Stm32F030C8 Failed to Erase Memory Error

[JamesMoriarty]

Hi, I hope Everything is fine. I have a board that uses stm32f030 as the processor. When I open an empty project on stm32, debug or run it, I get the "failed to erase memory" error. I deleted the obtion byte from cubeprogrammer and changed the st link. It gives the same error again. What could be another reason?

Likely bad hardware, either the board or the programmer. Is this a genuine chip? Is this a genuine programmer? Can STM32CubeProgrammer program and erase the flash successfully?

[JamesMoriarty]

programmer and pcb are new. There is no such thing as being old. However, I can't delete it successfully from cubeprogrammer. Sometimes I delete it, sometimes it doesn't work. I also changed related cables.  also, I am using 1 uart and 1 spi channel. is it suitable to swap with stm32F072C8T6 ? When I look at the pins there is not much difference.

How is this relevant? Perhaps there is a language translation issue with new/genuine happening, so I will rephrase my questions:

 

Is the STM32 sourced from a reputable vendor? If not, it could be damaged.

 

Is the programmer an official programmer such as ST-LINK/V2 or is it a knock-off programmer? Knock off programmers can cause bad behavior.

 

General power issues or bad manufacturing could also be at fault, such as cold solder joints or an improperly designed board.
