry point addresses 0080_0000 above your ram base. In your case this should be 0180_0000. mkimage would look like:

$ mkimage -C none -e 0x01800000 -a 0x01800000 -d zImage.bin <<other parameters>>[/b]

$ ./mkimage -d zImage.bin -A nios2 -O linux -T kernel -n "Welcome to uClinux with MFM" -a 0x01800000 -e 0x01800000 -C none zImage.img

2. Use the vmlinux (not from the boot/compressed tree) and create a binary. Compress the binary

(e.g. vmlinux.bin.gz). Pass the compressed binary to mkimage with compression &#39;gzip&#39;. Set the

load and entry point addresses to some valid address in ram (the kernel can relocate itself).

But since u-boot will be decompressing, you might as well set the load/entry addresses to

the actual VMA: 0x0100_0000:

$ mkimage -C gzip -e 0x01000000 -a 0x01000000 -d vmlinux.bin.gz <<other parameters>>[/b]
