Hello,
Until yesterday I was able to connect my ST-LINK V3SET via SWD to my STM32F411E-DISCO board without any problems. My setup is the STM32 extension for VSCode, where I debug using the STM32CubeProgrammer CLI. Everything was working fine, but now when I try to flash the program, the target is not detected. The log shows:
ST-LINK FW : V3J16M8B5S1
Board : STLINK-V3SET
Voltage : 0.00V
Error: Unable to get core ID
Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication
If I open STM32CubeProgrammer, I also cannot connect to the board when pressing Connect. However, I found that if I select Hardware Reset, the connection works, and if I perform a full chip erase, flashing from VSCode works (although very slowly). On the second attempt, it fails again.
The log always reports the voltage as 0.00V, which should not be the case. I have already tried changing the power supply and USB cables, but nothing changes.
Any ideas on what could be causing this? Thanks.
