Unofficial reMarkable Linux Kernel
UNDER DEVELOPMENT
This kernel is for the reMarkable2 epaper tablet.
Differences
This is a small fork of the upstream reMarkable kernel from the manufacturer.
- Adds kernel patch from here: https://remarkablewiki.com/tech/rm2_otg_pogo
Build
Build thine kernel thusly:
git clone https://spacecruft.org/redonkable/remarkable-linux
cd remarkable-linux
# should already be on this branch, but check it out:
git checkout redonkable
ARCH=arm CROSS_COMPILE=arm-none-eabi- make zero-sugar_defconfig
ARCH=arm CROSS_COMPILE=arm-none-eabi- make -j`nproc`
ARCH=arm CROSS_COMPILE=arm-none-eabi- make modules_install INSTALL_MOD_PATH=./tmp
rm -rf tmp/lib/modules/*/build tmp/lib/modules/*/source
Install files thusly. Symlink them later, or change fw_env variables.
# Kernel modules
scp -pr tmp/lib/modules/* root@10.11.99.1:/lib/modules/
# Kernel
scp -p arch/arm/boot/zImage root@10.11.99.1:/boot/zImage-4.14.78
# DTB
scp -p arch/arm/boot/dts/zero-sugar.dtb root@10.11.99.1:/boot/zero-sugar.dtb-4.14.78
Log in and set symlinks to new kernel seteup.
ssh root@10.11.99.1
cd /boot
mv zImage zImage.bak
ln -s zImage-4.14.78 zImage
mv zero-sugar.dtb zero-sugar.dtb.bak
ln -s zero-sugar.dtb-4.14.78 zero-sugar.dtb
cd /lib/modules
mv 4.14.78 4.14.78.bak
# Note, git tag may vary, something like:
ln -s 4.14.78-g2682167b2d00-dirty 4.14.78
Then power off, power back up.
