HELLO,
my name is mhemara fay. i have a q for you.
Anyone has successfully extracted a preprogrammed 8051 chip with fuse locked? I want to retrieve the binary image from a programmed 8051 micro any ideas? Thanx
Are you asking for help with copyright violations?
Your question do represent a law violation in a large number of countries around the world!
Ever thought about why chip wendors have implemented the protection, and why developers have chosen to ship their product protected?
oh my god, I misunderstood what "fuse lock" means! I thought he actually has access to the source...!!! mhemara, you potential criminal! now that is even worse than a spammer (see my last post; yuk), and possibly worse that a nigerian bank fraudster :) !
this is mhemara fay agin and thank you for the answres you give.
i am not a criminal! i need toi get code from a chip i programmed. it is my code but i lost the source!
i do not think it is illegal to get my own code.
How did you manage to "lose" the source?
How much source have you "lost"? Was it 'C' or assembler?
Even if you do manage to read the device, remember that it will just be "raw" binary - not full source. So you're still going to have plenty of work to do to get back to any proper source code...
How long would it take to re-write from scratch? That may well be easier/cheaper than trying to "extract" the binary, disassemble it, and turn it back into useful source...
