Assuming we're talking about an identical drive. data-medics sent me a donor to solve the pin-out, it's a regular 8bit controller, I solved the pinout but technically in the deal we worked out they "own" the pinout as they wanted to do the work on the clients drive themselves so I can't really share it but if you want to work out something with them feel free. :-)


I don't mind you sharing it on a limited basis. I was only asking that I get the pinout provided to me because I couldn't send the client drive out and wanted to have it for future reference.

Unfortunately in my case, the NAND seemed to be completely dead. Never got the tiniest response at all.

Just something for you here while reading NAND chip,,, the voltage... probably you tried it already... from our experience i found for example some BGA132 requires some customized voltage setting while reading to get ID and have proper reading...
:idea:

Sir ,
I really love PC3K and Its voltage settings for such unique chips ,i have pc3k and vnr yet .

I had a similar case with a different controller where i needed to solve the pinout coz i found no datasheet for it. After reading the NAND i had to face other issues (can't recall if it was lack of xor or more probably ECC).
But i can't think of a way of solving 16bit pinout without a working device, that's what i asked.

I think I saw a discussion on FE forum where Sergey discussed how to find those bits. IIRC it relied on knowing the actual connections but order was not right. From memory it also relied on dumping and looking at the output dump at a certain offset where a known string was. Sandisk I think.
