Motorola XT894 >> Alpine
安裝系統
參考資訊：
1. alpine
步驟如下：
1. 燒錄kexecboot
2. 製作系統
$ sudo apt-get install qemu-user-static -y
$ cd
$ wget -P archives/basic_rootfs/alpine/ -c http://dl-cdn.alpinelinux.org/alpine/v3.11/releases/armv7/alpine-minirootfs-3.11.3-armv7.tar.gz
$ git clone https://github.com/omerlle/droid4-bringup.git archives/droid4_bringup
$ git -C archives/droid4_bringup/ checkout alpine
$ wget -c https://github.com/TI-ECS/bt-firmware/raw/master/TIInit_10.6.15.bts -P archives/firmware/ti-connectivity
$ export droid_rootfs="$PWD/rootfs/alpine/3.11.3_armv7"
$ mkdir -p ${droid_rootfs}
$ sudo tar -xzf archives/basic_rootfs/alpine/alpine-minirootfs-3.11.3-armv7.tar.gz -C ${droid_rootfs}/
$ sudo rsync -a --chown=root:root archives/droid4_bringup/overlay/ ${droid_rootfs}
$ sudo cp /etc/resolv.conf ${droid_rootfs}/etc/
$ sudo cp -a /usr/bin/qemu-arm-static ${droid_rootfs}/usr/bin/
$ sudo mount -t proc /proc ${droid_rootfs}/proc
$ sudo mount -o bind /dev ${droid_rootfs}/dev
$ sudo chroot ${droid_rootfs} sh

$ sudo umount ${droid_rootfs}/dev
$ sudo umount ${droid_rootfs}/proc
$ sudo cp archives/firmware/ti-connectivity/TIInit_10.6.15.bts ${droid_rootfs}/lib/firmware/ti-connectivity/
燒錄到記憶卡(zImage、omap4-droid4-xt894.dtb需先編譯好)：
$ export sdcard="mmcblk0"
$ set -u
$ mount | grep /dev/$sdcard | cut -d ' ' -f 3 | xargs umount echo "1 : start= 2048, size= 102400, type=83 2 : start= 104448, size= 4194304, type=83 3 : start= 4298752, size= $(($(cat /sys/block/$sdcard/size)-4298752)), type=83" | sudo sfdisk /dev/$sdcard
$ sudo partprobe /dev/${sdcard}
$ sudo mkfs.vfat /dev/${sdcard}p1 -n BOOT
$ sudo mkfs.ext4 /dev/${sdcard}p2 -L rootfs
$ sudo mkfs.vfat /dev/${sdcard}p3 -n USER_DATA
$ set +u
$ mkdir mnt
$ sudo mount /dev/${sdcard}p1 mnt
$ sudo mkdir -p mnt/boot
$ sudo rsync --chown=root:root archives/droid4_bringup/boot/boot.cfg mnt/boot
### sudo rsync --chown=root:root zImage omap4-droid4-xt894.dtb mnt/boot
$ sync
$ sudo umount mnt
$ sudo mount /dev/${sdcard}p2 mnt
$ sudo rsync --delete -av ${droid_rootfs}/ mnt/
### sudo make -j8 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=mnt/
$ sync
$ sudo umount mnt
$ sudo mount /dev/${sdcard}p3 mnt
$ sudo install -d mnt/droid4/modem/{dynamic_data,logs}
$ sudo mv ${droid_rootfs}/tmp/modem.db mnt/droid4/modem/dynamic_data/
$ sync
$ sudo umount mnt
P.S. 插入XT894後開機即可。
