Debugging issue in IAR . Not hitting main()

Actually, I don't find that IAR is so common - certainly not here.

If you have the cash to burn, I'd have thought that Keil was a better bet.

But the IDE is just a tool - my point about learning embedded development stands.

Thank you so much for the reply. The problem got solved using this method. I used nrf connect to erase and install the softdevice and run the program in IAR as u said. Now its perfectly working as i need . :)

Agreed; I haven't tried Monitor Mode in IAR, that's a good suggestion. Maybe if I get time .. I have the shiny new v8.4.0 but haven't tried it yet, will be interesting to see if it's any better.

Currently am working in a startup and doing self training. Since IAR is common in industrial use i was directed to learn this.

To be honest, I don't think nRF52 - or any other BLE SoC - is a great place for a beginner to start.

As you can see from the other replies, the BLE part requires some experience.

Do you have a particular reason for choosing IAR?

That is inherent in the way the SoftDevice works; it is the same in SES, Keil, IAR,or any other IDE

I think the only way around it is to use the Monitor Mode Debugging:

It should work in IAR, but I don't think that's covered in an Nordic materials?.

I can't provide support (I'm not Nordic) but I think I can get you started. Using IAR with a SoftDevice has always proved problematic for us. One way to get a debugging session running correctly in IAR is to first "erase all" flash and then load the Softdevice using either nRFGo Studio or nRFConnect. Then hit the Download and Debug button on IAR and the project will allow you to run, single-step and hit breakpoints. Note that debugging can crash after a breakpoint and then the whole sequence of Erase-Program SoftDevice-IAR Debug has to be repeated.

SES works fine when the SoftDevice is specified as an additional load file. Specifying SoftDevice as an additional load file in IAR doesn't work for us (all versions of IAR, not tried v8.4.0 yet). We pay a lot for IAR; SES is free. IAR do not support Nordic parts correctly, in my view, and no longer supply any Nordic examples.

A good start may be:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf51_getting_started.html?cp=5_1_1

In general I recommend to check out SEGGER Embedded Studio for development, there is tutorial here:
