240526-01 - experimental tiny alpine image for the milk v duo 64mb riscv64 sbc

• this is just an experimental testing image
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/milk_v_duo
• based on alpine edge riscv64
• the v5.10.4 milk-v legacy kernel is used
• no display or gpu support as the kernel does not easily support any display hardware and the devices do not have a gpu
• it is intended only for running the system from an sd card
• username/password is as usual linux/changeme
• in case an image should not properly boot on your system, then please add a comment here: #130
• in case everything is working well, feel free to leave a comment here: #141

240525-01 - experimental tiny alpine image for bouffalo lab bl808 based riscv64 mcu devices like the sipeed m1s dock or the pine64 ox64

• this is just an experimental testing image
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/bouffalo_lab_bl808
• based on alpine edge riscv64
• the v6.5.11 close to mainline kernel used is based on the openbouffalo project kernel
• no display or gpu support as the kernel does not yet support any display hardware and the devices do not have a gpu
• it is intended only for booting the bootloader from the builtin flash and running the system from an sd card
• username/password is as usual linux/changeme

240521-01 - experimental debian sid image for the banana pi f3 riscv64 sbc

• this is just an experimental testing image
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/bpi_f3
• based on the debian sid/unstable riscv64 port
• the v6.1.15 kernel used is based on the legacy bpi f3 kernel tree
• framebuffer console is used, also for xorg
• no gpu support as i'll not touch this until a proper open source driver is available - the legacy img stuff is just a waste of time to play around with ...
• has some features typical for the images here: btrfs rootfs with zstd compression, zswap with zstd compression, mgrlu enabled by default
• it is intended only for booting and running from an sd card (emmc not tested and will most probably not work)
• username/password is as usual linux/changeme
• in case an image should not properly boot on your system, then please add a comment here: #130

240519-01 - experimental debian sid image for the starfive visionfive2 riscv64 sbc

• this is just an experimental testing image, actually an updated version of the one from last year which is now using the regular debian sid repos as riscv64 is finally included there now
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/starfive_visionfive2
• based on the debian sid/unstable riscv64 port
• the v5.15 kernel used is based on VF2_v2.10.4 of the starfive visionfive2 kernel tree and some patches from the icenowy star64 kernel tree - it is still the old kernel from last year as it works fine and if one wants to play around with special features building an own kernel will be required anyway
• framebuffer console added (part of the patches mentioned above)
• a v5.15 backport of mglru added (multigen lru mm patches, which were merged into v6.1 mainline and improve performance especially in low memory situations)
• no gpu support as i'll not touch this until a proper open source driver is available - the legacy img stuff is just a waste of time to play around with ...
• has some features typical for the images here: btrfs rootfs with zstd compression, zswap with zstd compression, mgrlu enabled by default
• please switch the dip switches on the board to "sd", i.e. upper one (marked rgpio_1) to 0 (marked ON on the dip switch, i.e. default setting) and lower one (marked rgpio_0) to 1 (marked 2 on the dip switch, i.e. oposite to the default setting) to boot directly from the sd card as this image has sbi/u-boot included in its boot blocks (taken from the 202302 starfive debian image)
• username/password is as usual linux/changeme

240112-02 - experimental debian bookworm image for snapdragon 835/msm8998 based laptops like the asus novago

• for more information see: https://github.com/hexdump0815/imagebuilder/blob/main/systems/snapdragon_835/readme.md
• those images are very much work in progress and only ment for others who might want to help brining up linux support for such systems - they are basically running, but a lot of things are not working yet or not properly yet, so they are really nothing for daily use - use them at your own risk as the bringup of those systems is still in its very early stages
• v6.6.9 kernel from linux-stable (no longer from some special msm8998 repo)
• this image is essentially just a move to a newer kernel (v6.6 lts) and it has a few little fixes and improvements here and there, no major progress otherwise
• currently supported are the asus novago, someone booted the last image successful on a lenovo miix 630 and it might also work on the hp envy x2 (there are entries for all three in the grub menu - please always select the correct entry for your device as booting with the wrong device tree might harm the device worst case)
• WARNING: except if you really really really know what you are doing, do not do anything with this internal storage and especially do not simply try to install linux on any of those storage devices as it is very easily possible to completely brick the device by messing up those partitions without any option to recover from that situation - even if the internal storage is accessible, please only run linux from sd card or usb!

240112-01 - experimental debian bookworm image for aarch64/arm64 chromebooks based on the mediatek mt8186 soc (corsola)

• this is just an experimental testing image to be able to get started with linux on this type of machines
• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/chromebook_corsola
• kernel version used: around v6.7.0-rc8, based on the collabora chromeos kernel mainline integration tree for the mediatek chromebooks
• minimal testing has been done on a magneton chromebook (lenovo cb ideapad slim 3)
• debian bookworm only for now
• gpu now supported via panfrost/mesa
• audio is not working intentionally - this needs some careful (i.e. to not destroy speakers or ears) extra work i guess

240107-01 - experimental debian bookworm and ubuntu jammy images for snapdragon 7c based laptops like the samsung galaxy book go and acer aspire 1

• for more information see: https://github.com/hexdump0815/imagebuilder/blob/main/systems/snapdragon_7c_woa/readme.md
• this image is very much work in progress and only ment for others who might want to help brining up linux support for such systems - they are basically running, but a lot of things are not working or not properly working yet, so they are really nothing for daily use - use them at your own risk as the bringup of those systems is still in its very early stages
• currently supported are the samsung galaxy book go and the acer aspire 1, but the image can also be used as a starting point for adding support for other similar devices
• v6.6.9 kernel with changes from the travmurav acer aspire 1 tree and ufs support from ungeskriptet
• the grub menu has entries for samsung galaxy book go (default) and acer aspire 1 (second entry) - please always select the correct entry for your device as booting with the wrong device tree might harm the device worst case
• the touchpad is working now
• a new somewhat cleaned up draft dts is now used for the samsung galaxy book go
• internal ufs storage is now enabled and accessible on the samsung galaxy book go and it is usually visible as 6 scsi devices from sda to sdf
• WARNING: except if you really really really know what you are doing, do not do anything with this internal storage and especially do not simply try to install linux on any of those storage devices as it is very easily possible to completely brick the galaxy book go by messing up those partitions without any option to recover from that situation - even if the internal storage is accessible now, please only run linux from sd card or usb!

• see: https://github.com/hexdump0815/imagebuilder/tree/main/systems/allwinner_h3
• kernel version used: v6.1.51
• this is for nearly 10 year old hardware, so do not expect wonders regarding the performance :)
• debian bookworm only, i have no real plan to create jammy images for these devices - in case an ubuntu jammy is seriously required, maybe have a look at: #129

• no changes around the kernel, just a fresh bookworm image with the changes and improvments which went into it to have a more up to date os available again
