I have some SNPE code I'm trying to run on the CDSP.  When calling:

```
zdl::SNPE::SNPEFactory::isRuntimeAvailable(
          zdl::DlSystem::Runtime_t::DSP)
```

I get the following errors:

```
DspTransport.createUnsignedPD unable to load unsigned PD
```

Any suggestions?

Thanks!

Hi, I know this is very old topic. Did you manage to find a solution (or reason) yet?
