Did you try with empty (not windows formatted) MMC? Do you have communication with this CPU? Try firmware update : Operating System Updates for CPU 313C If that does not help ----> Support request. Regards, Marcjan

You can do the update manually take a look: Operating System Updates for CPU 313C you'll need another MMC

If the CPU doesn't work with empty MMC, there is realy a problem. Use the empty card to try to update your firmware, normaly program will not be lost, it's at the other MMC. But since this CPU is already defective somehow, there is no quaranty for anything i write. Regards, Marcjan
