OMAP 3530 g_file_storage file error for USB File Storage

Hi Community,

 

I want to use my device as a USB File Storage when I connect it to a Host PC.  I follow the instructions given in www.linux-usb.org/gadget/file_storage.html

I have a problem with OMAP 3530"   .

When I try to command

insmod /lib/modules/2.6.24_mvl5024-omap3530_evm/kernel/drivers/usb/gadget/g_file_storage.ko storage file=/mnt/backing_file stall=0

I get the message

error inserting '/lib/modules/2.6.24_mvl5024-omap3530_evm/kernel/drivers/usb/gadget/g_file_storage.ko': -1 No such device

Also, I tried

modprobe g_file_storage file=/mnt/backing_file stall=0

FATAL: Error inserting g_file_storage (/lib/modules/2.6.24_mvl5024-omap3530_evm/kernel/drivers/usb/gadget/g_file_storage.ko): No such device

    Ok, I fixed the problem. It results from musb initialization error.

    Hi Yunus,

    We are also facing the same issue. 

    While inserting g_file_storage.ko it returns error as 'No such device'. 

    We also get 'musb_init_controller failed' while booting.

    I'm suspecting that it would be the issue with interrupt or DMA. I tried for different options for DMA in menuconfig. It is not working for anything.

    Please find the log below:

    [ 0.361602] musb-hdrc: version 6.0, otg (peripheral+host), debug=0
    [ 0.361938] musb-hdrc musb-hdrc.0: dma type: dma-inventra
    [ 0.361968] musb-hdrc musb-hdrc.0: musb_init_controller failed with status -19
