Upload firmware to specific address

1

Hi, folks.
I work with STM32F429ZI and PlatformIO on QtCreator, and i need to upload firmware to specific address like 0x08020000 for example. And I can’t find in docs on platformio which key for upload_flags I can use for it, or how I can modify upload_command for it. Thanks.

The builder scripts in platform-ststm32/main.py at develop · platformio/platform-ststm32 · GitHub respect the upload.offset_address from the board’s JSON definition file.

Yours is here

Accoring to docs you can also try and add to the platformio.ini something like

board_build.upload.offset_address = 0x08020000

Use pio run -t upload -v or “Verbose Upload” to verify that the flasher command contains the correct upload address.

board_build.upload.offset_address = 0x08020000 doesn’t work.
I think that modifying MBED board’s JSON definition file not good idea

Can you give your platformio.ini and the log of the aforementioned verbose log?

Are you talking mbed-os?

You can also create a folder called boards/ and create a new board definition there. See docs.

I found right solution for me. It is add mbed_app.json to your project root with:

{
    "target_overrides": {
        "*": {
        "target.mbed_app_start" : "0x08020000",
        "target.mbed_app_size" :  "0x000A0000"
        }
    }
}

This parameters expand to:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x8020000, LENGTH = 0xa0000
...
}

on your .ld script and you don’t need to change upload_flags and upload_command.

Yes, sure.

sorry, I mixed up “mbed” and platformio files.

Does mbed_app_size represent the maximum size of my app code can be?
