Build examples (nRF52840 BLE) are all Broken. Need Help ASAP!

paley

Ok - 

I've been through this a few times and read the forums, but the current build system is broken.  I'm trying to compile (not even load the board at this point) the ble_hts example from the sdk 16.0 with no luck.  I've had this working in the past - but needed to add some additional functionally to our device.  Simple I though, just fix the code and recompile.  The build system wanted to update (which was my mistake) and now nothing works.  I've reloaded from scratch both the keil IDE and also the SDK and family packs... but keep getting compatibility issues.  Currently the compiler is saying it needs startup:8.27.0 and that the component is not available for target nrf52840_xxaa  which is odd, since this should basically just work (as it's from the nordic examples). 

I also get into the loop of different versions of family packs and sdk.  and also the nice problem with the missing "{" and also the FIRST/LAST issue.

what I need is the correct list of 'things' or 'steps' to load and compile (and hopefully run) one of the BLE examples from a fresh build of the environment (the current documentation is NOT correct and bounces all over the place - it's hard to follow).  make it simple.  just need a list of todo's and links to get the sw to compile and run fro the nrf52840 (prefer the BLE HTS, but not picky)

    ok - tried that.  still not working.  Some specifics.  If tried using the ble_app_template in the ble_peripheral directory.  I'm trying with both the 16.0.0 and 15.0.0 sdk.  16.0.0 is using the 8.27.0 family pack while the 15.0.0 is using the 8.16.0  Both are still not happy with the nrf_erratas.h file (cannot fine, and does not exist in the components or modules areas either).  I'm using the latest Keil ide (just fully reloaded) on a windows 10 system (which is working otherwise for Infineon arm processor correctly).  

    What's next to try?

    Can you see what .c or .h file that includes nrf_erratas.h?

    yea.  it's the template example, the file is system_nrf52.c  line 29

    I have had a similar problem with Keil5 and more recent versions of the device family pack. In my case it turned out to be caused by having an "outdated" version of the 'compiler_abstraction.h' header that didn't define the __UNUSED keyword used by the new errata headers.

    So maybe you have run into the same problem? You can add the __UNUSED definition to the compiler abstraction file included from the nRF5 SDK (headers with key symbol are from "Keil packs") and see it resolves the build error.

    I'm using the latest MDK version:

    ok ... gave that a try.  had a lot of trouble selecting the "manage Run-Time Environment -> Device -> startup to select version 8.32.1  had to do a rain dance to deselect startup and select startupconfig - compile - fail, go back to the section and then I could select that version of the tools.  Ok- so that problem went away, now I'm getting  in file nrf51_erratas.h(40): error: #130: expected a "{" (why nrf51 as I'm using nrf52?)  very strange - and also the error message I've seen before and not been able to successfully resolve either.  I feel like I'm in a circular buffer just going round and round.  

    Shouldn't this be pretty easy?  what am I missing?
