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.

U-Boot 2011.12-00518-gf56cab3 (Mar 23 2012 - 13:03:38)

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.

Best regards, Stefano Babic
