Hi,
I am designing a custom PCB with an STM32H723. To programm it, i bought a brandnew ST-Link v3 MINIE. CubeIDE reads the serial number of the V3 but can not connect to the target.
- Target is supplied with VCC.
- From the Board-to-Board-Connector after a lengthy search i connected TMS to SWDIO, TDI to SWO. RESET, CLK, GND and VCC where obvious.
- BOOT0 i connected to GND.
- Config as follows:
starting debuging i get this return:
[EDIT: solved sidequest] Searching for solutions i found the programm ST-Link Utility and wanted to start by updating the firmware but the V3 gives me a communication error.
When i klick ok, sometimes a version is read and the "Yes" button for upgrade is enabled. But when i klick it i get another error:
I tried a different V3MINIE even a new USB-cable for this.
[EDIT: Solution for the sidequest] Use the upgrade only software named ST-LinkUpgrade.exe : https://www.st.com/en/development-tools/stsw-link007.html
My question: what am i missing?
