STLINK-V3E firmware upgrade
The STLINK-V3E embeds a firmware upgrade mechanism for an in-place upgrade through
the USB port. As the firmware might evolve during the lifetime of the STLINK-V3E product
(for example new functionalities, bug fixes, and support for new microcontroller families), ST
recommends keeping the STLINK-V3E firmware up to date before starting to use the
STM32H7 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com

Using an external debug tool to program and debug the on-boards
STM32H7
There are two basic ways to support an external debug tool:
1.
Keep the embedded STLINK-V3E running.
Power on the STLINK-V3E at first until the COM LED lights RED. Then connect your
external debug tool through the MIPI-10 debug connector (CN5).
2.
Set the embedded STLINK-V3E in the high-impedance state:
When the STLK_RST jumper (JP1) is ON, the embedded STLINK-V3E is in the
RESET state, and all GPIOs are in high impedance. Then it is possible to connect the
external debug tool to the debug connector (CN5).
