DFU insufficient resources

RE: DFU insufficient resources

Hi, the file I use to generate the package is created when I do "make" in my project folder so it's not merged.

The size of the nrf52832_xxaa.hex file is 959 KB, and the app_dfu_package.zip is 342 KB. I'm trying to reduce them because I have a file which contains 13 arrays of pictures (80x160) I want to display. So I need to save them into the flach memory but I can't because it's too big, so I have to find another solution.

So the "nrf52832_xxaa.hex" file you use to generate app_dfu_package.zip is not merged .zip with the Softdevice or bootloader?

What's the size of the application when you build it in SES?

I don't understand what you're saying. The package I create is my app + my private key. It is this package that I upload on my phone.

Hi,

Each image must be provided separately when you generate a DFU package with nrfutil. I.e., you can't merge images beforehand.

Creating a SD+BL update:

nrfutil pkg generate --softdevice <softdevice>.hex --bootloader <bootloader>.hex ...

Hi,

thanks for your answer.

I build "nrf52832_xxaa.hex" from my project with the command make.

I program softdevice with this file: s132_nrf52_6.1.1_softdevice.hex, bootloader with bootloader_dfu.hex which is created like this mergehex -m ..\..\..\..\..\components\softdevice\s132\hex\s132_nrf52_6.1.1_softdevice.hex _build/nrf52832_xxaa_s132.hex -o bootloader_dfu.hex

Hi Lydie,

Did you build "nrf52832_xxaa.hex" from one of the BLE SDK projects? Also, do you know if the application is actually supposed to be around ~340K? That's a big application for this chip variant.

Note that the application shall not be merged with bootloader or Softdevice when you generate DFU package.

Best regards,

Vidar
