Exception "hresult_error" when debugging #54

Closed ranchenhao closed 3 years ago

ranchenhao commented 3 years ago

I have successfully built the sample solution. But got "hresult_error" when debugging it on Hololens.

Exception thrown at 0x00007FFDB5CC39EC (KernelBase.dll) in CalibrationVisualization.exe: WinRT originate error - 0x8000FFFF : 'Catastrophic failure'. Exception thrown at 0x00007FF6833EF284 in CalibrationVisualization.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

The first exception occurred at "winrt\base.h" throw hresult_error(result, take_ownership_from_abi);

The second exception occurred at "Windows.UI.Core.h" template <typename D> WINRT_IMPL_AUTO(void) consume_Windows_UI_Core_ICoreWindow<D>::KeyDown(winrt::event_token const& cookie) const noexcept { WINRT_VERIFY_(0, WINRT_IMPL_SHIM(Windows::UI::Core::ICoreWindow)->remove_KeyDown(impl::bind_in(cookie))); }

I don't know anything about winrt and have no idea how to adress this problem. Would anyone help me with this?

Can you check that Research mode is enabled in the device portal. See the Setup section in https://github.com/microsoft/HoloLens2ForCV/blob/main/Docs/ECCV2020-Tutorial/ECCV2020-ResearchMode-Api.pdf (slides 7 and 8)

Thanks

Thank you! The problem is solved. I allowed sensor access in "Recording mode" instead of "Research mode". However, it seems that before I update the system in Hololens, I cannot find the "Research mode", only "Recording mode".

Anyway, problem solved. Thank you!
