![]() ![]() After this you can (optionally) dd the new android_boot.img back to the android_boot partition to make the change permanent. The easiest way to test the new image is using fastboot, boot the tablet into Android and connect it to the PC, then run:Īnd then from an "adb shell" do "cat /fstab" verify that the "verify" option is gone now. initrd.imgĪbootimg -u android_boot.img -r initrd.img after this update android_boot.img like this:įind. Now edit the fstab file and remove "verify" from the line for the system partition. On this computer extract the file and then the initrd like this: Now make an image of the partition by running e.g.:ĭd if=/dev/mmcblk1p3" of=android_boot.imgĪnd then copy the "android_boot.img" file to another computer. Replacing the ? for the mmcblk number for the internal eMMC and then for # is 1 to n, until one of the partitions is reported as having 'PARTLABEL="android_boot"', usually "mmcblk?p3" is the one you want, so you could try that first. Note booting a regular Linux distro may cause the Android "system" partition to get auto-mounted after which dm-verity checks will fail! Once we have a regular Linux distro running step 1 is to find out which partition is the android_boot partition to do this as root run: After booting from an USB stick with the relevant grub binary installed as "EFI/BOOT/BOOTX64.EFI" or "BOOTIA32.EFI", entering theįollowing command on the grub cmdline will unlock the bootloader:ĭisabling dm-verity support is pretty easy on these devices because they can just boot a regular Linux distro from an USB drive. Like with some of my previous adventures changing hidden BIOS settings, this EFI variable is hidden from the OS as soon as the OS calls ExitBootServices, but we can use the same modified grub to change this EFI variable. Luckily there is an alternative, kernelflinger checks a "OEMLock" EFI variable to see if the device is locked or not. I got the unlock yes/no dialog, and could move between yes and no, but I could not actually confirm the choice). Sometimes the Android-X86 boot-loader (kerneflinger) is locked and the standard "Developer-Options" -> "Enable OEM Unlock" -> "Run 'fastboot oem unlock'" sequence does not work (e.g. If you have a screen connected to the Generic x86-64 system, after a minute or so the Home Assistant welcome banner will appear in the console.For the hw-enablement for Bay- and Cherry-Trail devices which I do as a side project, sometimes it is useful to play with the Android which comes pre-installed on some of these devices. Plug in an Ethernet cable that is connected to the network.Ubuntu), shut it down and remove the live operating system USB device. In my experience, u-boot is built for a single specific embedded platform. If you used a live operating system (e.g. make clean make coreboot-x86config make is more likely to be useful to you. ![]() If you used your desktop system to write the HAOS image directly to a boot medium like an S-ATA SSD, connect this back to your Generic x86-64 system. If you are having issues with Balena Etcher, try version 1.10. The Unified Extensible Firmware Interface Specification (UEFI) 1 has become the default for booting on AArch64 and x86 systems.When Balena Etcher has finished writing the image, you will see a confirmation.Select Flash! to start writing the image.Do not format the SD card after installing, even if prompted to. Select the boot medium (storage device) you want to use for your installation. Install the image to your SD card, then plug everything in to your Raspberry Pi and boot it up.When Balena Etcher has downloaded the image, click Select target.Paste the URL for the Generic x86-64 image into Balena Etcher and select OK.Select and copy the URL or use the “copy” button that appear when you hover it. Next, we need to write the Home Assistant Operating System image to the “boot medium”, which is the medium your x86-64 hardware will boot from when it is running Home Assistant. To enter the BIOS, start up your x86-64 hardware and repeatedly press the F2 key (on some systems this might be Del, F1 or F10). However, the options should still be present and named similarly. The BIOS menu will likely look different on your system. The following screenshots are from a 7th generation Intel NUC system. To boot Home Assistant OS, the BIOS needs to have UEFI boot mode enabled and Secure Boot disabled. Configure the BIOS on your x86-64 hardware There are two ways to do this listed below. You will need to configure your Generic x86-64 PC to use UEFI boot mode, then write the HAOS (Home Assistant OS) disk image to your boot medium. Pretty much all systems produced in the last 10 years support the UEFI boot mode. I have attempted to install as root uboot-tools using the command dnf install uboot-tools but this is not available. ![]() The system must be 64-bit capable and able to boot using UEFI. I want use the command mkimage in my Centos 8. This guide assumes that you have a dedicated Generic x86-64 PC (typically an Intel or AMD-based system) available to exclusively run Home Assistant Operating System.
