nRF51422 Won`t Debug with IAR Tools

[WestCoastDaz]

I am trying to bring up a simple program on the IAR tool chain 7.40.1 using an I-Jet debugger using the nRFDK. I have this simple programming running under the Keil code limited version using the built in Segger debugger.

It compiles correctly and I can download it to the target but it won`t run past the second statement in main it just keeps running to this point if you free run with it as a breakpoint. If I free run I end up in the __exit function.

I am using SDK8.0.0 as the basis of my startup code and I have --drv_vector_table_base=0x0 in the Debugger Extra Options.

I attached my main.c file as a reference.

Thoughts as to why I can`t run?

Also, can I not single step with the nRF51422 and the I-Jet

main.c

Thanks, Darren

Debugging works with the builtin Segger debugger on the nRFDK 10028 board but not with I-Jet. I am going to create a new question about this.
