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. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
