CC2530: Problem with internal 32k RC oscillator

Hi,guys,

 Does anyone have any problem with an internal 32.768 kHz RC oscillator on CC2530?

 I use z-stack with z-home 1.2.0.The bootloader is configured external 32k  crystal oscillator and app program is configured internal 32k RC oscillitor.

There are separately use HAL_BOARD_INIT() to initialize the clock.But  the program not works properly on the hardware that have external 32k crystal

oscilliator.

Why does this happen? Thank you！
