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? #!stm32f4-disco

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.
