Continuous, infinite warm reset attempts in Chipidea HDRC on multiple connect-disconects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am using Chipidea HDRC on imx6sl platform. On connecting USB stick
(sometimes) and Android/ Apple phone (frequent) to ci-hdrc multiple
time it is seen that hub (ehci_hub_control())  reports continuous
USB_PORT_FEAT_C_RESET  (infinitely) before a disconnect-connect caused
USB_PORT_FEAT_C_OVER_CURRENT.

I have two queries:
1. Can we avoid the continuous warm reset ( USB_PORT_FEAT_C_RESET )
i.e. can we force hub to initialize again and enumerate the device
again?
2. Do we need to initialize both controller and hub i.e. we
initialized controller (calling ehci_setup() and ehci_run())  but the
hub continued the resets until the overcurrent bit was set.

Thanks&Regards
