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

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.

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.

R1 is pointing at the register POWER --> SYSTEM_OFF.

Does your application call sd_system_off() in an interrupt context with high priority?

Thanks!

Could you use arm-none-eabi-addr2line.exe to find the line in the application code that results in the hardfault?

It should be used the following way:

arm-none-eabi-addr2line -e yourapplication.elf address

arm-none-eabi-addr2line -e yourapplication.axf address

Hi,

We Change SDK 110 v8.1.0 to SDK v10.0.0 with softdevice 8.0.0, here also facing same issue application hangs in call stack NRF_POWER_RAMONx_RAMxON_ONMODE_Msk + 0x6ad, and control stuck in lower address 0x6b4,

even i try to set Optimization level to none but result same.

This is happening when no central Device connected to nrf51 module.

PSP:0xFFFFFFFC

Thanks,

First, which optimization level do you use for the code? For proper debugging using the callstack, the optimization level has to be set to '0'.

Looking at the register values:

IPSR Exception number = 0x03 : The interrupt is a hardfault

LR = 0xFFFFFFF1 --> the hardfault comes from an interrupt

PC = SP + 0x18 = 0x20002990 : address of the instruction that hardfaults. That instruction can be found in the .map file generated by the project. Which instruction is causing the hardfault?

PSP: What is its value?
