Error: Data mismatch found

Good afternoon dear collegues!

When I try to compile and upload my program through the CubeIDE I have the following problem:

Error: Data mismatch found at address 0x080003C0 (byte = 0x1B instead of 0x1A)

Error: Download verification failed

Every time the byte is different. I use Stm32F072CBT6 MCU and Stm32F030C8T6.

I try to programm it with StLink board

Now on my board the Boot Pin (Boot -- 10k -- GND) and NRST pin (NRST -- C -- GND) are connected only.

Is this problem connected with CubeIDE?

More apt to be a device or power supply issue

Hello @MMudr.1

First let me thank you for posting.

Did you checked the hw like @Community member mentioned?

I want to suggest if you try to flash the MCU with CubePorgrammer.

Kind regards,

Semer.
