    Hi, thanks for the screenshot. You mentioned above that GUI demos with EVE cores fail, what about if you try to run them with only DSP (-e)? do they work?. Also, could you run below command?

    # cat /proc/cmem

    Ideally we would see 0x20000000, in my board AM5749 I see 0x18000000 (384MB) which is more than OK as I have 2 DSP+ 2EVEs 

    Could you run classification with 1 EVE as a test? example below

    ./tidl_classification -g 2 -d 1 -e 1 -l ./imagenet.txt -s ./classlist.txt -i ./clips/test10.mp4 -c ./stream_config_j11_v2.txt

    I found some environmental values we used for a Mobilenet demo.. so depending on the demo and NN this could change, but just to give you and idea..

    export TIDL_PARAM_HEAP_SIZE_DSP=15000000
    export TIDL_NETWORK_HEAP_SIZE_DSP=5000000
    export TIDL_PARAM_HEAP_SIZE_EVE=15000000
    export TIDL_NETWORK_HEAP_SIZE_EVE=99000000

    Just for your information, TIDL_PARAM_HEAP_SIZE_DSP and TIDL_PARAM_HEAP_SIZE_EVE are the Heap sizes for constant parameters. TIDL_NETWORK_HEAP_SIZE_DSP and TIDL_NETWORK_HEAP_SIZE_EVE are the heap sizes for network scratch memory (activation). 

    If CMEM is 512MB we can give a try to above heap sizes and try 2 DSP + 4 EVEs demos..

    Thank you,

    Paula
