[U-Boot-Users] PCI OHCI / testing-USB branch

[reckless]

Hi 

I am stuck at the position where iam not getting any data on USB bus. I am
using the ISP1562 chip on my PCI and using the OHCI code. I am able to reset
and initialize the controller as i am able to see the reset signal and High
speed chirp signal on the bus but there is no data on the bus. It shows the
invalid packet on with all 0xFF at the first time i connect the mass storage
device and running the usb reset command what could be the problem ? 
How i have to map the PCI memory ? 
I though that it could be the invalid memory access as i am taking the gohci
and hcca structure by just taking it as an array and the controller HcHcca
registers are unable to access that location it 0x7ffa0000 in my case where
my PCI memory is mapped at 0x80000000 

Need some help 
Regards
