STM32CubeProgrammer cannot start a program after writing it to flash from an .hex file

[FValm.1]

Hello! I'm using a nucleo board with STM32F411RE MCU. I can connect to my board in DFU mode and program the flash with an hex file but it seems impossible to write a specific start address (0x08000000) to run the program after it is programmed in flash. That doesn't happen with .bin files where I can set the correct start address. Is there any reason for that strange behaviour?

Hi @FValm.1​ ,

Can you please share the hex file used ?

This is just an example... I would like to highlight that the problem concerns the possibility to modify the start address field in STM32CubeProgrammer. That field is grayed/disabled when you program an HEX file while it is modifiable when you program a BIN file... Is there any reason for that?

Thanks!

Hi @FValm.1​ ,

The specificity of Hex file compared to bin file is that address is already defined in file so you don't need to modified it in STM32ubeProgrammer start address field.

Hex file contains both address and application code.

Hi @Houda GHABRI​ ,

I have understood your answer but why, if start address is contained in the HEX file, then the program fail to start?

I get the following error in the log of STM32CubeProgrammer:

Do I have to specify something to the builder to include the start address in the hex file?

Should be consistent with the Reset_Handler entry point.

I'd score this as a FAIL for STM32 Cube Programmer

The entry point is specifically called out in .ELF and .HEX ​files.

Based on the data it shouldn't be hard to make a reasonable determination from a .BIN, but it is not explicitly called out.
