Hi all,

Currently i facing problem where i cannot get the HPD interrupt.

I checked the hardware signal, when plugged in, the HPD pin is HI, and when plugged out, the HPD pin is LO.

However, kernel does not goes in to irq routine mxc_hdmi_hotplug, and also not going in to hotplug_worker at all.

Any idea why is this happening? i am using kernel BSP 3.0.101.

 

Regards,

ZC
