How to reduce the size of the merged.hex file?

[Learner]

Hello,

I am trying to find ways to reduce the size of the output hex file merged.hex.

I am using the following hardware and development tools.

- nRF52833 SoC

- Zephyr OS build v2.6.99-ncs1

- Segger Embedded Studio Nordic Edition

  Release 5.60  Build 2021081102.47262
  Nordic Edition
  Windows x64

- I am already using the following configs in prj.conf file to reduce the size of the merged.hex file

  CONFIG_MINIMAL_LIBC=y

  CONFIG_SIZE_OPTIMIZATIONS=y

The project config file prj.conf is attached.

Thank you.

Kind regards

Mohamed

Hi,

There are some guides available, that focus on reducing the image size.

Good Morning Qarnet,

Thank you for your reply and the info provided. I have the feeling that I may be enabling some configurations in my prj.conf file that I needed earlier in the project life but not anymore. I will look at my prj.conf file closely.

Kind regards

Mohamed
