PCIe Base address for dsp

Radhakrishna Gotur

Hi,

Where I can find the base address for PCIe pheripheral registers for the TMS320DM814x devices for C674x DSP .

Section 2.12.2 of datasheet (http://www.ti.com/lit/ds/symlink/tms320dm8148.pdf) shows the memory map for the C674x DSP where base address for PCIe pheripheral registers for C674x DSP is missing.

Can any one please help me with this.

Thanks and regards

Radhakrishna

PCIe memory will have to be accessed via a bus master: either Cortex A8 or EDMA controller.

I would suggest using EDMA controller if you need PCIe access from DSP.

To do this DEMMU will have to be programmed as well.
