I'm a beginner to stm32 world, and currently using STM32F407VG and the KEIL version is MDK 5.30. I started with the basic example blinky code. And when I'm trying to flash the code a dialogue box is popping with a message "Command not su…

Hello,

I am trying to find out GPIO mapping on a board with an STM32F407 (which firmware function is related to which GPIO). I know I could do it using a LA, but pins are note very accesible.

I have no access to source code so... I only have a firmware…

I wonder if the Keil's DFPs just copy the HAL releases, or are they reworked in some way?

Especially, I wonder if it is possible that the bugs which are discussed in the ST forums are fixed in DFPs.
