Thanks for the tip. Now I am using uImage file to boot MV Kernel from U-boot on Embedded Planet EP8260 board. But it seems to be stuck after uncompressing:

=>tftp 0x400000 uImage.ep8260 ARP broadcast 1 TFTP from server 10.0.0.1; our IP address is 10.0.0.2 Filename 'uImage.ep8260'. Load address: 0x400000 Loading: ################################################################# ############################################################### done Bytes transferred = 655335 (9ffe7 hex)

=> imi ## Checking Image at 00400000 ... Image Name: MV Linux Kernel Image for EP8260 Created: 2003-07-10 13:09:51 UTC Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 655271 Bytes = 639.9 kB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK

=> bootm 0x400000 ## Booting image at 00400000 ...

OK Uncompressing Kernel Image ... OK

Nothing happens after this…….

I tried to enable the Pipeline in the boot which results in some extra characters after "Uncompressing Kernel Image ... OK".

I used following to make uImage.ep8260 file

../u-boot-0.3.0/tools/mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 - n "MV Linux Kernel Image for EP8260" - d /prj3/kernel/arch/ppc/boot/images/vmlinux.gz /tftpboot/uImage.ep8260

Thanks

I am using u-boot to boot an EP8260 board. However once I load/tftp Kernel ELF file to 0x400000 and try to run the kernel from 0x410000, it crashes... I used the same ELF file with Embedded planet's boot loader and it works fine. Any pointers....

Read the README. U-Boot does not use ELF files to boot Linux.
