Hi,
I am using a LITE5200 evaluation board, and am not able to enable the
 cache.
The execution hangs in these calls.
void EnableInstCache(void)
{
     __asm(" mfspr   r5,1008");
     __asm(" ori     r5,r5,0x00008800");// # Set the ICE and ICFI bit
     __asm(" andi.   r6,r5,0x0000F7FF");// # clear the ICFI bit for the
 final store
     __asm(" mtspr   1008,r5");
     __asm(" isync");
     __asm(" isync");
     __asm(" isync");
     __asm(" isync");
     __asm(" sync");
    __asm(" mtspr   1008,r6");// # Do the final store
    __asm(" isync");
    __asm(" sync");

}

void EnableDataCache(void)
{
     __asm(" mfspr   r5,1008");
     __asm(" ori     r5,r5,0x00004400");// # Set the ICE and ICFI bit
     __asm(" andi.   r6,r5,0x0000FBFF");// # clear the ICFI bit for the
 final store
     __asm(" mtspr   1008,r5");
     __asm(" isync");
     __asm(" isync");
     __asm(" isync");
     __asm(" isync");
     __asm(" sync");
    __asm(" mtspr   1008,r6");// # Do the final store
    __asm(" isync");
    __asm(" sync");

}
What could be the problem?
Thanks
-San
