Hello @khaaal​ 

I test it with using STM32CubeProgrammer v2.1.0, STM32F746G-DISCO and had no error, everything works correctly .

Could you please give me more details about the Title of the board (Discovery, Eval or Nucleo) to check the issue, also witch version of STM32CubeProgrammer have you used ?

Please send me your ETH_FINAL.elf file to check the problem.

Best regards,

Nesrine

34m25 is in the most ​current standalone update as I recall.

Check power supply, vcap, etc. Have adequate bulk capacitance.
