So, I want to unlock the 7th SPU, just cause, and I want to use the SPI bus. How does one go about doing that. Apparently, that's on-the-fly enabling, so it should be much safer, reversible, and I can see if I could enable it permanently without bricking. Anyone know how?
Following this site, I can use a Teensy to read from the SPI bus to see if the SPE is faulty or not. http://www.pjrc.com/teensy/td_libs_SPI.html
And using these, since they match my model (CECHE) http://www.ps3devwiki.com/wiki/Syscon_Hardware#Syscon_Cell_SPI_Bus http://www.ps3devwiki.com/wiki/CXR713120-201GB It tells how where to solder, seeing as I'm just reading, there shouldn't be a worry for bricking.
