STM32L151 flash hex file to internal eeprom over ST-LINK

Hello everyone,


we are currently developing our production/test equipment for automated production of a STM32L151-based device.

In the production process, the STM32L151 is already flashed via a ST-Link (V2) programmer.

In order to identify each device, a serial number is generated and shall be written into the internal eeprom of the device.

We would like to utilize SWD for this purpose.

When testing the ST-Link V2 with ST Utility Software, I have not been able to write a hex-File to 0x08080000, which should be the internal eeprom memory address. Please correct me if I am wrong.

Can you tell me if this is possible and if so, how ?


Thank you very much for your help.


Best regards
