Many DFU errors when using PC application, B Eval

Hi,

I sucseefully flash the firmware required for the B Eval Board to connect to the DFU PC application. I also see that when using the USART IAP toolt that the memory is not right protected, so everything should be ok.

When I try downloading the main internal b eval flash image to internal flash I get

Matching not good. First Difference at address 0x08003000, File byte is 0x78, Read byte is 0x74.

The next thing I try is uploading the DFU image that is already on the SPI flash (demo images) to the pc, to save it in a file. I get the following error warnings:

Target:01

Error Code:Unexpected Error

Operation:UPLOAD

TransferSize:1024

DFU STATE: STATE_DFU_UPLOAD_IDLE

DFU Status OK

Request: Get State Request

CurrentNBlock: 0x0036

CurrentLength: 0x0400

Percent 0%

When I try downloading the SPI flash image supplied by ST for the B Eval, I get (after attempting to sucessfully download for 14 minutes +):

Target: 01

et etc etc (exactly the same as above).

I have tried manny many things including unpacking the demo DFU files and then reforming the DFU with my id numbers etc etc. Nothing works. Also tried obvious things like playing with the 0 1 jump switches etc, no joy.

Anybody know what the hell I am doing wrong?

Thanks!
