Re: [U-Boot-Users] U-Boot and S3c2410

No, a Motorola MPC5200 Lite evaluation board. But I thought that my suggestion is pretty board-independent :)
this is how i created my image:
$ mkimage -n 'Linux PPC MPC5200 2.4' -A ppc -O linux -T kernel -C gzip -a 00000000 -e 00000000 -d arch/ppc/boot/images/vmlinux.gz /tftpboot/MPC5200/vmlinux.img
and then in U-Boot:
=> tftpboot 100000 MPC5200/vmlinux.img
=> cp.b 100000 FF100000 $(filesize)
=> bootm FF100000
(3) So why isn't it booting. Or more correctly why is it resetting after it issues the 'Starting kernel ...' message!! Am I missing some bootarguments?
you don't need to have bootarguments set to see at leaste *some* output I think.. Something more severe is going on I believe

There are huge differences between architectures. While on PowerPC you usually have flash at some high addresses and RAM mapped at 0x0000, you will see flash at 0x0000 and RAM at high addresses on ARM.
You really guessed wrong here.
$ mkimage -n 'Linux PPC MPC5200 2.4' -A ppc -O linux -T kernel -C gzip -a 00000000 -e 00000000 -d arch/ppc/boot/images/vmlinux.gz /tftpboot/MPC5200/vmlinux.img
... which is OK for PowerPC, but seriously broken for all ARM systems I know.

You have to know the memory map of your system, and you have to be aware wat the load address (-a option to mkimage), entry point (-e option) and the address "addr" where your image is stored in RAM when you type "bootm addr" mean.

Good day from sunny finland (o;
- Someone tried to do a Geode port? Probably hard to do so since they're not releasing datasheets/user manuals to anyone...
Was just hoping to replace stupid BIOS from Lippert MovieStar board with u-boot (o;
Or can I try using a normal i386 port and just enable serial port, IDE interface and ethernet which should be common for most platforms?
muchos gracias rick
