Hi,
We are looking in a replacement solution for our obsolete
pentium-Celeron calculator.
For many reasons, we would like to switch to the ARM architecture.
The aimed CPU is the iMX6 Quadcore.
Freescale provides a patched 2.6.35 and 2.6.38 kernel that do not have
all the peripherals (the CAN seems to be missing)
and Emtrion, a CPU module manufacturer, say they provide the additional
patches to have the complete BSP.
It is likely a 2.6.35 only, though.
Xenomai for mx6q does not exist for linux 2.6.35. It only exists for
freescale branch for 2.6.38, or 3.0, as a separate set of patches to
apply before and after the Adeos patches for the vanilla kernel. For
further details, see ksrc/arch/arm/patches/README in xenomai 2.6 sources.
Thanks, yes, as I said, I am aware that the very first work for me will
be to get
the non-xenomai 2.6.38 kernel fully working
Furthermore, we have some stability issues with Xenomai for mx6q with
3.0, the issues looking a lot like an issue with cache. We would ned to
recheck 2.6.38 to see if it had the same issues, but I would bet it does.
Actually my concern was to know if there were currently developments
on that CPU. The fact that they are remaining bugs is not a concern,
as long as they would be likely be corrected in the coming months.
Do these bugs also exist on the mx6 single core ?
