There are two different ways to program and debug the onboard STM32 MCU:
•
Using the embedded STLINK-V3E
•
Using an external debug tool

Embedded STLINK-V3E
6.1.1
Description
The STLINK-V3E programming and debugging tool is integrated into the STM32H7B3I-EVAL Evaluation board.
The embedded STLINK-V3E supports:
•
5 V power supplied by the CN21 USB connector
•
USB 2.0 high-speed-compatible interface
•
JTAG and serial wire debugging (SWD) specific features:
–
3 to 3.6 V application voltage on the JTAG/SWD interface and 5V tolerant inputs
–
JTAG
–
SWD and serial viewer (SWV) communication
•
Direct firmware update feature (DFU) (CN25)
•
MIPI10 compatible connector (CN16)
•
Status COM LED (LD9) which blinks during communication with the PC
•
Fault red LED (LD8) alerting on USB overcurrent request
•
5 V / 500 mA output power supply capability (U19) with current limitation
•
5 V enabled green LED (LD7)

How to use
It is very easy to use STLINK-V3E to program and debug the on-board STM32.
1.
Verify that the jumper JP29 of Power Supply Sources is correctly set. (Refer to
).
2.
Connect the board to a PC with a USB Type-A to Micro-B cable through the USB connector CN21.
