Subject: [U-Boot] U-Boot 1.3.4 ERROR: CTL:TIMEOUT

Message-ID: <1748B2CB79CD4C4C98B0B27EA13787CD1FE06D27@SGSIMBX007.nsn-intra.net> (raw)

I'm getting the following error message, which leads to a continuous reset loop in my CPU (MPC8548).
U-Boot version is 1.3.4 and latest OHCI patches are available.

Any advice how to recover from this issue? Neither "usb start" nor "usb reset" seems to help.
Only powering off/on the HW can help the situation.

I need to prevent reset loops by being able to recover from this potential issue in runtime.
