[Celinux-dev] Metrowerks Linux USB mass storage device problem

[Sathyan Doraiswamy]

Hi Gangadhar,

USB Mass storage device support is for USB Host (for iMX21 to recognize any
USB memory keys on USB host).

You need to enable USB OTG support and USB Device Mode support.

Ensure that you either have these modules built in or load them at the
prompt:
usbcore.o
usbmx2-otg.o
usbdcore.o
usbd-func.o
storage_fd.o
mx2_bi.o



Thanks and Regards,

Hi,

I am using Metrowerks Linux BSP for I.MX21 processor.

I built the Kernel with USB Mass storage device support. When I connect
the I.MX21 ADS board to the Linux desktop PC there is no device recognized
on
the desktop PC. I do not see the /dev/disk folder. Also I could not see the
device under /proc/devices.

Can anyone help me how I can get the I.MX21 ADS board working as a USB Mass
storage device?


Thanks and Regards,
Gangadhar Kodishala
