Matter: Pre Compiled Examples

[tejaChintalapati]

Hi,

I am trying to work on Matter light examples and tried to flash the firmware as it came. However, I am getting this error:

"[m[Kopening dependency file D:/WorkSpace/xxxxx/Nordic/NCS/v1.6.0-rc2/nrf/samples/matter/light_bulb/build_nrf52840dk_nrf52840/modules\nrfxlib\nrfxlib\nrf_security\src\mbedtls\CMakeFiles\mbedcrypto_base_vanilla.dir\D_\WorkSpace\xxxxx\Nordic\NCS\v1.6.0-rc2\mbedtls\library\psa_crypto_slot_management.c.obj.d: No such file or directory"

NCS Version: 1.6.0-rc2

Board: 52840-DK

Toolchain: 1.6.0

I just installed the NCS using the nRFConnect Windows application. May I know what's causing this and how to fix it?

Hello,

I just installed the NCS using the nRFConnect Windows application. May I know what's causing this and how to fix it?

It seems that there is an issue with the path length on Windows. Could you try to move your NCS installation to the top folder, i.e removing /WorkSpace/xxxxx/Nordic/ from the path, and seeing if this resolves the issue?
As far as I know the maximum valid path length on Windows is 260 characters, while the path in question is > 270.

Please let me know if this resolves your issue.

Best regards,
Karl

Hi Karl,

Thanks for your response. After moving the NCS to a different directory, this issue went away. However, a couple of new errors popped up.

Error 1: During rebuilding the solution, I'm getting this error:

Error 2: When I tried to flash (I know I shouldn't flash the solution which isn't building, but just wanted to see if any new errors may come), I got this error:

How should I move forward?

Hello,

unfortunately, Matter samples aren't available in NCS 1.5.1.

My apologies, I should have been more explicit here. In NCS 1.5.1 the matter examples are located in the connectedhomeip sample folder : v1.5.1\nrf\samples\connectedhomeip
The project's name change to Matter happened in the time after the release of v1.5, which is why it in v1.5 still uses the old name.
Please try the same example in v1.5.1, located in \connectedhomeip and let me know if you then face the same issue.

If the issue persists is v1.5.1 I will request an internal examination of this by our Matter development team.

Best regards,
Karl

Samples in NCS 1.5.1 compiled without a hitch!

Are there any additions/subtractions in features/functionality from 1.5.1 to 1.6-RC2 for matter examples?

Shall I wait for 1.6 to come and revisit this issue then?

Great, I am happy to hear that!

There are some general changes to the Matter framework inherited from the upstream Matter repository, which you can read about in the v1.6 Release notes. To my knowledge there is no difference in the application examples directly, so you may just as well begin developing your firmware with v1.5.1 and then upgrade to v1.6 once that releases.

Karl

Fantastic! I'll just get started with this and get my hands dirty.

Thanks for the help, Karl. Appreciate it.

No problem at all, I am happy to help! :)

Great! Please be advised that the Matter framework is still being developed, so there will be changes and new features / implementations along the way until it is officially released - but there should be no problem updating your application to make use of these as they become available.

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

Good luck with your development! :)

Best regards,
Karl
