ncs build(pristine) process taking longer time

[tchag]

Hi

1. Longer build(pristine) time

                   When trying to build the application on vscode, the build(pristine)process is taking more than 5min during each time. Is this the expected ideal build time. If YES, is there a way to reduce the build time

System(PC) Specs: 

Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz   2.90 GHz

RAM: 16.0 GB 

OS: Windows 10 Pro

Dev Env

VS Code, ncs-v2.0.2, 

nRF connect App: v3.12.0

Tool Chain Manager: v1.1.3 

Build cfg settings:

Board: nRf5340dk_nrf5340_cpuapp_ns

Debug : Enabled

this is the the prj.conf file which I'm using

2. Issue with generating system report using nRFConnect App(Windows)->Tool Manager->About

I have seen on devzone mentioned to share the system report which is generated from Toolchain, but when I tried, the report was never generated even after leaving the tool open for more than 2hours. It says "generating system Report..."

Hello,

Yes, the pristine build option can take a couple of minutes to complete since this builds the entire project again from 'scratch'. Fortunately, you can use the regular build option (non-pristine) whenever you just have made changes to your source files.
I.e it is only really when you have made changes to the input files (such as prj.conf/Kconfigs/devicetree files) that you need to use the pristine build option. In this case, it is required to use the pristine build option in order for your changes to the input files to be taken into account. 
The regular build option should complete much faster! :) 

Best regards,
Karl

sure.. thank you

I do have a another question reg debugging using vs code.
1. Does it require any additional tools to be installed beacuse when i click on debug majority of the time the device gets disconnected and have to restart the debug process

and

2. also not able to restart the debug. Always have to suspend the current operation and have to start again

[tchag]

1. Yes I did install the and nRF command Line tools sdk using Toolchain manager and as well VSC code extension by pressing 'open VSC' in the toolchain manager tab)

But if I remember correctly I have disabled cmake  VSC code extension when it prompted to disable. Will this cause an issue

2. When I try to restart the debug service after executing couple of minutes, the device automatically gets disconnected. - Cortex debug v1.6.3


I followed and installed v1.6.0 for cortex debug - havent faced the issue this morning, but will keep looking if I face such issue
RE: VSC debugging stops working with GDB major version error

Hello again, tchag

Thank you for your extreme patience with this. I have been out of office for some time, but now I am back.

Do you still require technical support with this issue, or has the issue since resolved?

Best regards,
Karl

Hi,
I have tried the build on another laptop it did build fast but the PC I'm using outreach specs when compared to the laptop but not sure why the build is taking longer time.

When I tried to generate system report on nrf connect desktop(toolchain Manager) application, no report is generated, it just says 

is it due to installation error or the system report feature is broken (since I have updated the toolchain twice in this period)

Hello tchag,

Could you detail roughly how long the pristine build is taking in both these cases?
A couple of minutes is to be expected for a large project, since it will recompile the whole project. It also depends on the specs of your laptop, as you mention.

tchag said:

Did you turn on the verbose logging in the 'about' pane of the toolchain manager prior to generating the report?
If not, the report could be pretty sparse if everything completes successfully.

Best regards,
Karl

Build Time - Laptop

non-secure build -> under 2min

secure build   -> 40-50sec

Build Time - Desktop

non-secure build -> 5 min (4min 56sec)

secure build   -> 3min 15sec 

 
the report generation (Desktop)worked after updating the toolchain manager. Here is the report generated (Desktop)

Thank you for providing the information and build-times.
It seems strange to me that the build takes longer on the desktop compared to the laptop, but both I would say that both buildtimes are within the 'couple of minutes' that is to be expected when performing a pristine build.

It should be noted that you usually do not need to perform a pristine build, so your usual time building the project every time you have made a change will be far lower than this. The regular build action checks which files that have been altered, and which of their dependencies that needs to be updated, and compiles only those. Thus, when you are developing your project code, and doing a lot of incremental builds, you usually will finish the build in < 1 minute, as opposed to the pristine build (which rebuilds the entire project and all its dependencies).
Pristine build is really only needed when you have made changes to your input files (kconfig/prj.conf and devicetree files, primarily).

Best regards,
Karl

[tchag]

Thank you for comprehensive explanation.

Yes I do the pristine build when there is changes to the input files. and yes during the regular build (during dev) the build times are < 1min

Thanks

Hello again, tchag

No problem at all - I am happy to help, and glad to hear that you are seeing < 1 minute build times for incremental builds! :) 

Please do not hesitate to open another ticket if you should encounter any other issues or questions in the future.

Good luck with your development!

Best regards,
Karl
