全志t113在主线上的debian,rgb屏幕和触摸驱动

#全志t113在主线上的debian,rgb屏幕和触摸驱动
闲来无事折腾一下linux，对于全志所有芯片的主线支持情况在 sunxi-wiki 上有着详细的记录，可以看出社区在linux6.0之后对D1/D1S/T113系列芯片的支持做的很不错。

##编译主线u-boot，zimage
预装编译环境

1
apt install gcc-arm-linux-gnueabihf debootstrap

先创建一个文件夹，并下载好对应的库

mkdir linux
mkdir bin # 用于存放二进制文件
mkdir mdir # 用于挂载
cd linux
git clone --depth=1 https://github.com/u-boot/u-boot
git clone --depth=1 https://github.com/torvalds/linux

创建一个 boot.cmd 脚本

setenv bootargs  mem=128M cma=72M console=ttyS3,115200 root=/dev/mmcblk0p2 rootwait panic=10
fatload mmc 0:1 0x43000000 ${fdtfile} || load mmc 0:1 0x43000000 boot/${fdtfile}
fatload mmc 0:1 0x42000000 zImage || load mmc 0:1 0x42000000 boot/zImage
bootz 0x42000000 - 0x43000000

创建一个 build.sh 脚本，用于方便提取所需文件

cd u-boot
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mangopi_mq_r_defconfig
make -j6 ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=sun8i-t113s-mangopi-mq-r-t113
cd ../linux
make  ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- sunxi_defconfig
make -j6  ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- zImage dtbs modules
cd ..

cp u-boot/u-boot-sunxi-with-spl.bin bin/
cp linux/arch/arm/boot/zImage bin/
cp linux/arch/arm/boot/dts/allwinner/sun8i-t113s-mangopi-mq-r-t113.dtb bin/

mkimage -C none -A arm -T script -d boot.cmd bin/boot.scr

编译时只需要source build.sh 就可以在bin中可以得到所需文件，使用fdisk对sd卡进行分区，先按d删除所有区，再按n新建一个分区，用来存放zimage dtb之类的文件，偏移输入8192，大小输入+16M，再按n新建一个分区，用来存放linux文件系统，建议大小大于1G，偏移量输入40960，再按t进行分区，第一区为0b，第二区为83，最后按w退出。
格式化所有分区

sudo mkfs.fat /dev/sda1
sudo mkfs.ext4 /dev/sda2

编写一个writeboot.sh，用于将所image和uboot刷入sd卡

sudo dd if=bin/u-boot-sunxi-with-spl.bin of=/dev/sda bs=1024 seek=8
sudo mount /dev/sda1 mdir
sudo cp zImage mdir/
sudo cp sun8i-t113s-mangopi-mq-r-t113.dtb mdir/
sudo cp boot.scr mdir/
sudo cp uboot.env mdir/
sudo umount /dev/sda1 mdir

接下来source writeboot.sh 就可以将sd卡插入t113验证uboot和kernel是否工作，由于还没有文件系统，会在最后卡住。
##debootstrap创建debian文件系统
先创建一个用于挂载的ch-mount.sh

#!/bin/bash

function mnt() {
    echo "MOUNTING"
    sudo mount -t proc /proc ${2}/proc
    sudo mount -t sysfs /sys ${2}/sys
    sudo mount -o bind /dev ${2}/dev
    sudo mount -o bind /dev/pts ${2}/dev/pts		
    sudo chroot ${2}
}

function umnt() {
    echo "UNMOUNTING"
    sudo umount ${2}/proc
    sudo umount ${2}/sys
    sudo umount ${2}/dev/pts
    sudo umount ${2}/dev

}

if [ "$1" == "-m" ] && [ -n "$2" ] ;
then
    mnt $1 $2
elif [ "$1" == "-u" ] && [ -n "$2" ];
then
    umnt $1 $2
else
    echo ""
    echo "Either 1'st, 2'nd or both parameters were missing"
    echo ""
    echo "1'st parameter can be one of these: -m(mount) OR -u(umount)"
    echo "2'nd parameter is the full path of rootfs directory(with trailing '/')"
    echo ""
    echo "For example: ch-mount -m /media/sdcard/"
    echo ""
    echo 1st parameter : ${1}
    echo 2nd parameter : ${2}
fi

使用debootstrap创建文件系统并挂载进sda2

sudo mount /dev/sda2 mdir/
sudo debootstrap --arch=armhf sid mdir https://mirrors.tuna.tsinghua.edu.cn/debian/
chmod 777 ch-mount.sh

接下来就是初始化配置下载一些库

至此，你的debian系统就设置完成了，如国你想保存下来，只需sudo tar -cvf t113-debian.tar mdir/，接下来将sd卡插入t113，就可以进入debian系统使用了，

##drm驱动和input子系统
t113使用sun4i的drm驱动，已在debian中通过apt下载好，如果在譬如busybox中则需使用mesa源码交叉编译，mesa库编译环境挺麻烦的，建议还是能用包管理器下载就用包管理器下载。
修改位于linux/arch/arm/boot/dts/allwinner/sun8i-t113s-mangopi-mq-r-t113.dts的设备树，

panel 驱动使用你实际屏幕的参数，再次修改linux/t113-s3/linux/arch/arm/configs/sunxi_defconfig向其中添加

CONFIG_EXPERT=y
CONFIG_TOUCHSCREEN_GOODIX=y

重新编译烧录，在命令行中使用glmark2-drm即可看到熟悉的小马
image
当然，这个测试是跑不完的，因为t113s3只有128m内存，lvgl有一个drm驱动直接可以使用drm显示。
