Power Optimization in nRF52805

[[email protected]]

Hi All,

My application uses as provided below,

MCU  : nRF52805
SDK   : nRF5 SDK 17.1.0
SoftDevice :S112 v7.2.0 
IDE    : Segger Embedded Studio.

and GPIO(BSP),Advertising Modules, Timers, Queue Modules, Random number Generator, libUARTE, Power Management and some common Library. Till now, I commented "nrf_pwr_mgmt_run();" function in idle_state_handle() function, so my code running fine as expected. 

But, Now i need to implement power management, so i unblocked the nrf_pwr_mgmt_run(); in idle_state_handle() function, after some time nrf52805 gets stucked at "p_libuarte->ctrl_blk->evt_handler(p_libuarte->ctrl_blk->context, &evt);"  or at void libuarte_0_handler() as shown in attached pic. Please suggest where I'm doing wrong.

Hi,

It looks like the application stopped at address 0xA60, which is the hardfault handler in the MBR. You can include the HardFault handling library in your project, to get more details about where the HardFault occurs. This library will output the information on the logger.

Also, make sure you build the application in Debug configuration, and check if there are any errors reported on the logger.

Best regards,
Jørgen
