Title: Convert .bin firmware to dfu file
Post by: arcticsilver on 27. April 2021, 17:13:56

Hi all,

I'm trying to convert a .bin firmware file for an OVI40 F7 (Sparrow) to a .dfu file but I don't know the 0x address to do the conversion. Any help would be appreciated!

Hi

Fw upload from address 0x8010000, loader from 0x08000000. 73!

I wonder if when using ST-Link to load MCU STM32F437VIT6TR, should the starting address be 0x08010000 ?

Instead of 0x08000000 ??
Thanks,
Chuck

Bootloader starts at 0x08000000
Firmware starts at 0x08010000

Bootloader only uses (the first) half of the space. The second half is "virtual EEPROM" inside STM32.

Can't you load both at the same time, with one .bin file??
A program image?

Nop. You would overwrite "virtual EEPROM" which contains all your personal settings (or a backup of them).

No, I mean a blank new mcu,

For a blank new MCU you can assemble the two .bin-files to one "big" starting at 0x08000000.

EDIT:
But it is not simply merging the two files. You have to add 0xFFs behind the bootloader to fill the space where the virtual EEPROM resides.
