BUG: STM32CubeProgrammer in DFU/USB mode with elf file flash is not able to start app.

[kareled]

Hello,

I've installed STM32CubeProgrammer 2.17.0 on Windows 11. I'm using it for flashing customer board using DFU mode over USB. I'm flashing elf file so cube programmer should be able to grab start address from it. For flashing I'm selecting 'Run after programming' but leaving 'Start address' box empty. In fact I'm not able to modify content of this box anyway.

Now, when I flash by clicking on 'Start Programming' button I see following output:

  18:20:25 : Memory Programming ...

Unfortunately my application is not started. To start it I need to switch board off and on again. Anyway, also my ELF file suggest (output below) that starting address should be 0x8008001 and not as programmer claims in output above 0x8000000. Now my question is if this is a know issue or not or how is it possible to work around the issue.

Thanks!
Karel

Hello @kareled,

To fill the "Start address" box, you can use a .bin file instead of an .elf file.

Additionally, I tested a LED example using DFU with the Nucleo-F412ZG, and it worked fine (the application started and then disconnected from the device).

Could you please send your option bytes configurations using this command: 

$STM32_Programmer_CLI.exe -c port=SWD -ob displ

Thanks, Amine.

You create dupl thread and some teory info. GO command in utility or from code read start address from location entered as vector table base and start address is stored on first 32 vector. Then utility read 8008000+4 and get 32 bit number for jumping... realy impossible 8008001 ...
