Cannot upload to STM32G030F6P6 with CUBEIDE and CUBE Programmer :(

[Sahiru]

Hi,

I have a STM32G030F6P6 connected to an STLink. I cannot upload at least an LED toggle code to the chip. I get the following messages in the CubeProgrammer. And I get "Cannot insert all breakpoints" error in the CUBE IDE.

I double triple checked my voltages. They are 3.3V. But still the messages from the Cube Programmer shows as 2.93V. Can you please comment on this and help me.

Hello, this processor is on your board or bought from some site?

I got many of these cheap board with processor locked with a bad cfg word, no idea why they do this. Symptom are unreadable processor and failure on erase like your report. From cube programmer read CFG register and look at value.

From your log programmer report Hardware reset, is reset pin connected? If not change to software reset and retry.

If this doesn't solve, connect reset pin then launch cube programmer and do a full chip erase. After that processor is unlocked and you can access.

I have the same issue with an stm32g030j6, the parts are original stm32 from trusted source.

The mcus were programmed before (no serial wire debugging pins were enabled), now when i want to programm them again i get a similar error than @Sahiru​ 

 I tried in CubeProgrammer Modes :

it turned out to be defective wiring, all works for me now
