Centaurus USB_PLL Init is in Progress, Please wait

Other Parts Discussed in Thread: ALP

Respected Sir/Madam,

I am using Centaurus board(TMDXEVM8148 ALP). WHen i try to connect to the Cortex A8 processor, after loading GEL files, it stops at msg on consol:

Centaurus USB_PLL Init is in Progress, Please wait............

or some times it stops at msg:

PRCM for EMIF0, EMIF1 and DMM are in Progress, Please wait...........

and then i got this error:

CortexA8: The GEL callback "OnTargetConnect()" is no longer running atomically

is it GEL files problem or something wrong ? Please help me.

I am using CCS v 4.2.2.00033 and i am using spectrum digital's XDS 510 USB JTAG. i am attaching my gel files also:
