So, was it Digikey that mixed up the parts or the factory that put the wrong 
IC on the board?

As for the RAM, I guess that it made for the "bring up" process, as described 
in that bare-metal Ingenic work, to be slightly more exciting than it should 
have been. When you're probably only somewhat confident that the code will do 
the trick, I guess it's frustrating to have defective hardware involved as 
well.

Anyway, good luck with the printing and soldering!
