YES! I FINALLY GOT IT WORKING! I found a program online that basically does the same thing that I am trying to do, and also has read/write to binary file functionality. After using its unprotect function the first time, with no success, I checked the code and found that the addresses for the unprotect command needed to be changed. I changed the address, ran the unprotect again, and finally got it to work. I had attempted to run the unprotect command in my program yesterday, but it seems that I must have neglected some element of the SDP commands, and it didn't work. Another note: The command you provided, oPossum, seems to be the protect enable, not the disable, for the chip. That didn't cause any problems, just wanted to note for anyone reading this thread in the future :) Thanks for your help! |

Funny that the datasheet says the chips are supplied out of the factory with write protect disabled. |
