I'm trying to update U-boot on my board from v2011.06 to v2011.12 It's an OMAP 3530, much like the BeagleBoard, with SMSC911x networking. U-Boot is working fine on this board, but when I boot Linux, it can no longer find the SMSC device. If I boot the same kernel with the older U-Boot, the SMSC device works perfectly.
I've looked through the 'bootm' path and I can't see what might have changed that would cause such behaviour. As far as I can tell, everything else is working in Linux with the new U-Boot, just not the SMSC device.
Any clues?
Thanks

Note: I've verified that it's also not working in v2012.04-rc1

So not a BeagleBoard then but something different.
Is the board you are using one of the boards supported in the mainline U-Boot tree or is it an out-of-tree port? If it is in mainline then have you chosen the correct configuration to use?

If you try to use TFTP in U-Boot does that work? If not then I would guess there is a configuration issue with the devices that you have enabled in U-Boot rather than it being an issue with the bootm command.
