JTAG connection with STM32F7

I'm using a STM32F7 MCU with a JTAG connection (4-pins used). The schematic is attached. It uses the 10 pin connector standard, and it's connected to a ST-LINK using the olimex conversor.


The SWD works correctly, but the JTAG can't be connected (I'm using the ST-LINK Utility). Also, I have already used the same schematic for a STM32F2, and it connects successfully using JTAG.


Is there any difference/limitation with the STM32F7 MCU? Any clue of what can happen?


Thank you
