[U-Boot-Users] Binary file cat

[U-Boot-Users] Binary file cat

[Adam Bezanson]

Hi,

 

I have ported u-boot to my arm920t based system. I have a unique
situation in that my processor requires a binary header to be placed

In front of u-boot.bin before it is burnt into flash. If the processor
doesn't find this header in flash it will not boot out of flash.

Currently I have the header file as a separate file in the root
directory and when I finish a new compile I have a shell script which

Simply does a 'cat header.bin u-boot.bin > out.bin'. I'd like to get
away from this and add it to the Makefiles so for my board 

I don't have to run this script every time. Before I go editing a
top-level Makefile, I wanted to ask for advice on how I should go

About doing this? Anything I can do in my board-specific directory would
make me feel better.

 

Suggestions?

 

Thanks,

Adam

Your _processor_? I never head something like that. Are you sure it's
not another existing boot loader on your system?

Me too, and it's actually easier that way. trun your binary header in
an object file and edit the linker script for your board to load this
object first.

Best regards,

Thanks, I'll give that a try. I should have clarified "my processor" a
little more. It's a Cirrus Logic EP9312 and yes indeed there is a boot
rom internal to the processor that does these checks for a signature
that I've put in this header. Essentially it's a way for it to determine
if there's a valid image in flash to boot from, otherwise it tries to
boot from other interfaces. 

I certainly didn't want to do a global change to a Makefile for
something like this.

Regards,
Adam

U-Boot on EDB9312 (was: RE: [U-Boot-Users] Binary file cat)

Hi Adam,

I've just read the message about your port of U-Boot for EP9312.
Next month I'll start to work on the EDB9312 evaluation board and I want to 
use U-Boot as bootloader.
As I don't want to reinvent the wheel, I was wondering if your patches were 
made publicly available. It seems they were not included in the CVS repository.



Thanks in advance,

They weren't made public yet but I can certainly do so. I'll look to update
my tree to the latest CVS (it's been awhile) and provide Wolfgang with a
patch to incorporate into CVS.

Regards,
Adam

Hi Adam,

as I've just received the EDB9312, I think I can help you.
If you send me your old sources, I'll start to update the
port for the board to the latest CVS repository.
What do you think?
