Forum Post: RE: [MCSDK Video] How to re-launch PCIE demo without reset and dnld DSP?

Hi Hongmei,

Thanks for your help.
The breakpoint in siuVidMc_Unmap_Shmem() can be hit after updating the new H264HP encoder.

I have a question about the usage of Memory_calloc().
The first argument type of Memory_calloc() is xdc_runtime_IHeap_Handle.
How to get or create the xdc_runtime_IHeap_Handle, when I want to call Memory_calloc() in siuVidMc_Map_Shmem()?

Thank you,
Harvey
