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.

Andy.

It's my own board, not in the mainline.

As I said, U-Boot works fine. The problem comes when Linux boots.
I've bisected it down to this change:
commit 81bdc155c72ef9e093b388b90c58d8134d870976
Author: Sanjeev Premi <premi@ti.com>
Date: Thu Sep 8 10:47:25 2011 -0400
omap: gpio: Use generic API
That let me figure out the problem - I had to modify my board code
for the new GPIO functions and somehow that's where the problem is.
Still working out the details, but now I know where to look.
Thanks for the help
