I have Qualcomm 820 dev board (APQ8096) with debian linux on top of it. I downloaded SNPE SDK and compiled sample NativeCPP code, but when I try to run the sample I get 

"FATAL        0 tffff88744700 /home/host/build/aarch64-linux-gcc4.9/SecondParty/symphony/src/symphony/src/lib/ runtime_init() This version of Symphony is targeted to Snapdragon(TM) platforms                                         

tffff88744700 /home/host/build/aarch64-linux-gcc4.9/SecondParty/symphony/src/symphony/src/lib/ - Terminating with exit(1)"
Even though I run on snapdragon platform, symphony is not detecting that I m on Snapdragon platform. How do I make this happen? Anybody have faced this issue before? How do I resolve this issue?
This is /bin/bash file info:

So I had to edit cpuinfo.c in the kernel code, and had to add this line

seq_printf(m, “Hardware\t: Qualcomm Technologies, Inc APQ8096\n”);

after this line

seq_printf(m, “CPU revision\t: %d\n\n”, MIDR_REVISION(midr));

and then re-flashed the board and now the binary started working.

I do had the same issue. But after fixing this issue I could run the sample application on CPU but not on DSP/GPU. It is saying that the "The selected runtime is not available on this platform." I have also copied the necessary libraries priovided with the SNPE SDK 1.22 to the file system and the required env's are set. I am running debian on Dragonboard 820C development kit. Please suggest the required runtime that I am missing....
