Release 2022-05-30 with Lk 5.15, Lk 5.18 and Bullseye

This release contains a debian bullseye rootfs (fstab for usb) with kernel 5.15. Additionally kernel 5.18 is provided.

Release 1.5 with Debian Bullseye and lk5.11

This release has lk5.11 and debian bullseye for testing.

Contains a fix for fstab and drops support for prepackaged gcc. Use the apt version.

Release 1.4 with Debian Buster and lk5.10

Not much new in this release. Mainly improved some network handling, updated to newest LK5.10.y.

Also all parts are now downloadable seperately. So if you only want the modules & image no need to grab everything.
(Ofc the rootfs still contains everything to boot, so no need to manually insert anything there).

Release 1.3 with debian buster and lk5.10

This contains prebuilt lk5.9 and lk5.10, buster, uRamdisk. Tested on wdmc boot with usb.

Release 1.2 with debian buster rootfs, prebuilt LK5.8

This release contains the linux kernel 5.8, modules and debian buster with applied tweaks.

Release 1.1 with debian buster rootfs, prebuilt LK5.6

This release contains the linux kernel 5.6, modules and debian buster with applied tweaks.

To use this on your wdmc you'll have to decide wether to use a USB drive or the internal drive.

USB:

• create a FAT32 partition (this will be used to boot, will be called sdb1)
• create a ext4 partition (this will be used as root, will be called sdb2)
• create a folder called 'boot' on sdb1
• move the files from release/boot into the boot folder on sdb1. Rename/link the uImage-5.6 file to uImage. Make sure both the uImage and uRamdisk are executable
• extract the buster-rootfs.tar.gz on the sdb2 partition
• copy the release/lib/ folder onto the sdb2 partition (to add the 5.6 modules)
• adjust sdb2/etc/fstab to fit your needs (will probably be ok)
• boot wdmc with usb stick, root password is '1234', configure/add packages as needed

Internal:

• create ext4 partition (this should be the third, so /dev/sda3)
• copy the folder from release/boot into sda3. Rename/link the uImage-5.6 file to uImage. Make sure both the uImage and uRamdisk are executable
• extract the buster-rootfs.tar.gz on the sda3 partition
• copy the release/lib/ folder onto the sda3 partition (to add the 5.6 modules)
• adjust sda3/etc/fstab to fit your needs (you don't need seperate root / boot folders, so adjust this)
• boot wdmc, root password is '1234', configure/add packages as needed

I suggest starting with USB stick, because this requires no changes on the internal harddisk.

If you need custom initramfs or different kernel settings, check the code and build neccessary files yourself.
