24 MHz Crystal Oscillator

Debug

• JTAG/SW 10-pin TAG probe TC2050-IDC-NL
• ST-Link USB-C

The STM32H7S78-DK Discovery kit integrates an STLINK-V3EC embedded in-circuit debugger and programmer for the STM32 MCU, with a USB Virtual COM port bridge and comes with the comprehensive MCU Package.

Getting start

1. To identify correctly all device interfaces from the host PC, install the Discovery USB driver available on the STM32H7S78-DK webpage, before connecting to the board.
2. Check that the jumper JP5 is ON and JP1 is set on STLK. Black switch SW1 is set to 0.
3. Connect a USB Type-A or USB Type-C® to USB Type-C® cable (not included) from the STM32H7S78-DK Discovery board (CN7) to a PC to power the board. The LEDs LD10 (5V power), and LD7 (COM) light up.
4. The LCD module displays a welcome menu, indicating the startup of the demonstration application software.
5. The demonstration application software and its user manual, as well as other software examples for exploring STM32CubeH7RS features are available on the STM32H7S78-DK webpage.
6. Set JP3 ON to keep STLINK-V3EC in reset mode. It is useful to reduce current consumption for user USB certifications.
