Hey,

I have the new HDK8450. I have tried to run a CNN with snpe 1.52 on  DSP runtime and it falls back to CPU. The same code works with DSP on 8350. is snpe support running in HDK8450 DSP? 

Thanks.Dan

Hi!

I have the same problem (SNPE 1.6.0). When running snpe-platform-validator I am getting this:

taro:/data/local/tmp/snpe_1_6 $ print $LD_LIBRARY_PATH
/data/local/tmp/snpe_1_6
taro:/data/local/tmp/snpe_1_6 $ export ADSP_LIBRARY_PATH="$(pwd)/dsp;/system/lib/rfsa/adsp;/system/vendor/lib/rfsa/adsp;/dsp"                                                                                     
taro:/data/local/tmp/snpe_1_6 $ ./snpe-platform-validator --runtime all                                                                                                                                           
SNPE is not supported on this SoC.

I got exactly same kind of error when trying to '--use_dsp' with snpe_bench.py on 8450 HDK. 

The error message looks like:

2022-03-22 09:25:52,371 - ERROR - snpebm.snpebm_device: ['error_code=500; error_message=Target runtime is not available. error_code=500; error_message=Target runtime is not available. No viable runtimes available.; error_component=Host Runtime; line_no=409; thread_id=518391090432; error_component=Host Runtime; line_no=267; thread_id=531661673720']
2022-03-22 09:25:52,372 - WARNING - snpe_bench: Failed to perform benchmark for DSP_ub_tf8_timing.
 
Maybe the SNPE SDK still cannot fully support convert models which support sm8450. The snpe-dlc-quantize tool in the latest SNPE v1.60 only has knob like '--htp_socs sm8350' instead of 'sm8450'.
