Compile error in at_client example

[Hsu]

Hi Sir,

As follow the Getting start guide from nRF connect, I follow below command to get the latest example code.

-------
west init -m github.com/.../fw-nrfconnect-nrf
west update

cd <sourcecode_root>\ncs
pip3 install -r zephyr\scripts\requirements.txt
pip3 install -r nrf\scripts\requirements.txt
pip3 install -r mcuboot\scripts\requirements.txt
---------

I follow the step of "Set up a project in SEGGER Embedded Studio" to enable the project for "at_client".
But when run the compile, there is a fatal error show as below.

C:/SDK/ncs/nrf/drivers/at_cmd/at_cmd.c:12:10: fatal error: bsd_limits.h: No such file or directory

Build failed


If I comment #include <bsd_limits.h>, I can compile success.

The question is
1. Is the "bsd_limits.h" require for this project?
2. if this is file is require, how do I add the path in this project?

Thank you.

Hello Han,

This is most likely an error you get because you are in the master branch.

I would recommend that you instead try out a stable tagged release.

cd ncs/nrf
git checkout master
git pull
git checkout v0.4.0
west update

Then the sample should work without any errors.

Please check out this extensive tutorial on how to work with NCS for detailed information.

Hi Martin,

As follow the git command, I can compile success w/ v0.4.0 w/o modification, as follow the link, it should found the "merged.hex" and download in Target→Download File→Download Intel Hex File.

But I cannot find the "merged.hex" file.

So, I download the image (zephyr.elf) to DK board, but nothing happened. 

Do I miss anything?

Thank you.

BRs, Han

Please try to delete the build folder and then select 'build solution':

Hi Martin,

It works, thanks for help.

Thank you.

same issue,neither west build nor "build solution" in the segger thing produce a merged.hex.  The hex that's produced is also at the wrong position, overwriting the SPM, hence the crash.

the zephyr manual only mentiones that it will magically produce a merged hex, but doesnt tell you how it does it, so there's no way to know what to do when it doesnt work
