"Error: Data mismatch found at address..." while debugging

[RakeshGajjar]

Hello ST Team,

I am using STM32CubeIDE and working on STM32F072R8T6 MCU. I am not able to debug my code. Same code was working fine till few days.  But now it give  me follow error

Error: Data mismatch found at address 0x08001D99 (byte = 0x60 instead of 0x68)

Error: Download verification failed

Encountered Error when opening C:\ST\STM32CubeIDE_1.18.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.2.100.202412061334\tools\bin\STM32_Programmer_CLI.exe

Error in STM32CubeProgrammer

Shutting down...

Exit.

Please help me for the same. The error screen shot is as attached.

Best Regards,

"Verification" is where the programmer reads-back the data from the MCU, and checks that it matches the file that was down loaded.

The message tells you that this check failed: it found the byte value 0x60 at address 0x08001D99, but that address should contain the value 0x68.

Something must have changed ...

Thanks Andrew for prompt response.

I am using STM32F072R8T6 MCU with inhouse develop board for UPS Display application. 

I am using SWD debugging Interface and ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32

The source code is same and no changes has been done.

It was working before and now i am not able to debug the same.

Please guide me.

Best Regards,

So you need to show the schematic; again, please see: How to write your question to maximize your chances to find a solution

Is it genuine ?

Can it still program other targets?

possibilities for noise & damage?

Hello Andrew

Tried the same code on another PC and it works fine. Now suggest me what should i do. Should i unistall the STM32CubeIDE and reinstall it again on problematic PC or any other suggestion ?
