[U-Boot-Users] configure to run a xipImage

[Joakim Nordell]

Hello!

I would like to run a xipImage. I'm sure I have to tell u-boot that this is the case, but how?
For the moment I have an xipImage that prints "Magic Bad Number" when I try to start it.

Greetings

This is on PowerPC, I assume?

An XIP image has the  following  properties:  it  is  not  compressed
(IH_COMP_NONE),  and  load  address  is  the current start address in
memory (ntohl(hdr->ih_load) == addr); see "common/cmd_bootm.c"  lines
320ff.

Best regards,

Wolfgang Denk

No, sorry. It is an Atmel AT91RM9200 (uCRouter) board running u-boot 1.1.1.
I have built a linux-2.6.15-xipImage to run in the flash memory. My thought is that the start up time will increase a bit. I have insearted the start address for the kernel within the menuconfig -> boot options.
I guess I now have to tell u-boot that the kernel should not be loaded to RAM, and instead run in flash.
Is that correct?
If so, How can I do that?

I'm afraid XIP support has not been added to ARM yet.
