Debugging NUCLEO-H723ZG

[erastusC]

Does any one know if this board can be debugged via the USB port that is connected to the PC or does one require an external debugging link?

If external is required which one would you guys recommend I do have ST-LINK V2 which I use for smaller boards.

Would like to know what is recommended.

Hello @erastusC ,

There are two different ways to program or debug the on-board STM32H7 MCU:
• Using the embedded STLINK-V3E, connect PC to CN1 USB.
• Using an external debug tool connected to the MIPI-10 connector (CN5)

I advise you to follow the methods described in the UM2407, in "6.3 Embedded STLINK-V3E", 

and "6.3.3 Using an external debug tool to program and debug the on-board STM32H7" sections.

Check and configure properly the jumpers and solder bridges, for that you can follow the recommendations in the "6.7 Solder bridges and jumpers" section.

Review the picture of the board, the 1x1 cm chip at the North End of the board is an ST-LINK/V3, this provides for primary debugging and a VCP that connects to one of the H723's USART's
