Hi all. I am currently trying to simulate a part of my work on isis proteus. It consists of pic 18f4620 and mmc card. I am using ccs for programming the pic. I tried the example that came with ccs, that is, the ex_fat.c example, but though there are no errors in initializing, i tried to use the 'format size' of the code but it just stops at 'Formatting size' and doesn't give either 'error' or 'ok'. Please any suggestions would be appreciated. Thank you.
