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
