I am trying to upgrade to Yocto Warrior using the master branch of meta-mender. I have it fully working on both grub (x86) and u-boot (raspberrypi). There is only one problem with the `mender -commit` when booting in the warrior version: ```auto time="2019-07-26T21:31:07Z" level=info msg="Loaded configuration file: /etc/mender/mender.conf" module=config time="2019-07-26T21:31:07Z" level=info msg="No dual rootfs configuration present" module=main time="2019-07-26T21:31:07Z" level=info msg="Update Module path \"/usr/share/mender/modules/v3\" could not be opened (open /usr/share/mender/modules/v3: no such file or directory).

I can upgrade and downgrade from Yocto thud without any errors. These configuration seems to be generated from mender.inc or mender-setup.bbclass. I am not sure why under the master branch they are not getting added to the mender.conf file. ---

Hi @cveilleux It’s great that you got it working based on warrior with a raspberry pi! I’m trying the same but am having some trouble. Is your project open-source so I could look at how you did it? Regarding your question, could you look into your /data parition. There you should also find a set of config files, for me it’s in /data/mender/mender.conf. So whenever I run mender, I always add the `-data /data/mender -config /data/mender/mender.conf` args. ---

Hi, Thanks for the tip. Yes, I could point to a custom mender.conf. Previous builds would automatically set the RootfsPart settings, so something must have changed with warrior. Please find attached my patch to make meta-mender build with poky and meta-raspberrypy warrior branches. I am applying it on top of meta-mender master. I simply declared layer compatibility and removed a u-boot patch that is no longer required (upstreamed). ```auto diff --git a/meta-mender-core/conf/layer.conf b/meta-mender-core/conf/layer.conf index 855dc21..41a74f0 100644 --- a/meta-mender-core/conf/layer.conf +++ b/meta-mender-core/conf/layer.conf @@ -17,5 +17,5 @@ BBFILE_PRIORITY_mender = "6" INHERIT += "mender-setup" -LAYERSERIES_COMPAT_mender = "thud" +LAYERSERIES_COMPAT_mender = "thud warrior" LAYERDEPENDS_mender = "core" diff --git a/meta-mender-core/recipes-bsp/u-boot/u-boot-mender-common.inc b/meta-mender-core/recipes-bsp/u-boot/u-boot-mender-common.inc index f4f17df..3c1f08d 100644 --- a/meta-mender-core/recipes-bsp/u-boot/u-boot-mender-common.inc +++ b/meta-mender-core/recipes-bsp/u-boot/u-boot-mender-common.inc @@ -17,7 +17,6 @@ FILESEXTRAPATHS_prepend := "${THISDIR}/patches:${THISDIR}/files:" SRC_URI_append_mender-uboot = " file://0001-Add-missing-header-which-fails-on-recent-GCC.patch" SRC_URI_append_mender-uboot = " file://0002-Generic-boot-code-for-Mender.patch" SRC_URI_append_mender-uboot = " file://0003-Integration-of-Mender-boot-code-into-U-Boot.patch" -SRC_URI_append_mender-uboot = " file://0006-env-Kconfig-Add-descriptions-so-environment-options-.patch" SRC_URI_append_mender-uboot = "${@bb.utils.contains('MENDER_UBOOT_AUTO_CONFIGURE', \ '1', \ diff --git a/meta-mender-raspberrypi/conf/layer.conf b/meta-mender-raspberrypi/conf/layer.conf index ed4626e..750fef0 100644 --- a/meta-mender-raspberrypi/conf/layer.conf +++ b/meta-mender-raspberrypi/conf/layer.conf @@ -14,7 +14,7 @@ BBFILE_PRIORITY_mender-raspberrypi = "10" LAYERDEPENDS_mender-raspberrypi = "mender raspberrypi" -LAYERSERIES_COMPAT_mender-raspberrypi = "thud" +LAYERSERIES_COMPAT_mender-raspberrypi = "thud warrior" # Raspberry Pi doesn't work with GRUB currently. _MENDER_IMAGE_TYPE_DEFAULT_rpi = "mender-image-sd" ``` ---

As far as I know the mender client should automatically “probe” a couple of default locations for the `mender.conf` file, e.g `/etc/mender/mender.conf` `/var/lib/mender/mender.conf` (same as /data/mender/mender.conf by default in Yocto) And the additional args should not be needed. Can you check if these files are in place? Can you also share which version of the Mender client you are running?
