Hi,

I am trying to get USB Mass Storage to work on mx6slevk, but I am
getting the following error:

=> ums 0 mmc 1
UMS: disk start sector: 0x0, count: 0x762c00
g_dnl_register: failed!, error: -22
ERROR: g_dnl_register failed
at common/cmd_usb_mass_storage.c:107/do_usb_mass_storage()

On mx6qsabresd it works fine and I am able to mount the SD/eMMC card
on the host PC.

The mx6slevk changes are the same as the ones for sabresd and look like this:

diff --git a/include/configs/mx6slevk.h b/include/configs/mx6slevk.h

Does anyone have any ideas of what may be missing?

Ops, I missed some to copy some pieces. The changes look like:

You might want to check this value:

#define CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP

Thanks for the suggestion. After adding this config the error is still the same:

=> ums 0 mmc 1
UMS: disk start sector: 0x0, count: 0x762c00
g_dnl_register: failed!, error: -19
ERROR: g_dnl_register failed
at common/cmd_usb_mass_storage.c:107/do_usb_mass_storage()

Thanks

Just to let you know that this original problem was caused by an error
in the mx6sl-evk board file, so things look good in the USB stack.

Of course, I never ever doubted that ;-)
