Keil build failed with undefined symbol nrf52_handle_approtect

[snowuyl]

I use Keil to build nRF5_SDK_16.0.0\examples\dfu\secure_bootloader\pca10040_s132_ble\arm5_no_packs. But it failed to build with  undefined symbol nrf52_handle_approtect. And I can't find nrf52_handle_approtect() function definition in nRF5_SDK_16.0.0 source code.

Hi, 

You can replace <sdk root folder>/modules/nrfx/mdk/ the existing files there with mdk.7z and try again. 

Regards,

Thanks for your suggestion! I will try it on next monday.

Thanks for your support! secure_bootloader can be built successfully after merging mdk.7z. But I encounter another problem. I can't see any debug message from RTT after programming bootloader hex file and I can see debug message if I don't program bootloader hex file.

Hi, 

Please use the secure_bootloader example with _debug version to get debug log.
