How to fix "Error: Run application fail 21“ on klm630

Dear Kneron,

We got this error message from klm630 96 board when we try to run "host_stream" app with our self trained model replacing the original one "models_630_211.nef", It seems that the error was came from Kneron api which we don't have the source code package, the only infomation we can found is

KP_ERROR_INVALID_MODEL_21 = 21, //kp_struct.h

Now we have no idea about how to fix this, is that means we need to do some changes inside our model or from the host_stream app side? can anyone help on this?

Note :we already successfully run this model on kl720 with only difference of platform setting.
