Dear Mr. Babic
Hi,
please use the U-Boot ML for U-Boot related questions. You will find much more help than asking to a single person and your questions can interest many other people.

I try to run a USB Host on a i.MX53 Board. Unfortunately USB does not work. I got the following error message: ?EHCI timed out on TD - token=0x80008c80?.
On a discussion on GMANE I found a post of you, that you run USB on a
mx53_loco.Can you tell me on which source base you are working?
I tested when patches were submitted on a MX53QSB. I have tried now, and USB seems working.

However, with last TOT I get errors:
ERROR: v7_dcache_inval_range - stop address is not aligned - 0xaf56b960
and of course it is not working. Some "git bisect" is needed here...

Do you use the UBoot sources from Freescale?
Absolutely not, only mainline U-Boot.
