USB storage in u-boot with i.mx287?

Hi everyone!

I'm trying to use a USB mass storage dongle in u-boot. I would like to load the kernel, the fdt blob and other files from it, but u-boot doesn't detect it. The OS does.

The output I get from u-boot is

CCARDIMX28 # usb start
(Re)start USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 0 Storage Device(s) found
       scanning usb for ethernet devices... 0 Ethernet Device(s) found

I tried different dongles, I set the USB enable pin, I patched u-boot like this -> http://git.denx.de/?p=u-boot.git;a=blobdiff;f=common/usb_hub.c;h=652a104361f63ee715a99e924ccd1145a2c...
but anything changed.
I read that someone can get the usb device detected from u-boot -> https://community.nxp.com/thread/474963 so I don't get why I can't.

Thank you for your help.

Hi Igor.

Do you think my problem could be just in the u-boot image or should I check other images?

Anyway I'll post on DIGI Forum.

Thank you.
