Hello Abdelhadi,

By seeing the log you shared it can be understood that it's failing to establish the connection to the target. There could be multiple reasons for this like damaged device, wrong configuration file, power connection issues, wrong parameter etc.

As first step, you can check if power supply is stable and the device is not in reset state.

If there is no issue with respect to power, then you can try to erase using Auto Flash Utility tool and try flashing. In order to download Auto Flash Utility tool, please first register yourself to MyInfineon platform. The steps to follow to get access to our documentation and software tools can be found in below link:

Please try the initial steps suggested and let us know your observations.

 

Thanks,

Kavya
