Other Parts Discussed in Thread: OMAP3530

Hello,

I am using custom board, and having some strange behaviour.

It is based on OMAP3530 2.6.37 TI's SDK.

Usb is configured as OTG,

I tried to connect flash device to the board, and I get the following:

[ 2.905609] musb-hdrc musb-hdrc.0: MUSB HDRC host driver

[ 2.913024] musb-hdrc musb-hdrc.0: new USB bus registered, assigned bus number 2
[ 2.921478] usb usb2: New USB device found, idVendor=1d6b, idProduct=0002
[ 2.928649] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1
[ 2.937469] usb usb2: Product: MUSB HDRC host driver
[ 2.942749] usb usb2: Manufacturer: Linux Elbit version 1.6 2.6.37 musb-hcd
[ 2.950103] usb usb2: SerialNumber: musb-hdrc.0
[ 2.958099] hub 2-0:1.0: USB hub found
[ 2.962219] hub 2-0:1.0: 1 port detected
[ 2.969665] i2c /dev entries driver
[ 2.977020] Linux media interface: v0.10
[ 2.982147] lirc_dev: IR Remote Control driver registered, major 250

The usb is detected but there is no sd attached to it, and there is no /dev/sd*

I also see that when I remove and insert the flash memory, it is not detected any more.

Is there any idea what can cause this ? Is it come HW failure behaviour ?

Thank you!

    Ran,

    The USB card driver support is enabled in your linux? If not, please enable it.
    If yes, first check whether the USB card works by inserting it into any of the normal Desktop Linux and make sure it works and able to mount.

    After enabling the USB card driver support in Linux,
    the following are the general instructions:

    Type the command "fdisk -l" to list the disks that are accessible. Make a note of the device name for the USB card. It will be the first portion of one of the output lines and will look like "/dev/sdc1".

    Type the command "mkdir /mnt/usb" to create a mount point for the USB card. You can replace "/mnt/usb" in any directory that you prefer.

    Type the command "mount -t vfat /dev/sdc1 /mnt/usb" to mount the USB card.
