Running QNN with Htp backend on embedded linux

Is there any examples of running QNN SDK qnn-net-run with the Htp backend on embedded linux. All the examples are shown on android.

I am working on SA8295 and the CPU and GPU backends work fine. When I try to use the Htp backend (by following the tutorial for qnn-net-run)

I get the following error: 

unsigned PD or DSPRPC_GET_DSP_INFO not supported by DSP

DspTransport.openSession qnn_open failed, 0xffffffff


The qnn-platform validator also does not find the required backend libraries and fails with:

PF_VALIDATOR: ERROR -2. Error while executing the sum function


I have tried to set the LD_LIBRARY_PATH and ADSP_LIBRARY_PATH to all directories i can think of
