nRF52 SDK compiling fail with Keil

[Mich]

Hello,

I was trying to compile a BLE proximity project with Keil nRF52 SDK, but got error such as struct "" has no field. I can command out all these error and compile it. BLE seems to work fine. But I feel just not right to do it in this way. Does any one have the same experience? Any better solutions?

I just compiled the unmodified ble_app_proximity. No errors. You haven't modified anything? Could you include a screenshot in your question?

Hi Petter,

I didn't modify anything. I just attached the the screen shot on my original post. Thanks.

I have the exact same problem here. I see the same happening for either the heart rate or the ble uart example. I used to do nrf51 development on the same machine but I have updated to the latest packs and SDK. The basic blinky sample works just fine but that doesn't use the same startup file. Note: I tested both the SDK 0.9.0 and 0.9.2 and I see the same behavior.

I believe you get these errors because you are using an Device Family Pack that is incompatible with the SDK.

The Device Family Pack that can be downloaded together with the SDK is 8.0.3. As you can see here. Install it in the Pack Installer by clicking File->Import...

It can be a bit troublesome to downgrade this from 8.0.5 or 8.1.0 which I guess you are using, but this should work:

1. Uninstall all 8.x.x device family packs (except 8.0.3 if you have it). Then it should look like this in the pack installer:

The Select Software Packs should look like this:

And the Run-Time Environment should look like this:

You also need to delete the _build and the RTE folders in the project folder. If you compile now, you shouldn't get any errors.

Thanks Petter. I deleted pack 8.1.0, but I can't delete RTE folder because the compiler will complain that there is no startup.s code. Therefore, compiling still fails. However, I opened the SDK link and found that there is a new version 9.0.2. I use this one and am able to compile successfully. developer.nordicsemi.com/.../
