Is there an image compression option for DFU?

[loquat]

I try to DFU operation.

SDK15.3.0 / GCC / nrf52840

My application image size is 123,484bytes (nrf52module.bin)

I run command ,

nrfutil.exe pkg generate --hw-version 52 --sd-req 0xB6 --application nrf52module.bin --application-version 1 --key-file priv.pem app_dfu_package.zip

app_dfu_package.zip  size is 124,115bytes (may be not compressed)

I download 'nrfutil.exe' from https://github.com/NordicSemiconductor/pc-nrfutil/releases/tag/v5.2.0

Is there an image compression option for DFU?

Hi,

We do not have support for image compression in our current bootloader, unfortunately. You may want to evaluate third-party compression libraries such as this one: https://github.com/korczis/ucl if you're going to implement it yourself.

Oh, It is a pity.

Thank you.
