I changed the microcontroller from STM32F733ZEI6 to STM32F723ZEI6 and it stopped working.

When connecting with the debugger (STM32FcubeIDE)

・STM32F733ZEI6 was able to connect.

・STM32F723ZEI6 was disable to connect. and The following error occurred(Details are attached).

Error: failed to download Segment[1]

Error: failed to download the File

What should I do?

Hello @HINOU.1​ and welcome to the STM32 Community :smiling_face_with_smiling_eyes:

It seems this is known issue with the latest version of STM32Cubeprogrammer V2.6.0

Our team is very aware of this problem, and working to resolve this.

Same issue is reported in this post and resolved by using previous version of STM32CubeProgrammer 2.5.0.

Could you please try with the version 2.5.0, you can download it from ST web page.

Then, please keep me informed with your progress on your issue.
