Hi , i have a problem with the trace function in keil he requiers a version off ST-Link /V2 ... and later can you help me !
i'm using ST-Link 4 , my board is STM32F407VG i did the firmware update but it doesn't work !
"my board is STM32F407VG" --> This is a target device and not the board.
Exactly which board are you using ?
