| 00:22.10 | tlwoerner | Jin^eLD: sorry, i don't currently have any "projects" with a rockchip board, if it boots i'm happy. a long time ago ARM devices used ATAGS as a way of passing parameters between U-Boot and the kernel; those have been phased out, but there's got to be some valid mechanism |
| 00:22.36 | tlwoerner | i know there's a bunch of config knobs in the kernel to select which ways to expect parameters from a bootloader, maybe more need to be turned on? |

| 14:46.26 | Jin^eLD | tlwoerner: I was hoping that I would not, actually it would be enough for me to be able to pass root=/dev/mmcblk1p${active_root} and then swupdate sets active_root variable in the u-boot env from userspace |
| 14:46.50 | Jin^eLD | then I could sysboot or bootm the chosen partition |
| 14:50.05 | Jin^eLD | I tried only with sysboot so far, there bootargs were ignored although kernel config suggest it should work |
| 14:50.16 | Jin^eLD | so maybe bootargs work only in combination with uboots bootm command |

| 19:43.27 | Jin^eLD | is it possible to have an IMAGE_FSTYPES per recipe? or is IMAGE_FTYPES always global for everything? |
| 19:53.24 | Jin^eLD | if I use wic's rootfs plugin then the result is simply not what I want, but then again I can not use --rawcopy to simply dump the ext4 rootfs into the partition because for rawcopy stuff should have been built earlier by another receipe I guess |
| 19:53.44 | Jin^eLD | at least I was not able to tell wic to dump the ext4 into the wic from within the same recipe |

| 20:14.45 | mnemoc | I'm trying to move the build of a pyro-based distro to a different server. all layers are at the same hash, but write_deploy_manifest fails because it can't find build/tmp-musl/deploy/licenses/systemd-boot/recipeinfo |
| 20:16.07 | mnemoc | it never built systemd before, I tried overriding it with EFI_PROVIDER = "grub-efi" ... and now the same fails but for grub-efi |
| 20:16.17 | mnemoc | any hint on what could I be missing? |
| 20:17.45 | mnemoc | who usually pulls EFI_PROVIDER in? |
| 20:32.56 | tlwoerner | BlastuR: only some of A's files will end up in B's sysroot. e.g. the -dev files would, but binary files wouldn't. so it depends on what ends up in A's packages |
| 20:33.27 | tlwoerner | (or vica versa) |
| 20:38.38 | tlwoerner | mnemoc: my guess is that years of accumulated cruft had simply put the right file(s) in the right place(s) on your old build server. a completely clean build on the old buildserver would probably fail too |

| 22:03.38 | BlastuR | tlwoerner: so, seem to be decided by SYSROOT_DIRS variable in staging.bbclass. Funny, it defaults to ${includedir}, but even if my recipe installs stuff to ${D}${includedir}, and those files are present in the ${WORKDIR}/image directory, they still don't get included in the sysroot :( |

| 22:05.16 | BlastuR | (2019-04) |
| 22:08.07 | BlastuR | i suspect it has something to do with the fact that my recipe where the sysroot isn't populating properly is a kernel recipe (includes linux-yocto.inc), which in turns inherit kernel.bbclass. In that class, there is a lot of funky stuff going on with the PN, FILES,.. essentially rewriting the package name to always be "kernel" and moving all FILES from the original ${PN} into that space instead. I bet |
