Hi all, We are testing EHCI driver for ARC-OTG based controller core on a ARM 926 board. The platform glue has been written. The driver is compiled to the kernel . When the kernel boots up , the driver is loaded.
We have enabled USB_DEBUG and then going through the prints, its is observed that the root hub has been identified and given the address 1. Since the board has an OTG port, capable of providing 8mA, we connected a SONY DSC camera which is OTG Complaint device. But when we plug a High Speed device , the IRQ function is not even invoked, the STS register and PCD bit in PORTSCx is not showing any change. Those who have worked with ARC USB HS-OTG controllers, have u come across these problems, if yes, please help us. I am attaching the log of trace i did.
