Please stop creating duplicate threads!

Anyway, if you want assistance, then you might want to post more details. For example:

- which board are you using?
- exactly which examples you started working from?
- which flash disks work / don't work. For example is it size related? And how are the disks formated?

Regards,
LPCXpresso Support

excuse me if I create a duplicate thread, honestly I can not find any related page or thread to it in net....

-I've designed my own board.
-I found an example in the net, I attached it to this mail.
-it dose not have any specific rule, for example it work proper with hp(4GP) or Philips(8GB),but it dose not work with silicon power(4GB)!!!

excuse me for my bad English..
thanks for your attention..

Hello

I am also having problems with my LPC2468 working with some flash drives, even of the same manufacturer, same size.

The code we are currently using is a version of usbhost_lpc2468.c

What we would like is the latest version of

USBHostLite for LPC23xx/LPC24xx V1.00 (Jan 4, 2010)

from the site:

http://www.lpcware.com/content/project/nxp-peripherals/usb-nxp-microcontrollers

because the link is broken. It goes no where.

Or do you have a driver for the USB for LPC2468 processor?

Our failure is inside the

if (!(TDHead->Control & 0xF0000000)) {
        return (OK);
    } else {
        return (ERR_TD_FAIL);
    }

where we read a 0x5.... instead of a 0xF.....

Please advise

Code 5 = device not responding.

Might need to give it more time depending on the operation.

I have have some flash disks take 800 ms (nearly one second) to respond to (I think) DeviceInquery for example.
Went a bit faster after that.

Anyway read the OHCI spec. Completion codes are on page 33.
EDIT: Document page 33. PDF Viewer page 47.

EDIT2: See my (unanswered) post here

EDIT2a: This topic should be in "USB" and not "Peripherals"

Cheers, Mike.
