cc430f5137 resets in runtime mode

Other Parts Discussed in Thread: CC430F5137

Hello,
I work with cc430f5137 for a wireless communication project. I have written my program code c++ and compiler is ti v16.9.3lts.
Program works fine in debug mode but it always resets in normal mode or freerun mode.
Watchdog is off. In addition system reset interrupt service routine (isr) , system nmi isr and user nmi isr not been entered.
I don't use heap and there is no stack overflow stuation. I have tested my all functions one by one and all functions work fine but
when i run program as a whole , it resets. Where can the error be ?

Thanks & regards,

Celal

Hello Celal,

An active debugger changes the system timing, when removed it is possible that the MCU reaches a point in the code too soon. Can you share your initialization code, supply voltage, and intended operating frequency? What has the SYSRSTIV determined the reset to be caused by? Are you evaluating with a TI EVM or using a custom PCB? If the latter then please share the schematic and board layout if possible.

Regards,
Ryan

Thanks for repyl Ryan,
I solved the problem. I use mrfi module of simliciti library for simple rf communication. MRFI doesn't init power management module. mcu resets when radio go into rx active mode in low power mode because PMMHPMRE bit of PMMCTL0 register is not set.
I set PMMHPMRE of PMMCTL0 register before calling MRFI_init(), hereby code works fine
