I have written an initialization sequence for Freescale MPC5121e. This CPU contain an OTG and DR module with UTMI+ phy. I tested Linux USB driver for this controller and it works. Infact I analyzed what Linux driver code did and I applied it to my code in u-boot.

Which SOC you are trying to use? I had faced some more issues while porting the USB core layer related to descriptors also.

Hi,
this is the report of my problem. I have initialized the SOC FSL EHCI controller, and I typed usb start from u-boot console. I can see controller and mass storage, but mass storage doesn't seem to be correctly configurated. Can you explain to me what I must expect?
Thank you very much, Francesco.

Hi,
I'm developing an USB EHCI driver for ADS5121e. Now , I completed initialization sequence for my SOC EHCI Controller. My scope is to use with mass storage, but I think that ehci core layer don't work correctly. Do somebody use EHCI CORE layer for Mass storage and it was ok?
Can you report exactly your problem? What happen?
Thank you.
