Using Segger Embedded Studio and Zephry for nRF52840

[craig.goldman]

Is there an example for setting up a Segger Embedded Studio project for using an nRF52840 with Zephyr.  The instructions on the Zephry site for adding Zephyr files to a project build do not seem to apply to how SES sets up a project.

Hi

We're painfully aware of this matter. Can you copy the error SES outputs when you try to open the nRFConnect project?

Best regards,

Sorry if I caused some confusion.

By following your suggestion, I've gotten beyond opening the nRF Connect project.

I have a trouble when I try to build the project.  The problem occurs deep within building Zephyr.

I get the following in the output log...

1> Combining ‘zephyr/include/generated/offsets.h’
1> Traceback (most recent call last):
1>   File "C:/Users/info/Dropbox/64Seconds/NHM5G-Z/zephyr/scripts/gen_offset_header.py", line 72, in <module>
1>     input_file = open(args.input, 'rb')
1> FileNotFoundError: [Errno 2] No such file or directory: 'C:/Users/info/Dropbox/64Seconds/NHM5G-Z/build/zephyr/CMakeFiles/offsets.dir/arch/arm/core/offsets/offsets.c.obj'
Build failed

"C:/Users/info/Dropbox/64Seconds/NHM5G-Z" is the base directory for my nRF52840 project.

Perhaps interesting is that this error looks identical to one reported in Case ID: 223311, although the reported circumstances seem totally different.  I posted a similar comment yesterday in that case.

My concern is that I have no way of knowing why the file is not available.  I presume it needs to be built by emStudio, but I do not know why this build did not occur.

Any help would be appreciated.

I just noticed that I failed to copy an important line in the log

Rebuilding ‘zephyr/include/generated/offsets.h’ from solution ‘build’ in configuration ‘Common’

Hi Craig

Did this solve what you were struggling with, or are you still having trouble? It is not clear to me.

Best regards,

Simon

Still having problems.  SES build of project fails when trying to execute "Rebuilding ‘zephyr/include/generated/offsets.h’ from solution ‘build’ in configuration ‘Common’".  Log information is above.  Not sure if this is a problem with emStudio, the Zephyr files, the structure of the Zephyr source directories or something else.

As I noted in earlier posts.  There appears to be no documentation how to create a new project for an NRF52 or NRF91 that includes the Zephry directories.  I followed the Zephyr documentation for adding the Zephry directories into the project, and I followed Nordic documentation for a new emStudio NRF Connect project.  There is still a need to inform emStudio about the Zephyr build.  I presumed this is done by creating a CMakeLists.txt in the top-level project directory.  That seems to work- partially.  Some of Zephry builds but (as seen in the log information above), the build eventually fails.

As I noted yesterday, I fit it interesting that this error I am getting looks identical to one reported in Case ID: 223311, although the reported circumstances seem totally different. 

I do not know how to proceed.
