• EVALUATION BOARD
  • (EVAL-SCS007V1)

NUCLEO FW upgrade

1. Connect the NUCLEO-C071 (or NUCLEO-F072) to the laptop using USB-C cable
2. Please make sure the device drivers are installed successfully.
3. Download and install STSW-LINK007
4. Select your operating system and run the STLINKUpgrade.exe to upgrade the NUCLEO-C071 (or NUCLEO-F072).
5. Select the STM32 Debug+Mass storage+VCP option
6. Case 1:
   1. Using EVAL-SCS007V1: Power the board from the NUCLEO
   2. By default, JP1 and JP8 are in external position: STUSB4531 is powered by USB-C port (VBUS)
   3. Set JP1 and JP8 in internal position: STUSB4531 is powered by Nucleo board
   4. Explanation: In order to access to STUSB4531 NVM or I²C registers from the NVM flasher or a GUI, the STUSB4531 must be always ON, even if the STUSB4531 is not attached to a source. That’s why, STUSB4531 power supply must come from the system, and not from VBUS
7. Case 1:
   1. Using EVAL-SCS007V1: Connect to the NUCLEO and to the laptop
8. Case 2: Using EVAL-SCS006V1: Connect to the NUCLEO.
   1. Please make sure SDA and SCL signals from the STUSB4531 board are properly connected to their counterpart from NUCLEO-C071B / NUCLEO-F072RB
9. Case 2:
   • Using EVAL-SCS006V1: Power the board from the USB-C port
   • Explanation: at the opposite of EVAL-SCS007V1, EVAL-SCS006V1 is powered from VBUS exclusively.
   • In order to access to STUSB4531 NVM or I²C registers from the NVM flasher or the GUI, the EVAL-SCS006V1 must be attached to a SOURCE (A to C cable, power bank, AC adapter, docking etc.)
10. Download the STUSB4531 GUI package by searching STSW-STUSB020 from the www.st.com homepage.
11. Then click on “Get Software” from the bottom of the page
12. Download will start after accepting the License Agreement, and filling contact information.
13. Save the file stsw-stusb020.zip on your laptop and unzip:
14. The STM32 Nucleo board must be flashed with the correct binary file contained in the bin directory.
15. Connect the Nucleo board to the Laptop (see 7 or 9 ) Drag and drop the appropriated BIN file to the Nucleo board (NODE_C071RB or NODE_F072RB)
16. Press the NUCLEO-C071RB “RESET” button (B2 – Black push button).
17. If using the EVAL-SCS007V1, the LED LD5 should be blinking (see 7)
18. The board is now configured to act as a USB to I²C bridge between the STSW-STUSB020/1 and STUSB4531.
19. Click on the STUSB4531_GUI.exe file to open the GUI. The following window must appear.
20. Select the correct COM port in the “COM settings” section:
21. NB: The GUI can also be used in OFF-LINE mode, ie. without being connected to STUSB4531.
    • In this case, no ST LINK is detected on the computer’s COM ports.
    • The “NVM Configuration” panel can be accessed to modify / create a STUSB4531 configuration and generate the NVM file.
