u-boot and ibm boot

u-boot and ibm boot

[John Chan]

Hello, folks,

my walnut board comes with ibm's boot "rom monitor" (and source code in
CD). I wonder if I can load a linux kernal image (EDLK for example) from
it? I heard that there is another boot code called u-boot. I wonder if
anyone had use it before on Walnut? if yes, do you recommand me to use it?

I would like to add an audio PCI board in the walnut board and would
like to configure/diagnosis the board during the boot time. IBM come
with their ROM monitor source code but the compiler is not free (High
C). I want to have capability to modify the rom monitor/boot loader to
add my own diagnostic code.

Do you think u-boot is good enough?

SB Live works well, use the linuxppc_2_4_devel tree.

Use u-boot, that will give you the flexibility you need.

Yes, the Walnut platform is well supported under U-Boot.

U-Boot is built with a GNU toolchain which is freely available.  I'm not
sure why you'd want to configure an audio device inside of U-Boot, since
you could probably do it just as easily in Linux.  But if you really want
to for whatever reason, you could do it.

u-boot (Redwood6+ibm ppc405)

[Rakesh Jagota]

Hi all,
I am working with Redwood6 board + ibm ppc405. I have downloaded the bootcode
"u-boot" and I think most of the people are using the same bootloader. I
didnt get "Redwood6" board in "board" directory. Can anyone suggest me how
can I get that. And how to load the binary file on the target board.

Thanks in advance,

Rakesh
