What's the correct way to use a custom bsp .scc file located in my custom bsp layer? For purposes of this email let's say it's name is myplatform-preempt-rt.scc. If I specifically add it to the yocto-linux-rt_4.4 SRC_URI it appears to get processed twice by scc according to the meta-series output file. It then tries to apply patches to standard/preempt-rt/base that don't apply. When building on a intel-core2-32 platform, intel-core2-32-preempt-rt.scc only gets processed once and no incorrect patches are applied.
Something could have broken, I never rule out bugs! Morty had some different semantics than the newer branches (which are simplified compared to the auto-resume logic in old releases). That being said, the capability to have a BSP description in the SRC_URI is there, and did work during that release cycle. To have it work, you do need the right format in the BSP .scc file, in particular something with the KMACHINE and KTYPE descriptions will be seen as an entry point, and not trigger the re-application of the inherited patches. Is there any way that I can see the contents of that .scc file ? Otherwise, I can spin up a morty build and mock something up myself. Bruce
If I don't include it in the yocto-linux-rt_4.4 SRC_URI it's never applied at all. I'm wondering if this a new problem with the last big push to morty since I didn't notice this before. I also verified that I can make myplatform-preempt-rt.scc work by doing the following (only shows as processed once in meta-series and no incorrect patches applied): bitbake -c cleanall linux-yocto-rt bitbake -c unpack linux-yocto-rt Manually copy myplatform-preempt-rt.scc and related .scc, .cfg files to the following path: work/myplatform-oe-linux-gnueabi/linux-yocto-rt/4.4.36+gitAUTOINC+b846fc6436_61d7bf47fe-r0/kernel-meta/bsp/myplatform/ bitbake -c compile linux-yocto-rt Regards, George McCollister
