Yes, revD.

You did not really understand what I mean. I am not talking about using
the USBs host/device from u-boot. The i.MX28 is capable to boot via USB.
In this case the SOC's ROM implementes a HID device and you can use
some tools on your PC (see previous posting) to download the code (boot
jumper setting 0-0-0-0. I tried it with Freescale's sb_loader (Wind**s).
This works fine when downloading a u-boot (imx28_ivt_uboot.sb) based on
Freescale's 2009.08 source + imx-bootlets-src-10.12.01. But it does not
work when using sb_loader with u-boot.sb build from the u-boot-imx repo.

I can can imagine that the SPL code somehow breaks the internal download
code.
