Hi,all
I'm trying developing a HCD for one USB host.But there are some
problems doing the intialization with the host.
The host chip is philips's isp1362.There are HcRhPortStatus[1:2]
registers in it, providing only one plug_in port in the board.
After the INT enabled,there are continuing interrupts,with RHSC
bit set in the HcInterruptStatus register.
I have checked the values of the HcRhStatus register and
HcRhPortStatus[1:2] registers while entering the ISR.The changes list
below.
HcRhStatus=8000 HcRhPortStatus[1]= 100 HcRhPortStatus[2]=100
HcRhStatus=8000 HcRhPortStatus[1]= 100 HcRhPortStatus[2]=80000
HcRhStatus=8000 HcRhPortStatus[1]= 100 HcRhPortStatus[2]=80100
.........
What's wrong with the usb_PORT2? SOS!
Best regards!Thanks.
