Just picked up a Medusa 2, and I must say I'm a bit disappointed with the limited testing I've done. The first ~10 boards (parts boards, albeit, but all with SPI present and no damage or missing components or anything to that area of the board) or so that I tried to simply read the serial/BIOS info from, didn't work. The tool kept saying "no chip found", etc. So, I hooked it up to a known-working board and same thing--no chip found. Tried 5 other known-good boards, same thing. Bummer. So, I connected power to the known-working board, and the tool began working. This of course won't work with many parts boards that have many components missing that are needed to power (or at least reach 3v3_sus). Am I going to have to provide 3.3v to every chip that I want to read?! I was not expecting to need to connect power to every single board that I pull BIOS info from. If I'm going to go that far, the tool doesn't save as much time as I was hoping it would.
Anyone have this issue? In the videos shown to show off the tool, he did not connect power to the test-board, and in fact showed it working on a POS 4924 parts board from China with everything pulled, basically. He did mention having a wire connected to 3v3_sus "just in case it needs power", but he didn't ever use it. I simply cannot believe that I'll need to power the 3v3_sus line for every single board I want to pull a serial from...seems like a huge hassle, and if I'm going to go that far, I might as well just pull the BIOS chip. Was really sold on this thing being able to quickly connect and pull BIOS info without any additional effort.
Anyone have any ideas or experience with this?
