    Hello,

    I'm currently experiencing a hang when loading my Linux EHCI USB Host module, possibly related to the status of the DPLL5 enable code. In researching this, I've found the following in the boot log:

    Disabling unused clock "sad2d_ick"
    Disabling unused clock "modem_fck"
    Disabling unused clock "clkout2_src_ck"
    Disabling unused clock "dpll5_ck"
    clock: dpll5_ck failed transition to 'locked'

    It seems this message may be related to the EHCI problem, does anyone have information on this issue? I've noticed that the 2.6.28 kernel in Logic's binary BSP, as well as the kernel we've built issue this error. I've verified the offsets and macros in cm-regbits-34xx.h against TI's documentation. Now I'm working on comparing the initialization sequence in the kernel, and in U-Boot, to that of WinCE. Any help would be greatly appreciated,

    Thanks,
    Bill
