Launch app through NFC Tag scanning in custom application!!!

[Urvisha Andani]

Hello,

I am working on nRF52832 SDK 15.3.0 using segger embedded studio in windows 7.

I am trying to merge two application, one is launch application through NFC and other is template code given in SDK .

1)launch application path: ..\..\examples\nfc\record_launch_app\pca10040\blank\ses

2)template path:..\..\examples\ble_peripheral\ble_app_template\pca10040\s132\ses

In this i got error as shown below,

Have you changed anything in the nfc's header files?

I am not changed anything in nfc's header files.

In ble app template code I am not getting any problem but in my application code I am getting error which is mention previously.

In my application code I added,

1)Device information service

2)Battery service

3)Two custom service

4)DFU service

5)SAADC functionality, In this I take ADC value from 2 pin.

6)GPIOTE interrupt routine, In this I take 1 pin as interrupt.

7)NFC launched app functionality.

Please give me solution.

I found this:

https://stackoverflow.com/questions/9753749/arm-compilation-error-vfp-registered-used-by-executable-not-object-file

It looks like a floating point configuration issue.

Is it possible to zip the project folder and send it here?

Thanks for reply.

I have followed the link provided by you, I got solution.

I changed below setting,

Project-> Option-> Common-> Code generation-> ARM FP ABI  Type = Hard
