MUP6050加载DMP固件失败
unsigned char mpu_dmp_init(void)
{
u8 res=0;
IIC_InitPort();
if(mpu_init()==0) //初始化MPU6050
{
res=mpu_set_sensors(INV_XYZ_GYRO|INV_XYZ_ACCEL);//设置所需要的传感器
if(res)return 1;
res=mpu_configure_fifo(INV_XYZ_GYRO|INV_XYZ_ACCEL);//设置FIFO
if(res)return 2;
res=mpu_set_sample_rate(DEFAULT_MPU_HZ); //设置采样率
if(res)return 3;
res=dmp_load_motion_driver_firmware(); //加载dmp固件
if(res)return 4;
res=dmp_set_orientation(inv_orientation_matrix_to_scalar(gyro_orientation));//设置陀螺仪方向
if(res)return 5;
res=dmp_enable_feature(DMP_FEATURE_6X_LP_QUAT|DMP_FEATURE_TAP| //设置dmp功能
DMP_FEATURE_ANDROID_ORIENT|DMP_FEATURE_SEND_RAW_ACCEL|DMP_FEATURE_SEND_CAL_GYRO|
DMP_FEATURE_GYRO_CAL);
if(res)return 6;
res=dmp_set_fifo_rate(DEFAULT_MPU_HZ); //设置DMP输出速率(最大不超过200Hz)
if(res)return 7;
res=run_self_test(); //自检
if(res)return 8;
res=mpu_set_dmp_state(1); //使能DMP
if(res)return 9;
}else return 10;
return 0;
}
当程序跑到res=dmp_load_motion_driver_firmware();时就出错了，加载固件失败，
for (ii = 0; ii < length; ii += this_write) {
this_write = min(LOAD_CHUNK, length - ii);
if (mpu_write_mem(ii, this_write, (unsigned char*)&firmware[ii]))
return -1;
if (mpu_read_mem(ii, this_write, cur))
return -1;
if (memcmp(firmware+ii, cur, this_write))
{
printf("ii = 0x%x\n",ii);
return -2;
}
}
串口助手打印如下图，每次上电或复位时都这样。希望大神帮忙解决一下。
