You've probably solved it by now (or not).... but...

You have the FPC on the display side upside-down. The blue stuff needs to go towards the PCB. The contacts are AWAY from the PCB.

What ARM processor architecture are you cross-compiling for? Your B+ has an ARM6, your 3B (not plus) has an ARM8. You WILL get segfaults if you try to run ARM8 code on an ARM6.
