DA14681 pro board works well with debugger, but halted when run alone

嗨im_dialog，
谢谢你尊敬地重播。这是init代码：
bool i2c_devices_async_init(void)
{
BOOL RET1，RET2;
static const i2c_config cfg = {
.speed = HW_I2C_SPEED_STANDARD,
.mode = hw_i2c_mode_master，
.addr_mode = HW_I2C_ADDRESSING_7B,
};

hw_i2c_init(HW_I2C1, &cfg);
srand（os_get_tick_count（））;

/*
* Get handle to temperature sensor device.
* This call does not configure I2C controller yet.
* /
// tpdev = ad_i2c_open(TP_MMS427);
imudev = ad_i2c_open（imu_lsm6ds3）;
// magdev = ad_i2c_open(MAG_AK09915);
/*
*创建将由GUI使用的事件等待I2C事务完成。
*此活动将用于从GUI任务访问温度传感器或EEPROM。
* /
init_event（＆i2c_signal）;

// ret1 = tp_device_init();

ret2 = imu_6axes_init（）;
/ * Ret1 = Ret1 && Ret2;

ret2 = mag_device_init（）;
Ret1 = Ret1 && Ret2;

//for test only
mag_set_power_mode(4); //100hz refresh
* /返回（RET2）;
}
And the refresh sensor code, which excute in timer notify :
static void refresh_sensor(void)
{
int32_t imudata[6];
int16_t magdata [3];
uint8_t k1status, tpirqstatus;
uint8_t xy[2];

// pm_stay_alive（）;
k1status = (uint8_t)hw_gpio_get_pin_status(APP_BUTTON_GPIO_PORT, APP_BUTTON_GPIO_PIN);
tpirqstatus =（uint8_t）hw_gpio_get_pin_status（tp_irq_gpio_port，tp_irq_gpio_pin）;

if（imu_6axes_read_data（imudata））{
printf（“IO：％d |％d acc：％d，％d，％d，”，k1status，tpirqstatus，（int）imudata [0]，（int）imudata [1]，（int）imudata [2]）;

printf("Gyro:%d,%d,%d\r\n", (int)imudata[3], (int)imudata[4], (int)imudata[5]);
}
/* if (tp_drv_read_coordinate(xy)) {
printf（“tp：％u，％u”，xy [0]，xy [1]）;

}
if（mag_device_read（magdata））{
printf("mag:%d,%d,%d\r\n", magdata[0], magdata[1], magdata[2]);

}*/
// pm_resume_sleep（）;

}

函数IMU_6AXES_READ_DATA使用IMU_I2C_READ函数从IMU读取多个寄存器并计算值：

BOOL IMU_I2C_READ（UINT8_T * PBUFFER，UINT8_T DEVICEADDR，UINT8_TREGRARADDR，
uint16_t numbytetoread）
{
bool ret = false;

ad_i2c_device_acquire(imudev);

if（hw_i2c_abort_none！= = i2c_device_read_async（imudev，＆regreadAddr，pbuffer，1，numbytetoread，＆i2c_signal））
goto exit;

ret = true;

出口：
ad_i2c_device_release(imudev);
返回Ret;
}
I2C读取寄存器功能：信号相关的功能与I2C_DEMO.C中的相同。

static HW_I2C_ABORT_SOURCE i2c_device_read_async(i2c_device dev, uint8_t* reg, const uint8_t *buf, uint8_t reglen,
UINT8_T BUFLEN，I2C_EVENT *事件）
{
/*
* Make sure event is not in signal state yet;
* /
reset_event（事件）;

/*
*编写传感器寄存器，使用回调将信号发生同步。
* /
AD_I2C_ASYNC_TRANSACT（DEV，I2C_SND（REG，REGLEN），I2C_RCV（BUF，BUFLEN），
i2c_cb1（signal_event，事件），i2c_end）;
/*
*等待交易完成。
* /
wait_for_event(event);

/*
* Error code if any is stored in event, return it.
* /
返回Event->错误;

}

I need to emphasize that I can successfully init and read the IMU data for dozens of times before the system halt. the printf output like this:

2017/1/11 10：08：05.658 [rx] -
IMU XG_ID: 0x69

Thank you for your replay.
I followed the demo demo_i2c_async.c exactly. the declare of devices were made in a copy of platform_devices.h in config foler like the demo:
I2C_BUS(I2C1)

#ifdef CONFIG_IMU_LSM6DS3
/ *实施例温度传感器FM75 * /
I2C_SLAVE_DEVICE(I2C1, IMU_LSM6DS3, 0x6A, HW_I2C_ADDRESSING_7B, HW_I2C_SPEED_STANDARD);
＃万一
#ifdef config_mag_ak09915.
/ *实施例温度传感器FM75 * /
i2c_slave_device（i2c1，mag_ak09915，0x0c，hw_i2c_addressing_7b，hw_i2c_speed_standard）;
＃万一

but I can't find any initialize like I2C_BUS_INIT(I2C1); in the demo. So I didn't add them in previous code.

我在硬件init和设备打开之间将宏添加宏：
hw_i2c_init(HW_I2C1, &cfg);
srand（os_get_tick_count（））;
i2c_bus_init（i2c1）;

I2C_DEVICE_INIT(IMU_LSM6DS3);
I2C_DEVICE_INIT(MAG_AK09915);
/*
* Get handle to temperature sensor device.
* This call does not configure I2C controller yet.
* /
// tpdev = ad_i2c_open(TP_MMS427);
imudev = ad_i2c_open（imu_lsm6ds3）;
magdev = ad_i2c_open(MAG_AK09915);

但同样的结果。我应该接下来怎么样？谢谢！
