I have a pi B and pi B+ revision 1.2 The model B has Linux version 3.18.7 the B+ has Linux version 4.14.50. The Model B+ Scratch 2 doesn't work, it appears to start to load and then doesn't. I took the SD card out of the B+ and put it in the B and Scratch 2 works fine. Any idea why it doesn't work on the B+? No jargon, if possible at this stage.
