When I want to implement my edge impulse model to my nrf5sdk code using vs code I found this errors,

I contacted the Nordic dev zone and they advice me to contact your forum They said
" > /…/…/edge_impulse/edge-impulse-sdk/tensorflow/lite/micro/kernels/fully_connected.cpp:1310: undefined reference to `TfLiteTypeGetName’
The output clearly states undefined reference(s) from the Edge Impulse SDK. As this is not a part of the nRF5 SDK you will need to contact Edge Impulse forum for support."
Can you give an advice about how to solve this issue?
Hi @Ghazi ,
Sorry for the late response. Your error suggests that you didn’t add some files to the compilation process. The missing function TfLiteTypeGetName is defined here:
