Everything this document is about is how to setup the sd card that finally is inserted to the banana. So lets start:
|
||||
|
||||
The sd card contains the following:
|
||||
* Pre-Loader
|
||||
* u-boot
|
||||
* vfat: boot (`/dev/mmcblk1p1`)
|
||||
* ext4: root (`/dev/mmcblk1p2`)
|
||||
* ...
|
||||
|
||||
## Pre-Loader:
|
||||
|
||||
...!!!
|
||||
|
||||
## u-boot:
|
||||
|
||||
...!!!
|
||||
|
||||
## boot-partition:
|
||||
|
||||
Contains:
|
||||
|
||||
```bash
|
||||
/zImage
|
||||
/dts/mt7623n-bananapi-bpi-r2.dtb
|
||||
```
|
||||
|
||||
and further images (eg diifferent kernel versions etc...)
|
||||
|
||||
### how to create these files:
|
||||
(because they are not available anywhere, at least not for the most recent kernel. The most recent version provided by some debain derivates is 4.4 or 4.14... too old for my taste!)
|
||||
|
||||
```bash
|
||||
git clone https://github.com/mbgg/linux-mediatek.git
|
||||
cd linux-mediatek
|
||||
git checkout <commit_I_recommend>
|
||||
cp <this_repo>/kernel/linux-mediatek-<commit_hash>.config .config
|
||||
cp <this_repo>/kernel/mt7623n-bananapi-bpi-r2.dts arch/arm/boot/dts
|
||||
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- oldconfig
|
||||
make -j4 ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- zImage dtbs
|
||||
mkdir boot.setup
|
||||
mount /dev/mmcblk0p1 boot.setup
|
||||
cp arch/arm/boot/zImage boot.setup
|
||||
cp arch/arm/boot/dts/mt7623n-bananapi-bpi-r2.dtb boot.setup/dts
|
||||
sync
|
||||
umount boot.setup
|
||||
rmdir boot.setup
|
||||
```
|
||||
|
||||
## root-partition:
|
||||
|
||||
If you did no mistake so far (...) this should be the easiest part:
|
||||
There are two possibilities:
|
||||
* Use the provided image [name], dd it to your root partition, boot into this root and update and customaize the system
|
||||
* dd the image to a temporary partition, boot into it, and setup the root partition using pacstrap (you dont need the linux or linux-firmware package, you already cared about these parts in the previous section)
