Hi,
I was trying to compile zeus branch for MPSoC and we are using
multiconfig to also compile PMU firmware.
Error I got was:
--
ERROR: OE-core's config sanity checker detected a potential
misconfiguration.
Either fix the cause of this error or at your own risk disable the
checker (see sanity.conf).
Following is the list of potential problems / advisories:
Toolchain tunings invalid:
Tuning 'microblaze' has the following errors:
Feature 'v11.0' is not defined.
--
And when looking at poky/zeus:
meta/conf/machine/include/microblaze/feature-microblaze-versions.inc
# MicroBlaze versions
TUNEVALID[v8.00] = "MicroBlaze version 8.00"
TUNEVALID[v8.10] = "MicroBlaze version 8.10"
TUNEVALID[v8.20] = "MicroBlaze version 8.20"
TUNEVALID[v8.30] = "MicroBlaze version 8.30"
TUNEVALID[v8.40] = "MicroBlaze version 8.40"
...
TUNEVALID[v10.0] = "MicroBlaze version 10.0"
Kinda indicates that there is no yet v11.0 defined for zeus. In Poky
master it is already there.
Now I started wondering why this is a problem.
There was commit to upgrade PMU for newer microblaze (10.0->11.0):
http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/commit/?h=zeus&id=de77bf7a8a9b1600f449ba42fa0da211c712fef0
If I revert that it seems to continue compiling nicely.
However I believe this is not correct thing to do to change the
microblaze version. In ZynqMPSoC the PMU block is hard IP and you cannot
just upgrade that to newer microblaze version. I tried to find details
of what microblaze version it is but it is kinda hidden well.
If we trust Xilinx's QEMU device tree settings a bit then it might be
8.40 and that should then be set for PMU so that proper microblaze tunes
and such are in use.
