Hi ,

I am trying to upgrade my .dfu file into the board. i have converted binary file from GPIO_EXTI available in sample projects.

steps that I have done for flashing the dfu file are

1) flashed dfu sample code into the board

2) pressed user button to switch into DFU mode

3)generated my .dfu file from binary file using 'dfu file manager'

             - entered product ID & version as it was showing in DfuSeDemo.

             -selected binary file to be converted

             -set address as 0x08008000 (which is same as USBD_DFU_APP_DEFAULT_ADD)

    and generated the .dfu file

 

But while upgrading this file to board ,is is not able to leave the DFU mode.

dfu file which is available in STM32F2Cube is working fine.

 

I searched for the same problem on forum but all the tricks i tried aren't working.

Any kind of help on this will be truly appreciated...
