Hello,
any one know why is not useful the SST39SF040 ? i'm using epia-m and it works fine with SST39SF020 but with the other one the computer is dead.
did you build a 512K image or just a 256K image? this is a common mistake.
I think it is safe to build a 256kB image but you have to put it in the UPPER half of the SST39SF040.
This worked for me. See my scriblings here:
