Re: [pci] Burts Reading with a Slave Pci Target



Thanks a lot Sebastian and opencore people,

I've got to read in mode burts from a PCI slave target at 40 MB/s.

Nevertheless, Does anybody know if I can read with more than 8 double words per transference. If the read transference has more than 8 data phases(for example 128) I will be able to run faster.

How can I change the predefined 8 data phases in burts mode per transference?

Thank you very much,

josé lópez, maxjosel@yahoo.es
