STM32 cube programmer HEX file loading

[harshpanchal_6]

Hello Community,

I’m facing an issue while loading a firmware HEX file using STM32CubeProgrammer. The HEX file is not downloading successfully. Could you please suggest what might be wrong or provide guidance on how to resolve this?

This issue is usually not related to the HEX file itself but to configuration or connection problems. You may want to check points:

1) connection is ok ? make sure you selected the correct interface(st-link or uart or usb..)
2) mcu is powered ? if voltage is not detected, programming will fail.
3) if the mcu is protected RDP, can't programmed.
4) check your options bytes

Also please share the log output from the programmer.
