Hi I have a stm32f429 board which i bought recently.

When I try to flash the board the code gets downloaded, but after that when I try to flash again I get this error

 

''Internal command error''

 

''Error: Flash download failed - Targer DLL has been cancelled ''

 

Once this happens I have to erase the board by connecting BOOT0 to VDD, but again once after flashing this program the error happens again

Why is this?

Hard to say, perhaps your code is doing something to break the debug interface/pins?

Suggest to try the ''Connect under Reset'' type options in the debugger configuration.
