Please try it (available > from CVS at sourceforge) and tell me if you encounter any problem. I try it with Sony VAIO Laptop (CXD3222,OHCI,1394.a). When I connect VAIO, repeater and PC (TSB12LV23,OHCI), PC's node count is three, but VAIO's node count is still zero. I found VAIO's busReset Interrupt has assert correctly, but selfIDComplete Interrupt has never asserted. I wrote a few code to dump Port Status Register of PHY chip, it seems to be working normal. I'm confused. I think I need to look over 1394 OHCI specification. -- Hiromasa Yoshimoto / yos...@li... |
