Building micro-ecc with SES, SDK14.1https://devzone.nordicsemi.com/f/nordic-q-a/26890/building-micro-ecc-with-ses-sdk14-1Hi, I&#39;m trying to build the secure_dfu_ble_s132_pca10040_debug project and apparently need to add the mico-ecc library. The SDK instructions for building the library call out &quot; 4.9-2015-q3-update of the GCC compiler toolchain for ARM&quot;.
