Custom board SWD Programming

Hi there,

We're designing a custom board for a customer with the STM32F746 DSP and we wanted to remove the external programmer so it would be easier for them to upload and debug their own code. In order to do this, we copied the schematic from the Disco board using the SWD connection.

When connected through USB, the PC detects the board as the ST-LINK programmer, but it's version 2/0 which only works with JTAG. Is there a way to change it to V2/1 to support SWD ? Or how can we do this?

Best regards,

Luis

Using a stand alone ST-LINK we can program the main (746) mcu. When using the onboard programmer, it says that it needs a reset. If we hold the reset when trying to program, it fails to connect.
