I am currently working with a Versatile Express Coretile (2xA15, 3xA7) together with ARM DS-5 and the debugger. There is some example startup code for a A15MPCore in an example project (bare-metal). I was wondering if there is also an example project for this big.LITTLE coretile along with some strartup code? Some code for an A7MPCore would be great as well.
You can download UEFI source code following the instruction here
