yes. The command is "insmod g_file_storage.ko file=backing_file removable=1 stall=0" i took this command from this link http://linux.omap.com/pipermail/davinci-linux-open-source/2007-November/004505.html Ashok > > Regards > swami > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of [EMAIL PROTECTED] > Sent: Monday, November 19, 2007 3:57 PM > To: [email protected] > Subject: using file backed storage support > > Hi, > > By enabling the following option, i am able to file backed storage > support. > Linux Kernel Configuration -->> Device Drivers -->> [*] USB support > ---> > <*> Inventra Highspeed Dual Role Controller (TI, ...) --> [*] > Disable DMA (always use PIO) > > and getting these messages on host side pc > > usb 1-3: new high speed USB device using ehci_hcd and address 65 > usb 1-3: configuration #1 chosen from 1 choice > scsi1 : SCSI emulation for USB Mass Storage devices > usb-storage: device found at 65 > usb-storage: waiting for device to settle before scanning > scsi 1:0:0:0: Direct-Access Linux File-Stor Gadget 0316 PQ: 0 > ANSI: 2 > sd 1:0:0:0: [sda] 131072 512-byte hardware sectors (67 MB) > sd 1:0:0:0: [sda] Write Protect is off > sd 1:0:0:0: [sda] Mode Sense: 0f 00 00 00 > sd 1:0:0:0: [sda] Assuming drive cache: write through > sd 1:0:0:0: [sda] 131072 512-byte hardware sectors (67 MB) > sd 1:0:0:0: [sda] Write Protect is off > sd 1:0:0:0: [sda] Mode Sense: 0f 00 00 00 > sd 1:0:0:0: [sda] Assuming drive cache: write through > sda: sda1 > sd 1:0:0:0: [sda] Attached SCSI removable disk > usb-storage: device scan complete > > > > if i deselect this "Disable DMA" option , then by default DMA mode is > got > selected and getting the following error on host side > > Linux Kernel Configuration -->> Device Drivers -->> [*] USB support > ---> > <*> Inventra Highspeed Dual Role Controller (TI, ...) --> [ ] > Disable DMA (always use PIO) (Now DMA is enabled) > > usb 3-2: new full speed USB device using uhci_hcd and address 34 > usb 3-2: device descriptor read/64, error -71 > usb 3-2: device descriptor read/64, error -71 > usb 3-2: new full speed USB device using uhci_hcd and address 35 > usb 3-2: device descriptor read/64, error -71 > usb 3-2: device descriptor read/64, error -71 > usb 3-2: new full speed USB device using uhci_hcd and address 36 > usb 3-2: device not accepting address 36, error -71 > usb 3-2: new full speed USB device using uhci_hcd and address 37 > usb 3-2: device not accepting address 37, error -71 > > On Board side > ------------- > <6>g_file_storage gadget: File-backed Storage Gadget, version: 28 > November 2005 > g_file_storage gadget: File-backed Storage Gadget, version: 28 November > 2005 > <6>g_file_storage gadget: Number of LUNs=1 > g_file_storage gadget: Number of LUNs=1 > <6>g_file_storage gadget-lun0: ro=0, file: /root/backing_file > g_file_storage gadget-lun0: ro=0, file: /root/backing_file > <7>musb_stage2_irq 807: SUSPEND (b_idle) devctl 99 power e0 > <7>musb_stage2_irq 807: SUSPEND (b_idle) devctl 99 power e8 > <7>musb_stage0_irq 659: BUS RESET as b_idle > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage2_irq 807: SUSPEND (b_peripheral) devctl 99 power e0 > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_i9: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage0_irq 659: BUS RESET as b_peripheral > <7>musb_stage2_i807: SUSPEND (b_peripheral) devctl 99 power e0 > > any pointers on this would be helpful > > > Ashok > > > > > _______________________________________________ > Davinci-linux-open-source mailing list > [email protected] > http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source > _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
