(Solved) Coretex core number confusion

(1/2) > >>

athouston:
I am looking to understand a future direction for this work and the ARM industry in general but I am confused about the numbering. If my work progresses to it's conclusion I am going to want a few hundred "sticks" so its a bit important that I pick the correct horse.

The current TCL for RAM is listed as ARMv7 but the AllWinner website denotes A10, A10s and A13 as Cortex-A8 and the A31 Quad Core as Cortex-A7.

How do these equate please.

roberts:
ARM Cortex™-A8 processor is based on ARMv7 architecture, i.e., the instruction set is ARMv7. Of course the ARMv7 architecture is independent of a manufacture's use of u-boot and initial boot loaders. That is why we cannot offer a single image to work on all A10 boards.

athouston:
So the Cortex-A7 is what? armv6 or 5 or something..

athouston:
Sorry, should have also asked..

Do we have a strategic direction as to what architecture we are following,; Allwinner or Rockchip (RK3188 quad core) or Freescale I.MX6. or whatever. Allwinner and Rockchip seem to be dominant in the market but Freescale seems pretty responsive to Linux support.

xyz-worx:
Hi athouston,

you are right, that freescale forces its iMX6 chips and has a quite pretty support for them. Additionally
there is 'real silicon' available for all variants: single core, dual core light, dual core and quad core. I
mention this, because it was not always fact in the past - freescale was a master of announcing, but
not of providing silicon (e. g. the 'Kinetis' line of CPUs).

I think selecting a specific CPU or board depends on your needs also. If you want systems, that have to be available
for more than let's say two or three years, then Allwinners/Rockchips might be o. K. If your need is to have them
significantly available longer, then the freescale chips are more interesting. The iMX6 CPUs are part of freescale's
'Longevity' program, that means they will be available for ten maybe 15 years.

Did you take a look at the 'Wandboard' which is a low cost iMX6-board? You can get it with single core,
dual core light or quad core CPUs. There have a forum and IIRC questions about TC support have been asked.

best regards xyz-worx
