Example ble_app_hrs fails to compile

Question

Background Info 
 
 nRF5_SDK_17.1.0 
 nRF52840DK 
 SES 7.12a 
 
 EDIT: This was due to user-error, see following post for update. 
 I'm trying to test the ble_peripheral /ble_app_hrs example, but I'm having issues either compiling or running it. 
 At first I was trying the example located at ble_peripheral/ble_app_hrs/pca10056/s140 , but after clearing up the errors regarding __printf_tag_ptr and .text/.rodata flash sizes, I'm stuck on this error. 
 Output/Debug/Obj/ble_app_hrs_pca10056_s140/nrf_crypto_hmac.o: file not recognized: file format not recognized 
 I also tried the example located at ble_peripheral/ble_app_hrs/pca10056/ser_s140_uart , and while that one manages to compile without any errors, I run into an issue where the devkit doesn't complete the initialization sequence and seeming just hangs without throwing any errors. I've tried debugging to see what's going on, and the code execution appears to just stop when this is reached. 
 nrf_sdh_ble.c:130 
 ret_code = sd_ble_cfg_set(BLE_CONN_CFG_GAP, &ble_cfg, *p_ram_start); 
 
 How would I go about resolving the compiler error in the first case for the s140 example? 
 Additionally, why would the ser_s140_uart example hang during the initialization sequence? 
 Thanks

Hi, 
 I see from the output that the build all script run without issues, so that should be good then.

 I think I may not have looked enough in your original post though, just the follow-up where you described micro-ecc. 
 Do you intend to use micro-ecc? Nothing wrong with that, but it is not used in the ble_app_hrs example out of the box, and not needed (we use Oberon instead by default). So if the issue is that you were not able to run an unmodified example out of the box I suggest that you back-track a bit, or check which (accidental?) changes you have done to the example when trying to port it to work with a later SES version. 
 If you downgrade SES, the ble_app_hrs example should build out of the box. If it does not, there is a more fundamental issue. If downgrading SES is not enough, please download and extract a fresh copy of the SDK and try that. And if it still does not work, perhaps you can upload the project here and the full build log so that I can have a look.
