Forums - SDK 2.0 examples compatibility across different chipsets

Thanks to the Qualcomm/Hexagon_SDK/2.0/tools/scripts/*_walkthrough.sh scripts, it has been relatively easy to test across a number of devices. At our office we have a Snapdragon 800 Dragonboard, 810 MDP phone, Open-Q 820 dev kit, 820 MDP phone, and 820 MDP tablet.

Long story short, here is a grid of our success or failure at running DSP code across the four walkthrough examples:

            calculator      calculator_multi   downscaleBy2      cornerApp

800          pass                    fail                       pass                      fail

810          pass                    pass                    pass                     pass

820          pass                    pass                     fail                        fail

We are using both the Linux and Windows SDKs dated January 18th, 2016. We unfortunately don't have any 805 development boards to test with.

To be specific on the failure signatures, calculator_multi is unable to find libmdsprpc.so while the two dspCV examples (downscaleBy2 and cornerApp) can fail with an error code from dspCV_initQ6(). And in fact even the cases where I've marked calculator_multi as a pass, it fails to run on the mDSP while the aDSP calculation does succeed.

Originally we were hoping to primarily develop on the Snapdragon 820 with Hexagon 680, but the limited success there is what led us to go back and test older devices. It's quite a hindrance if we cannot use dspCV at all on the newest DSP.

Are these results in line with how SDK 2.0 is supposed to work? In that case, are there other dspCV examples or some way to get these working on Snapdragon 820?

We have yet to try the add-on for HVX or the FastCV SDK, but can look into that next if it's necessary.
