SharcFIN Issues

The following is a list of topics relating to BittWare's SharcFIN PCI-DSP bridge chips. Check back often for updates.

• Why does the mailbox status show 0xF when I write to it from the DSP? Wouldn't it only be 0x1?
• What is the maximum DMA size I can set the SharcFin DMA engine up for?
• I am using the DMA engine in the SharcFin to transfer data from the PC Host memory down to the DSP memory. It will run once, but all the other DMA’s never complete. Why is that?
• How do I set up the interrupts to notify me when the DMA is complete?
• How do I tell what version of SharcFin is on my board?
• Where can I find a datasheet that includes mechanical information for the SharcFIN?
