Subject: USB failure on mpc8347 based board
Date: Tue, 20 Nov 2007 13:26:11 -0700 [thread overview]
Message-ID: <fa686aa40711201226o74b526fchebb547a8d08886fa@mail.gmail.com> (raw)
I'm seeing the following error on an MPC8347 based board. The
physical board is wired up with the fsl-usb2-dr controller setup as a
USB device using port0 and fsl-usb2-mph as a USB host using port1.
The EHCI driver fails with the following error when initializing the
fsl-usb2-mph controller:
In particular I'm wondering if anyone knows the cause of "HC died; cleaning up".
The board has a hard wired USB hub connected to port1, and the host
controller seems to be dying while probing that device.
Cheers,
g.
