It's a memory mapped Bus mastering device on the PCI bus. while there's an attempt to generate an interrupt by the device DMA engine I get a HW error interrupt which says something like "Master Cycle abort, master or target abort on the PCI bus ( ie either target aborted the xmission or there wasn't any target for the transaction". Is there any particular reason/solution for this problem? Any pointers would be appreciated gratefully.. __________________________________________________ Do You Yahoo!? Try FREE Yahoo!
