Hello,

Please refer to the below article on details regarding to the descriptors. The DSCR.A51 file has to be modified to suit the endpoints that you have initialized in your application firmware.

In case you are comfortable sharing your firmware source code on the community, we shall look into it and suggest the changes.

Best regards,

Hello,

- Please check if you have modified the descriptor information from the DSCR.A51 file.

- Also, what is the boot mode you are using. Is it RAM or EEPROM? And, are you switching the device to boot-loader mode before loading the new firmware?

Best regards,
