Issue Enabling MMU on Beagle using JTAG Emulator

Hi All,
I just started using my Beagle with a JTAG Emulato(XDS560), Though I
could able to connect and run my ARM code on the Emulator with MMU in
OFF state.but when tried to run the code with MMU as ON it is
throughing some exceptions.

Please find the details below

The exception I am getting is

Trouble Setting Breakpoint with the Action "Terminate GEL_Go()" at
0x8000ac78:
Error 0x80001828/-1141
Fatal Error during: Break Point, Execution, Timeout, Target,
Processor communication timeout.
It is recommended to RESET EMULATOR. This will disconnect each
target,
perform an emulation reset, and then reconnect each target.
Power cycle the target board before continuing.

FYI, .... Following is the clock setup during reset
OMAP 32K Watchdog Timer is disable
Putting DPLL into bypass before proceeding
Putting CORE DPLL into bypass before proceeding
Locking CORE DPLL
PRCM clock configuration IIA setup has been completed
SystemClock = 19.2 MHz
DPLL_MULT_VALUE = 242
DPLL_DIV_VALUE = 13
CORE_DPLL_CLK = 663.771 MHz
CORE_CLK = 331.8855 MHz
L3_CLK = 165.9427 MHz

and the memory map I am using is

/* SPECIFY THE SYSTEM MEMORY MAP */

MEMORY
{
    DDR : org = 0x80000000 len = 0x04000000
}

/* SPECIFY THE SECTIONS ALLOCATION INTO MEMORY */

SECTIONS
{
    .bss : {} > DDR /* GLOBAL & STATIC
VARS */
    .sysmem : {} > DDR /* DYNAMIC MEMORY ALLOCATION
AREA */
    .stack : {} > DDR /* SOFTWARE SYSTEM
STACK */
.data : {} > DDR
    .text : {} > DDR /*
CODE */
    .cinit : {} > DDR /* INITIALIZATION
TABLES */
    .const : {} > DDR /* CONSTANT
DATA */
    .pinit : {} > DDR /* TEMPLATE INSTANTIATION
TABLES */
}

Did anyone hanged up with similar issue, Can you please help me in
resolving the issue.

Regards,
Gopi
