I am having issue to use grub environment block to switch partition. I am using the logic you suggested. But I am not sure the GRUB is looking for grubenv in my case. How we can set grub where to look for grubenv block.\n\nAlso If you used yocto for this build. Any suggestion to get grubenv by default in image would be helpful.\n\nThanks,\nR","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=googlegroups.com\n\t(client-ip=2607:f8b0:400c:c05::23e;\n\thelo=mail-vk0-x23e.google.com;\n\tenvelope-from=swupdate+bncbc52v2v6wuerbints7jakgqejl4rxai@googlegroups.com;\n\treceiver=)","ozlabs.org;

Ubuntu uses /etc/grub.d/\nand it has its own grub.cfg. Variables are interpreted according to this\nimplementation. You have to rewrite grub.cfg to evaluate the variables\nfrom grubenv.\n\nAnyway, updating Ubuntu is quite far away from SWUpdate's goal. If you\nhave an embedded board based on X86, and you have GRUB on it, you have\nto provide your grub.cfg for working - see in Yocto.\n\nIn Ubuntu, variables are overwritten by Ubuntu's handling, that is by\nregenerating grub.cfg based on /etc/grub.d/*.\n\n> In any case, grub2 looks like workaround for EFI system. Boards with EFI\n> can use EFI environment directly, without grub-layer.\n\nDo not forget that this was thought for Desktop / PCs, and not for\nembedded system, and updating the environment is not power-off safe as\nfar as I know.\n\n> \n> P.S. Many guides recommend use / etc / default / grub instead of writing\n> custom configs.\n\nOf course - update of a Linux Distro is different as on an embedded\nsystems and Ubuntu has its own set of rules to drive the bootloader.\n\nBest regards,\nStefano Babic\n\n> \n> \n> пятница, 29 декабря 2017 г., 11:35:42 UTC+3 пользователь Stefano Babic\n> написал:\n> \n> Hi Roman, R,\n> \n> On 29/12/2017 07:31, Roman Kalashnikov wrote:\n> > Hi!\n> >\n> > I was working with efi-system too.

I get\ngrub2 working fine without any hack with the yocto build.\nI am planning to add examples in swupdate repo and meta-swupdate. To save\nothers hours in debugging same things I did.\n\nHere is the brief description of what steps I did.\n\n1. In yocto grub2.0 build. it is preparing image without the\nloadenv module. That is the reason that why I was failing to switch rootfs.\nI added new append file to update grub build to be compatible with swupdate.\n\n# Update grub to generate image with environment block support\n# and create default grub env file with default boot option.\n\nGRUB_BUILDIN = \"boot linux ext2 fat serial part_msdos part_gpt normal\nefi_gop iso9660 search loadenv\"\n\nGRUB_DEFAULT_BOOT_ENTRY ?= \"boot\"\n\ndo_deploy_append() {\n# Create grub env block with default value.\ngrub-editenv grubenv create\ngrub-editenv grubenv set default=${GRUB_DEFAULT_BOOT_ENTRY}\ninstall -m 644 ${B}/grubenv ${DEPLOYDIR}\n}\n\n2. We also need to update grub-efi.bbclass to copy grubenv in EFI folder\nalong bootxXX.efi file.\n3. When we prepare bootXX.efi, add \"load_env\" command along with other\ndefault commands in config.\n\nsearch.file ($cmdpath)/EFI/BOOT/grub.cfg root\nset prefix=($root)/EFI/BOOT\nload_env\n\n4. Update wks or image prepare script to update grub.cfg properly. (I am\nworking on this part). Once I don't with this talk I will add all\nwell-formated steps in a readme.\n\n@\nStefano Babic\n @Otavio\nNeed a piece of advice, Can we add these append file to meta-swupdate layer\nso others can easily start working with GRUB bootloader in the yocto\nbuild? Or keep them as information in doc?\n\nThanks,\nRahul K\n\n\n\nOn Fri, Dec 29, 2017 at 3:47 PM Otavio Salvador <\notavio.salvador@ossystems.com.br> wrote:\n\n> On Fri, Dec 29, 2017 at 7:27 AM, Roman Kalashnikov \n> wrote:\n> > Yes, i have \"load_env\" in my grub.cfg.\n> > It was tested in Ubuntu 16.04.3 and grub just ignore most of params (f.e.\n> > next boot entry, timeouts, e.t.c.).\n> > In any case, grub2 looks like workaround for EFI system.
