Hi there,

 

We are using P2041 as the processor and we are looking for a way to make a burst transaction to PCI. Is there a way to make such transaction other than using DMA?

Thank you,

I believe you ask if the core is able to burst to PCI. The core uses burst transactions to to fill/flush cache lines only. So you would need at least to set PCI memory area as cache-able.
