How can I write the cmakelists and generate the hex file for bootloader?

[ZHENGXIANG]

Hi,

I try to use cmake in Linux to get the hex file fo bootloader. The Platform is nrf52832_xxAA, the toolchain is gccarmemb. I read the given cmakelists but many variables have not been defined already and as a result, I cannot generate the hex file. 

As you can see in the code, except the bootloader, other variables like platfor source code does not set.

So, what are the definitions for these variables and how can I know them?

Before answering your question I would like to ask why you are using NCS for the nRF52832? We mainly give support for questions where nrf52/nRF51 devices are used along with the nRF5 SDK. Is this choice intentional? 

You could also ask for help in the Zephyr mailing list or join the #zephyrproject IRC channel."

Best regards,

Simon

I cannot understand what you say. Because all of my screenshot is from nRF5 SDK for MESH file. You can find these code in \nrf5SDKforMeshv320src\mesh\bootloader\cmakelists.txt.

The following document is the cmakelists:

I cannot use this cmakelists to generate the hex file, could you please give me the correct cmakelists?

[Simon]

Okay, my fault. I was mixing it with the NCS, where CMake is used everywhere. I'll look into your issue.

Best regards,

Simon

I have correctly installed all the tools which shows in the given document: Installing the toolchain (for Linux). The only thing I do in the cmakelists is adding 

project(bootloader)

cmake_minimum_required(VERSION 3.9)

to the top and make it work.

I also follow the steps in Building the mesh stack and examples.

However, the official file seems to be incomplete and cannot generate the hex file. In the path \nrf5SDKforMeshv320src\bin\bootloader\gccarmemb, I find the correct hex file. I want to generate these hex files from the cmakelists given by Nordic and I cannot do that. There must be some problem with the cmakelists so could you please show me the correct one?

[Simon]

Could you continue the discussion in this thread?

Simon
