nRF5_SDK problem with ble_app_blinky_c and nrf52840

[OisinOC]

Hi,

I'm having difficulty getting the ble_app_blinky_c example in nRF5_SDK_15.0.0_a53641a to compile for the the nRF52840 (pca10056). I'm getting the following errors

The nRF 52832 (pca10040) compiles without issue. Can anyone suggest where I'm going wrong?

Thanks

Hi,

Is it possible that your Makefile may have been modified? I tried to build this example for the the PCA10056 board and did not get any build errors. Could you try the same with a new copy of SDK 15.0.0 just to make sure?

Thanks for the advice, I downloaded SDK 15.0.0 and 15.1.0. The examples built without issue in both. I must have modified something that affected it, I put the two makefiles into one of those comparison websites and they were identical. Anyway I deleted the original sdk, replaced it and I'm now up and running.
