## CROSS COMPILATION TOOLS
|
||||||
|
Installing cross GCC compilation tools (for the X86 machine, not target ARM). Includes binutils.
|
||||||
|
|
||||||
|
* OPTION 1: from repository (Devuan example)
|
||||||
|
`sudo apt-get install gcc-arm-none-eabi`
|
||||||
|
|
||||||
|
* OPTION 2: proportioned by odroid
|
||||||
|
```
|
||||||
|
wget http://odroid.in/guides/ubuntu-lfs/arm-unknown-linux-gnueabi.tar.xz
|
||||||
|
tar -Jxf arm-unknown-linux-gnueabi.tar.xz
|
||||||
|
```
|
||||||
|
|
||||||
|
Name of "_CROSS_COMPILE_" variable will change depending on the choosen option. This guide assumes from repository and therefore will equal to "_CROSS\_COMPILE=arm-none-eabi-_"
|
||||||
|
|
||||||
|
|
||||||
|
## PARTITIONING
|
||||||
|
* clear the section for the bootloader
|
||||||
|
`dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=8`
|
||||||
|
* enter fdisk
|
||||||
|
`fdisk /dev/mmcblk0`
|
||||||
|
* help
|
||||||
|
`m`
|
||||||
|
* create new MBR partition table
|
||||||
|
`o`
|
||||||
|
* create boot partition
|
||||||
|
`n`
|
||||||
|
* assign start of boot partition at the end of the bootloader space
|
||||||
|
`3073`
|
||||||
|
* assign end of boot partition
|
||||||
|
`+128M`
|
||||||
|
* create root partition
|
||||||
|
`n`
|
||||||
|
* press enter twice to use the rest of the disk
|
||||||
|
Make
|
||||||
|
`mkfs.<ROOT_FILESYSTEM> /dev/sda2`
|
||||||
|
* Make boot filesystem according to supported bootloader or just "_mkfs.vfat_" if on UEFI.
|
||||||
|
`mkfs.<BOOTLOADER_FILESYSTEM> /dev/sda1`
|
||||||
|
|
||||||
|
|
||||||
|
## BOOTLOADER
|
||||||
|
Minimum 3072 bytes free at the start of the drive and before the boot partition.
|
||||||
|
|
||||||
|
* VERSION 1: compile
|
||||||
|
```
|
||||||
|
git clone https://github.com/hardkernel/u-boot.git -b odroidc2-v2015.01
|
||||||
|
cd u-boot
|
||||||
|
make ARCH=arm64 CROSS_COMPILE=arm-none-eabi- odroidc2_defconfig
|
||||||
|
make -j4
|
||||||
|
cd boot
|
||||||
|
```
|
||||||
|
|
||||||
|
* VERSION 2: download and extract the binary
|
||||||
|
```
|
||||||
|
wget http://odroid.in/guides/ubuntu-lfs/boot.tar.gz # http://dn.odroid.com/S905/BootLoader/ODROID-C2/c2_boot_release_ubuntu.tar.gz
|
||||||
|
tar -zxvf boot.tar.xz
|
||||||
|
cd boot
|
||||||
|
```
|
||||||
|
|
||||||
|
* flash bootloader
|
||||||
|
```
|
||||||
|
chmod +x sd_fusing.sh
|
||||||
|
./sd_fusing.sh /dev/sdX
|
||||||
|
```
|
||||||
|
* notice the target is the device NOT any partition
|
||||||
|
* set resolution by editing file root/boot/boot.ini
|
||||||
|
* might want to comment-out the display-autodetect option
|
||||||
|
|

|
|
||||||
|

||||||
|

|
||||||
|
|
||||||
|

||||||
|

||||||
|
* OPTION 2: making kernel config
|
||||||
|
```
|
||||||
|
