Reading a file from USB STORAGE device from U-boot in OMAPL-138 platform，but I don not find usb device

Tracking code to find that function which (usb_get_descriptor) return -1;

As for as I know only musb port is supported in uboot for OMAPL1-38 and not OHCI. Can you check if OHCI platform glue layer is available for OMAPL1-38?

Ajay

Thanks Ajay

You say, How do I set to make 138 support usb2.0 in the musb.

Changes in u-boot/include/configs/da850evm.h

Remove "#define CONFIG_USB_OHCI         //使能USB_OHCI协议的支持"

Refer http://processors.wiki.ti.com/index.php/Configuring/Building_U-Boot_for_OMAP-L137#USB_Storage_Support

I remove "#define CONFIG_USB_OHCI "

 Inserted in the u disk at usb1.1 or usb2.0 by AminiB Cable ,

when I "usb start", result,

No USB Device found
0 Storage Device(s) found

Are there any macro does not release?

Thanks!

I tested usb1.1,found that No-u-disk connected through "usb start" to find equipment,but don not find mass storage

But, remove "CONFIG_USB_OHCI"  ,"usb start" donnot find the device and mass storage

I didn't understand statement "I tested usb1.1" ? OMAPL1-38 has two usb ports. one is OHCI port which is available on EVM as standard-A receptacle (same as PCs have). OHCI supports only usb1.1 devices. Second is musb port which is mini-AM receptacle. musb port supports both usb2.0 and usb1.1.

For uboot usb testing you need to connected the usb device to musb port using mini-A plug (connects to EVM musb port) to Std-A receptacle (connects to USB DISK) cable.

Ajay

I will test ,then ask you

Thanks

When I test musb port, I need to release "CONFIG_USB_EHCI"?

For uboot usb testing I need confirm that connected the usb device to musb port using mini-A plug.

But I donnot find decive.

Follow:

/include/configs/da850evm.h

Hi Ajay:

I try to at da850evm.h defined:

#define CONFIG_USB_OHCI_NEW     1
#define CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS 2
#define CONFIG_SYS_USB_OHCI_REGS_BASE 0x00a00000
#define CONFIG_SYS_USB_OHCI_SLOT_NAME "at91sam9263"

then "usb start", result:

1 USB Device(s) found
scanning bus for storage devices... 0 Storage Device(s) found

then "usb info",result:

1: Hub,  USB Revision 1.10
 -  OHCI Root Hub
 - Class: Hub
 - PacketSize: 8  Configurations: 1
 - Vendor: 0x0000  Product 0x0000 Version 0.0
   Configuration: 1
   - Interfaces: 1 Self Powered 0mA
     Interface: 0
     - Alternate Setting 0, Endpoints: 1
     - Class Hub
     - Endpoint 1 In Interrupt MaxPacket 2 Interval 255ms

But, i think that this port  is not what I need. 

then I try to defined "#define CONFIG_USB_EHCI" ,but did not succeed

Thanks.

Hi All

I confirm:

1. Vbus have power on

2. Cable is miniA

3. macro about musb defined

But "usb start"result

(Re)start USB...
USB:   scanning bus for devices... New Device 0
usb_control_msg: request: 0x6, requesttype: 0x80, value 0x100 index 0x0 length 0x40
usb_new_device: usb_get_descriptor() failed
No USB Device found
       scanning bus for storage devices...0 Storage Device(s) found

I donnot kown that I ignored what

Thanks!

Sustained attention in......

With analysis of the same problem.

Thanks!

You may want ti look at pinmux settings of usb pins specially DRVVBUS pin.

Regards,

Ajay

I found that in the "da850evm.c" does not have usb setting information.

#endif

so in the function "board_init" does not have "davinci_configure_pin_mux" about usb_pins.

Is this fase?

Thanks!

I try to change a uboot version, but the result was the same

Hi   LQ,

Did u find the solution to this problem?? Pls let me know....Thnaks
