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
