Board support for NRF52840-CKAA-R7 in nrf connnect sdk

[Priyesh Shahi]

I am currently working on a project to migrate to the nRF Connect SDK. We are using the NRF52840-CKAA-R7 package of the nRF52840. However, I have not been able to locate the appropriate settings for this package in the nRF Connect SDK within Visual Studio Code.

I am seeking assistance in determining whether there is existing board support for the NRF52840-CKAA-R7 package in the nRF Connect SDK. If such support is not available, I would need guidance on how to create a board configuration file for this package.

Hi

Please see my college reply below from this case 

"

Only the pin configuration is different between the QIAA, QFAA and CKAA.
Some of these have more pins than others.
If you use a pin number higher than what is available, this will cause errors.

As long as you are aware of this constraint, you can use the Zephyr QIAA configuration for the other package types as well.

Hi Runar,

Thank you for the information.

I understand that the pin configuration is the main difference between the QIAA, QFAA, and CKAA packages and that using a pin number higher than what is available can cause errors.

But I have to create a custom board configuration for the CKAA package. Could you provide guidance or resources on how to go about creating this custom board file in the nRF Connect SDK? because this is the starting point in nrf connect sdk to build any project.

Thank you for your assistance.

Best regards,
Priyesh

Hi

For creating a custom board I would reefer to the lesson 3 on the nRF Connect intermediate course. Which NCS version do you intended to use for your project? The reason why I am asking is that we released the NCS v2.7-rc1 last week, which often hints that a new NCS release is around the corner. This release candidate also includes the change upstream Zephyr has implemented in terms of custom board where they changed the hardware model. If possible I would consider waiting a week or two on creating the custom board, or maybe starting with NCS 2.7.rc1 since the change to custom board might take some time to fix. The NCS course is not yet updated with the new hardware model.

Hi,

I am currently using NCS v2.5.1 and am willing to wait for the next release. Could you please inform me how I can stay updated about the upcoming releases?

Thank you for your assistance.

Hi you don't need to wait as the release candidate it out. We also have documentation here regarding how to port an custom board. 

I think the easiest way would be to go to https://github.com/nrfconnect/sdk-nrf -->watch --> custom and select release to be notified regarding new releases
