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 !
Help you with what, exactly?
You haven't actually stated any problem yet ...
the problem is i can't tick the trace option !
What version of ST-LINK do you have? If it requires one version and you have another, consider getting the version you need.
What board/chip are you trying to connect to? What type of connector? What type of trace are you attempting?
The ST-LINK isn't a Trace pod, these typically run $1000-1500 (ie U-Link Pro or J-Trace)
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 ?
