Troubles in connecting to and loading program to OMAPL138

When it connect to OMAPL138’s  ARM9_0 through SEED-XDS560PLUS Emulator in CCSv4.1.2.00027,the following error would occur :

And the main GEL codes are:

OnTargetConnect( )

{

    Clear_Memory_Map();

    Setup_Memory_Map();

    PSC_All_On_Experimenter();

       DEVICE_kickUnlock();

Core_300MHz_DDRPLL_150MHz();

    EMIFA_NAND_PINMUX();

    Wake_DSP();

}

And I used “Core_300MHz_mDDR_132MHz();”, “Core_200MHz_mDDR_126MHz();” or “Core_100MHz_mDDR_102MHz();” instead of  “Core_300MHz_DDRPLL_150MHz();”.It could only be configured successfully with “Core_100MHz_mDDR_102MHz();”.

So I’m confused.I don’t know why such a strange phenomenon happens.And what should I do to solve this problem?

Besides,after connect to OMAPL138’s  ARM9_0,I tried to load program “nand-writer_ccs33.out” into the processor for writing “ubl-nand.bin” and “u-boot.bin” into NANDFLASH ,like this:

However,once I clicked “OK”,the processor would be running immediately and never stop!Please look at following picture:

And if I halted it, I figured out that it’s running 2 codes at 0xFFFD397C and 0xFFED3980 in an infinite loop ,like following:

Could anyone help me to solve these problems?
