 # Misc Notes
 
-## Building BSP kernel
-
-In Ubuntu 18.04 Docker with packages `repo git ssh make gcc libssl-dev liblz4-tool expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib unzip device-tree-compiler python-pip ncurses-dev python-pyelftools bc time rsync`.
-
-I think the closest device to the pinenote is 
-```
-./build.sh device/rockchip/rk356x/BoardConfig-rk3566-evb2-lp4x-v10.mk kernel
-```
-You can edit the `.mk` to increase the number of build threads.
-To use the eink, we probably need to edit the dts to include `rk3566-evb2-lp4x-v10-eink.dts`, which is currently seems unused?
-
-## Building U-Boot
-
-In Ubuntu 18.04 Docker with packages `gcc-aarch64-linux-gnu make gcc python3-pyelftools bc`.
-```
-export CROSS_COMPILE=aarch64-linux-gnu-
-make rk3566-quartz64_defconfig
-./make.sh
-```
-
-## Custom Logo
-
-The PineNote has a `logo` partition containing images displayed by uboot for when the device is off.
-There exists a tool called `bmp2gray.c` in the downstream uboot, but it does not appear to quite match the partition.
-So I wrote my own [logotool](logodump/logotool.c) to convert the logo partition to PNGs and back.
-While I haven't created custom logos, the logotool is able to recreate the logo partition exactly (see the [test.sh](logodump/test.sh) script).
