Oh that one. Anyone ever have a reliable PCI bus with one of these?
The one system on a board I have worked with in the past had so many
problems with the PCI bus that we have to switch to another board
instead. Too bad since the ARM cpu was much faster and better and
handling network traffic (we switched to a Geode SC1200 based board).
At the time my theory was that the cpu would interrupt DMA transfers
when it wanted access to system memory, which would break the PCI
transfers. But that was just my theory.
Really? I have no idea if it's possible to get a reliable PCI bus or
not with this chip. Right now, we only use it for it's built-in OHCI
USB host controller and UART. You're making me hope I never have to
use it for interfacing a PCI card!
