sporadic hardfault on nRF51822 SDK9 S130

[Mikhail]

Sporadic program restart from main. I suppose, it is hardfault exception. How can I catch it?

Check pls my memory settings. ROM: start- 0x1c000 size 0x23000 RAM: start- 0x200028000 size 0x5800

stack and heap I changed to 1024 for each.

and, pls, any idea how to catch this reason of reset to main(). Thanks

If program reset in app_error_handler() due to error then set breakpoint inside that function. If it is hardfault exception then you may find some help here
