Hi,

   We are using nrf51822 QFAAH00 with SDK 110 v8.1.0 in our project, the application will hangs or not work when control stuck at address 0x6b0 (sometimes at 0x640) programmer in debug mode, when we check the call Stack it list with  NRF_POWER_RAMONx_RAMxON_ONMODE_Msk + 0x6ad, "NRF_POWER_RAMONx_RAMxON_ONMODE_Msk " what this indicates? , CSTACK contents are zero, what is cause for this.

added following screenshot images CSTACK,Registers content after Application hang.

 

Thanks,

arm-none-eabi-addr2line is a command line tool, so no need to use it with IAR. In the build folder from your project, you should find a .elf file, use arm-none-eabi-addr2line "on" that file, like described in my previous answer.

 what is address have to give in command line, we are using SEGGER_RTT_PRINTF to print the log messages, sometimes control struck in SEGGER_RTT_vprintf function.

On for example this page, you can find the documentation for arm-none-eabi-addr2line, it can be useful to read.

Please check the address of the hardfault: PC = SP + 0x18 = 0x20002990
