nRF52805 sdk_config.h file

acanidio over 5 years ago

Good morning,

I'm developing an application for nRF52805.

I saw that in SDKFolder/config there are all "complete" sdk_config.h files for all nrf52 targets except for the nrf52805.

Is it correct to copy the complete nrf52810 folder as nrf52805 and assume that folder is correct or does it need some modifications?

Best regards,

Andrea

yes, the sdk_config.h should also work for nRF52805. Please let me know if you see any issues. -Amanda H.

Hi Andrea,

What version of SDK are you using? You need to check that nRF52805 support requires the latest SDK as noted in the compatibility matrix here SDKs and SoftDevices.

Mostly the nRF52805 has a subset of the functionality in the nRF52810, so it might be possible if the SD supports nRF52805. This post and this tutorial Developing for the nRF52805 with nRF5 SDK might help.

We are targetting the latest SDK, version 17.0.2, since the SDK 17.0.0 mentioned in the blog post in no longer available.

Hi Andrea,

SDK 17.0.0 is replaced by 17.0.2. In SDK17.0.2, the memory setting method has changed, so using the SDK17.0.0 example results in a compilation error. The nRF52810 and nRF52805 are products of the same flash and RAM size. You need to copy the nRF52810 example (pca10040e folder) from SDK17.0.2 to create the pca10040e_nRF52805 folder. Applying the steps described in the blog will compile without any compile errors.

Thank you but I just wanted to point out which SDK version I was using.

I've followed the guide steps multiple times to convert the pca10040e projects and everything works fine.

Since I'm starting a new project (for a product) I just wanted to understand if the "vanilla" sdk_config.h of nRF52810 could be used for nRF52805 since they are equivalent from the RAM and FLASH size but differs in some peripherals.

As far as I understand there is no problem, but my concer is that I don't want to run into some issues because I'm using an improper configuration file.
