Hi All,

I am trying to use the example: usbmsb together with with my lpcxpresso 1343 board and the embedded artist base board.

According to the readme file:
"When downloaded to the board and executed, the PC will recognize
a USB mass storage device containing a text file."

But with I download it, my PC recognize the USB mass storage but when I click on it I get: Please insert a disk into removable disk....:confused:

Can anyone tell me how I can see that text I am supposed to see???

Thanks,
raph

I found a quick fix:

Just hardcode larger size like this:
MscDevInfo.BlockSize = 512;
MscDevInfo.BlockCount = 2048;
MscDevInfo.MemorySize = 2048*512;

And it will work on Win7.

Enjoy

I'm getting same thing from USBMSD_ROM project.
Should see a USB drive with readme.txt file.
Instead, I see a USB drive, no file, asks me to format drive, then asks to insert a disk. 

Anybody resolve this?

I did several experiments with small FAT12 volumes under Win7. Looks like the rule is simple. The smallest volume must have at least sixteen 512-byte sectors to be recognized by Win7, otherwise Win7 suggests to format the volume and fails while doing so. My solution was to create 6-sector volume padded with 10 phantom sectors. Writes to these are ignored and reads return zeros. The volume will of course behave bad if one attempts to write any file above the 6 sectors implemented.

FYI:

Search my other  posts.  I have made the example work on Win7 by using an external SPI flash memory as the source.

There are some implementation oddities but it does work.

Hi,

Try this to add unto source file:
mscuser.h
/* Mass Storage Memory Layout */
#define MSC_PhysicalMemorySize  (1024 * 3)    /* = 0x0C00 (3kB)*/
#define MSC_MemorySize  (1024 * 8)            /* = 0x2000 (8kB)*/

mscuser.c
uint8_t  Memory[MSC_PhysicalMemorySize];  /* MSC RAM */

main.c
extern uint8_t Memory[MSC_PhysicalMemorySize];           /* MSC Memory in RAM */

    for (n = 0; n < MSC_PhysicalMemorySize; n++) {     /* Copy Initial Disk Image */
        Memory[n] = DiskImage[n];               /*   from Flash to RAM     */
    }

No driver is used for this sample, but the disk image is in FAT12 format. It does work properly under Windows XP and linux but I have reproduced the problem under Windows 7 x64. Perhaps Windows 7 has removed support for FAT12. We will come up with an improved example soon.

Did you get this closer to release yet?

ok, I made some progress:
the same configuration plugged on a XP box is ok.....

Any issues with the driver then...

Hello,

Thanks for your reply.

If you can replicate it, does it mean that you are also unable to access this text file? Or do you have any work-around.

Did anyone ever successfully download the application (usbhid) on a lpcxpresso 1343 board using the embedded artist base board??? This was able to access the text file????

I work on Windows 7, 64bits.

thanks,
raph

I can replicate the behaviour that you see here. As this is an NXP example, I've pinged them regarding this.
