Hello,

then the same bug may also be in "cmd_reiser.c".

In this case the part of the board design which appears at address 0x00 
of lh7a404 after reset.

Yes, shouldn't be. Initialise ram, move and jump.

I'm quite new to this arm and embedded linux stuff and played a bit with 
a kev7a400 board and a patched u-boot-0.45 and now I will use das u-boot 
with a 2.6-kernel on a small lh7a404-design with mentioned DoC and some 
sdram and several io's

Any hint or doc-pointer on adaption of das u-boot to this lh7a404 soc? 
As it is a SoC, there shouldn't be much board-specific stuff to be done 
for a boot-loader.

MCF5249 support in u-boot

Hello Kit,

Please correct me if I am wrong, but I don't think the MCF5249 has ethernet 
build in. So you would have to connect an external ethernet controller.

Yes, I did. You can find the "TASREG" board which uses the MCF5249 in the 
current CVS (please don't use 1.1.2, use current cvs).

Best regards,
Stefan

"How to trim the U-boot for IBM PPC 405EP board"

Hi All,
I am newbie to U-boot.
I am planning to use u-boot for my customized IBM PPC 405 EP board.
Which includes spartan3s FPGA,89LPC932 controller,GM2120 Genesis chip,4MB
Flash,32 MB SDRAM.
Can you please help me in trimming the uboot ver 1.0.0.
Which is the first file that gets executed at power on the board.
I am going through the source code,but i am in a bit confusion to figure
out the flow of u-boot files.

Thanks in Advance,
Nag

Thanks for pointing out - checked in.

Re: das u-boot and disc on chip

Excuse me if its going OT now. Maybe, you can point me, out of your 
embedded experience, to a better source.

no illusions, maybe it sounds like, yes. I'm just thrown into this 
project with an existing design and looking for solutions. The board 
consists of an lh7a404(arm922t-core),2x64MB SDRAM,64MB Flash DoC, 
Ethernet, USB, 2xUART and extension bus, nothing else. My preferred OS 
is, of course, Linux.

If I understood you right, U-Boot is maybe not the best choice for me, 
because there are only 2KB XIP Flash available at address 0x00000000 on 
startup.

Because of the several boot-modes, the lh7a404 offers, I'm thinking in 
the meantime about to ommit the loader completely and copy the kernel 
image directly from DoC to ram and jump there.

Regards,

Hi Kit,

What do you mean with choose? You seem to have chosen already: the RTL8019. So 
no choice left. 

You probably mean how to integrate the driver for the RTL8019 into your U-Boot 
image. After scanning through the source code I found that a driver for the 
RTL8019 exists (drivers/rtl8019.c). But this driver does not seem to be used 
by any board in the current cvs. So try to integrate the current driver into 
your U-Boot port and fix possible problems.

Best regards,
Stefan

I wouldn't put it like that. IMO your hardware is not the best choice
for you because it is missing a proper boot ROM (256 kB  flash  would
be  just  perfect)  to  allow  you using a decent boot loader without
jumping in loops.

And who will initialize the hardware for Linux?  Who  will  tell  the
Linux  kernel  how  much  memory you have, and pass all the other bot
arguments to it? And how will you get LInux into the DoC in the first
place?

It's software, so all things are possible. But  not  all  things  are
reasonable.

Best regards,

Wolfgang Denk

You can do this in a number of ways.     IBM chose to do all of them.
