How to program/flash STEVAL-BLUEMIC-1

[SHack.1]

How do I flash the STEVAL-BLUEMIC-1 board? The STEVAL-BLUEMIC-1 board came with a 5 pin SWD programming cable. What does this interface with? Is there an ST Link tool that connects to the SWD cable and a USB port on a computer?

Hi @SHack.1​ ,

you are right, the 5 pin JTAG /SWD cable has to be interfaced with an ST Link programming tool. For example, the STLINK-V3 debugger has a direct connection for this cable. If you don't have this tool, you can use any NUCLEO board, which is equipped of the SWD termination.

In both cases, the suggested interface for the programming is the STM32CubeProgrammer.

Thank you so much for your quick response. I will purchase the STLINK-V3 debugger.

I have connected the STEVAL-BLUEMIC-1 board to the STLINK-V3 debugger using the SWD cable (see below).

 

I am using the STM32CubeProgrammer software. I updated the firmware on the STLINK-V3, and the power light is green and the COM light is red on the STLINK-V3. The STEVAL-BLUEMIC-1 board is powered on. When I click the "Connect" button, I get the following error.

  

How can I resolve this error?

Hi @SHack.1​ ,

Uhm... I have some question for you:

• Can you check the voltage on the T_VCC pin? And did you disconnect the Li-ion battery before running the upload?
• Can you please also check that the SWD cable is connected in the right orientation?
• Did you do the full chip erase before the firmware upgrade?

Hi @Eleon BORLINI​ 

• I tried to connect to the BLUEMIC board with and without the Li-Ion battery. Below are my error logs and the value of T_VCC for each case.
  • BLUEMIC with battery connected and powered On
    • T_VCC=2.19V
    • Error log:

• BLUEMIC with battery connected and powered Off
  • T_VCC = 0V
  • Error log:
• BLUEMIC connected without the battery
  • T_VCC = 0.001V
  • Error log:

• The SWD cable is connected in the right orientation. The CLK, GND, and DIO pins on both the BLUEMIC board and STLINK board are connected.
• By full chip erase, do you mean on the STLINKV3 board or on the BLUEMIC board? I did not erase anything on either boards.

Here is a screenshot of what the STM32CubeProgrammer looks like.
