Dear Qualcomm Team:
 
I'm using SNPE to implement a simple CNN netowrk model in snapdragon 8gen1, I tested model in CPU and GPU, both of them work; but it crashed in DSP. I  used "snpe-platform-validator --runtime dsp" and received the following error message:
 
snpe-platform-validator --runtime dsp
PF_VALIDATOR: DEBUG: Calling PlatformValidator->setRuntime
PF_VALIDATOR: DEBUG: Calling PlatformValidator->RuntimeCheck
PF_VALIDATOR: DEBUG: Setting up QnnBackend
DspTransport.openSession qnn_open failed, 0x00000072
IDspTransport: Unknown rpc status 0x00000072
DspTransport failed,cannot open session, error 0xffffffff
terminating with uncaught exception of type DlSystem::RuntimeException: QnnBackend_initialize failed: 1
Aborted 
 
I used SNPE version 1.63, before we successfully ran my model in snapdragon875 in DSP.
I didn't use UDO and my model is a simple CNN network, I'm wondering why I need QNNbackend in snapdragon 8 gen 1.
How can I run my model in dsp of snapdragon 8 gen 1.
 
BR.

I think the issue is related to path setting. Can you please follow this link (similar problem is described) to set required paths and try again?
