[U-Boot] FIT image support ARM architecture ?

[U-Boot] FIT image support ARM architecture ?

[Cyrille Francois]

Hello,

I'm trying to generate a FIT kernel image.

I'm using u-boot 1.3.4 / dtc 1.2.0.

All seems ok when i generates the FIT image

mkimage -l kernel.itb

 Image 0 (kernel at 1)

  Type:         Kernel Image

 Configuration 0 (config at 1)
  Description:  Boot Linux kernel
  Kernel:       kernel at 1

But on u-boot prompt :
=> iminfo

## Checking Image at 00900000 ...
Unknown image format!

I don't masterise all.

However, I have one question :
FIT image support ARM architecture ??
All examples i found talk about PowerPC

I don't think that anybody tested FITs on ARM.  On the other hand, the
concept is generic, so _should_ be no real show stopper on the road.
Otoh I would not be surprised if there are some minor problems waiting
for you to find them....

For a start I'd try to include "CONFIG_FIT" in your configuration ;)

Cheers
