DA14681 Pro Board适用于调试器，但单独运行时停止

Hi IM_Dialog,
Thank you vour kindly replay. Here's the init code:
bool i2c_devices_async_init（void）
{
bool ret1, ret2;
static const i2c_config cfg = {
.speed = hw_i2c_speed_standard，
.mode = HW_I2C_MODE_MASTER,
.ddr_mode = hw_i2c_addressing_7b，
};

hw_i2c_init（hw_i2c1，cfg）;
srand(OS_GET_TICK_COUNT());

/*
*获取温度传感器设备的手柄。
*此调用尚未配置I2C控制器。
*/
// tpdev = ad_i2c_open（tp_mms427）;
imudev = ad_i2c_open(IMU_LSM6DS3);
// magdev = ad_i2c_open(MAG_AK09915);
/*
*Create event that will be used by GUI to wait for I2C transactions to finish.
*This event will be used for access temperature sensor or EEPROM from GUI task.
*/
init_event(&i2c_signal);

// ret1 = tp_device_init（）;

ret2 = imu_6axes_init();
/* ret1 = ret1 && ret2;

ret2 = mag_device_init();
ret1 = ret1 && ret2;

//仅进行测试
mag_set_power_mode（4）;// 100Hz刷新
*/ return (ret2);
}
和刷新传感器代码，在计时器中突出的折断通知：
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();

}

the function imu_6axes_read_data use imu_i2c_read function read several registers from IMU and calculate values:

bool imu_i2c_read(uint8_t* pBuffer, uint8_t DeviceAddr, uint8_t RegisterAddr,
uint16_t NumByteToRead)
{
bool ret = false;

ad_i2c_device_acquire（imudev）;

if(HW_I2C_ABORT_NONE != i2c_device_read_async(imudev, &RegisterAddr, pBuffer, 1, NumByteToRead, &i2c_signal))
转到退出;

ret = true;

exit:
ad_i2c_device_release（imudev）;
return ret;
}
the I2C read registers function: the signal related funtions are the same as in i2c_demo.c.

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 *event)
{
/*
*确保事件尚未处于信号状态;
*/
reset_event(event);

/*
*Writing sensor register, use callback that will signal event for synchronization.
*/
ad_i2c_async_transact(dev, I2C_SND(reg, reglen), I2C_RCV(buf, buflen),
I2C_CB1(signal_event, event), I2C_END);
/*
*Wait for transaction to complete.
*/
wait_for_event（事件）;

/*
*错误代码如果在事件中存储，则返回它。
*/
return event->error;

}

我需要强调，在系统停止之前，我可以成功识别并读取数十次的IMU数据。printf输出如下：

谢谢你的重播。
我完全遵循演示演示_i2c_async.c。设备的声明是在platform_devices.h的副本中进行的，如demo，如demo：
I2C_BUS（I2C1）

#ifdef config_imu_lsm6ds3.
/* Example temperature sensor FM75 */
i2c_slave_device（i2c1，imu_lsm6ds3，0x6a，hw_i2c_addressing_7b，hw_i2c_speed_standard）;
#endif
＃如果def CONFIG_MAG_AK09915
/* Example temperature sensor FM75 */
I2C_SLAVE_DEVICE(I2C1, MAG_AK09915, 0x0c, HW_I2C_ADDRESSING_7B, HW_I2C_SPEED_STANDARD);
#endif

但我找不到任何初始化，如i2c_bus_init（i2c1）;在演示中。所以我没有在以前的代码中添加它们。

And I add the macro in init between hardware init and devices open:
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）;
/*
*获取温度传感器设备的手柄。
*此调用尚未配置I2C控制器。
*/
// tpdev = ad_i2c_open（tp_mms427）;
imudev = ad_i2c_open(IMU_LSM6DS3);
magdev = ad_i2c_open（mag_ak09915）;

But get the same result. What should I try next? Thank you!
