Hello everybody,

my company has a project with the STM32F407VG. Since yesterday, we have a problem with flashing the controller. For flashing we use the ST-Link V2. When the ST-Link is in Port SWD, we couldn't flash the Controller, but in Port JTAG it works. We use also Matlab and in this Program we can only flash in SWD. What is wrong??

With kind

Hi brandl.mathias,

Please ensure that you are enabling SWD instead of JTAG in Project Settings.

Which toolchain are you using to compile/run your application?

Best Regards,
