[U-Boot] Using U-boot on the IXP432
Hi,
I have been using a board with and IXP432 for about a year now, starting with Redboot but running in big endian mode. I am now looking at using u-boot for network booting but I would like to run it in little endian mode. Before I get stuck into to porting the code I have a few questions.
1) Has anybody else ported the code to the IXP432? 2) Is there any reason that the IXP cpu configuration sets the bigendian flag and should it be possible just to set it to little endian and will the bulk of the code work without modification?
Thanks
Dave

I've hear about someone I'll try to canctact him but the ixp432 is really simmilar to the ixp425 so it will be not difficult to port IIRC the most important work will be on the network support

no need recently some patch have been send to allow u-boot to load a kernel little endian evenif u-boot is compile as bigendian
so you will not restrict your u-boot to only use a little endian linux or easly an other OS

The ixp npe code is a big endian only binary blob. If you don't want network support you can run the ixp in little endian mode.
