Porting onto an iMX6 as an extension of iMX53?

[aditkous]

Hello all,

I'm working on a system that has already been ported for iMX53. (a) Is it logically(and technically) right to proceed in finding all i.MX53 related files and include directories and create an i.MX6 version of the same, and expect it to work?

Obviously the architectures and registers are different. (Cortex a8 vs a9 and other minor differences). Say, for the build on iMX6, the necessary rules are added in the makefiles, the include files under imx53 are tweaked to suit imx6. (b) The build system should still work, right?

(c) How different are iMX53 and iMX6 from each other (from the point of view of porting)?

Thanks and regards

Aditya

Hi, Aditya

     I think the biggest difference between i.MX6 and i.MX53 is the SMP related files porting. As for i.MX6, it is am SMP( high to 4 cores available), and i.MX53 is a single core SOC, so it didn't need to support any SMP related low level interface porting.
