Hi. Im attempting to get the USB function on the TC6393XB (Toshiba multi-io chip) working. This chip is used in their PDAs, including the e740, e750, and e800.
I have register documentation for the chip but it is very sparse, however I can bring up the USB and have OHCI registers in memory which seem to make sense, and respond to plug/unplugging. I cannot see any interrupt activity at all, which I suspect is the major problem. I know little of USB hosts, so Im a bit lost on where to start now. The register set is OHCI. is there a way to provoke interrupts from an OHCI chiip? I need to be able to generate interrupts reliably so that I can work out how to set up the chips interrupt masking / routing. further, the chip has an on-board 32k buffer which the documentation suggests must be used to send data to / from the device (td/eds ?) but it makes little mention of wether the chip can handle DMA or anything else. I suspect it cannot. I have based my driver on the sa1111 driver and it seems able to attach to the chip and produce sane output in /sys TIA. ------------------------------------------------------- This SF.Net email is sponsored by The 2004 JavaOne(SM) Conference Learn from the experts at JavaOne(SM), Sun's Worldwide Java Developer Conference, June 28 - July 1 at the Moscone Center in San Francisco, CA REGISTER AND SAVE! http://java.sun.com/javaone/sf Priority Code NWMGYKND _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
