I'm also very interested in such functionality, so if you make it work, please let me know. :) On Mon, 2003-12-01 at 10:04, Cho, joon-woo wrote:

Hello.

Have anyone use IXP1200's DMA operation? I want to use DMA for transferring data from host computer's memory to IXP1200 evaluation board. Sure, my IXP1200 EB is attached to host computer through PCI slot.

And I write Microengine program like below

1. Make DMA descriptor.

2. point tmp1 to DMA descritptor's address

3. And use pci_dma instruction like below

pci_dma[tmp1, 0, any_queue], ctx_swap

But, after pci_dma instruction, nothing is done more.

Do I mistake? Or do you have similar situation?

Please give me any advice.
