I encountered an error while programming my STM32 microcontroller using ST-Link Utility. The exact error message is "The ELF loader sector erase function fails." Can you help me troubleshoot this error?

 

Was the chip preprogrammed?

 

Was the chip preprogrammed?

No, I am first time program the microvcontroller (I mean it's new).

 

Where did you buy the chip?

 

Where did you buy the chip?

I bought it from IndiaMART (Thirumalaivasan Technology).

 

Is it possible that the IC is fake?

 

No, I

Is it possible that the IC is fake?

No, I checked the continuity of the GND pins.

 

No, I

No, I checked the continuity of the GND pins.

My physical microcontroller shows the part number STM32F412RET6, but when I connect it to the STM32 ST-Link Utility through ST-Link V2, it identifies the device as STM32F401xD/E. What is the exact problem?

Looks like a fake IC.
