Hi All,
Our target is QORIQ P2040 based
Uboot is based on 2013.01
Our custom board has a compact flash connected to USB via cypress USB to IDE
bridge. When I run the usb start every other attempt I get EHCI timeout.
Any idea what may be the cause for this ??
Below are the dumps. Please let me know if you need more info
