can dsp use external device in dm8168

cheney liu

I donn't know the affiliation in cortex-a8 and c647x. The cortex-a8 is the host core,and only the cortex-a8 can use the external device eg pcie.When i want to get the data from pcie in c647x,can i give up cortex-a8 and how to setup?

Best Regard's!

Hello,

The masters on this device that can access PCIe registers directly are the Cortex-A8 and EDMA.

Hi,

Thank you for your help.

So the cortex-a8 is a master device,the c647x can not access any external devices directly.If i want to manage data that get from pcie device and send to eth,i must do it follow this pcie->cortex-a8->c647x->cortex-a8->eth.

I'm so sorry for my poor english!

Regards,

Cheneyliu
