Re: how to get the DRAM address for DPU output

DPUGetOutputTensorAddress() gives me something like "0x7f79329c00", which is beyond the ddr memory range 0 - 0x8000 0000. This address is possibly the virtual address. I'm wondering how to get the physical address on DRAM.

Re: how to get the DRAM address for DPU output

Just a follow up. I found in xilinx_ai_sdk, the outputTensor class contains phy_addr field where I can extract the physical address. But is there a way to get the physical address using dnndk?
