Harbhajan Singh (INDIA)
I am working with the Bf527 Ezkit and Trunk distribution. I have external host controller interfaced with the Blackfin.
I am able to succesfully boot the kernel and it detects the root hub and the 2 ports. When i connect a usb device it is enumerated and the details of the device are displayed as follows.
usb 1-2: configuration #1 chosen from 1 choice
scsi0 : SCSI emulation for USB Mass Storage devices
usb 1-2: address 2, EndpointAddress 0x02 use DMA FIFO
usb 1-2: address 2, EndpointAddress 0x81 use DMA FIFO
in the devices list is as follows.
dev/ram6 dev/tty36 dev/usbdev1.1_ep00
dev/ram7 dev/tty37 dev/usbdev1.1_ep81
dev/ram8 dev/tty38 dev/usbdev1.2
dev/ram9 dev/tty39 dev/usbdev1.2_ep00
dev/random dev/tty4 dev/usbdev1.2_ep02
dev/rtc0 dev/tty40 dev/usbdev1.2_ep81
when i tried to mount the file system i am getting the following error.
root:/> mount -t vfat /dev/usbdev1.1 /mnt
mount: mounting /dev/usbdev1.1 on /mnt failed: Block device required
How to solve this mount problem.
Best Regards, Sreedhar.

Do what the error tells you. - use a block device - something like /dev/sda1 (whatever was mounted by the kernel).

I didnt get much information from this error. Is there any option needed to be enabled for this error in menuconfig?
Block device required.

read some basic Linux books on the difference between a character device and a block device. it makes no sense at all to try and access a direct USB end point as a block device like you're doing. only real block devices will work.
