nrf_sdh_freertos_init(scan_start,NULL) & Multilink → HARD FAULT

[Haven]

Hi,  I am using the Nordic nRF52832, with v15.2 of theSDK, and would like to use "nrf_sdh_freertos_init" to implement multilink. I refer to example "ble_app_multilink_central" to code the pair of multilink.

     Everything went well until I turn the slaves off. It shows  <error> hardfault: HARD FAULT at 0x00026EEE  <error> hardfault: R0: 0x68000009  when i turn the last slave off. 

Any help would be appreciated.

Hi Haven, 

The Hardfault address 0x00026EEE is inside the application code. The below line should be able to reveal the instruction that is causing the hardfault. We can take a closer look after understanding what that is.

addr2line -e <src.elf> 0x00026EEE
