T113-S3主线Linux支持方案（基于TF卡,包含串口修改）

原贴在这里
https://bbs.aw-ol.com/topic/2338/mangopi-dual-t113-%E4%B8%BB%E7%BA%BF%E5%86%85%E6%A0%B8%E7%BC%96%E8%AF%91%E8%AE%B0%E5%BD%95
感谢Evlers大佬的付出。

需要注意的是：本篇是基于所用的引导的是AWboot 而非传统的uboot-spl方式，并且是该AWboot是专为T113-S3而构建的引导。

1 . 配置AWboot编译环境
   AWboot需要用到arm-none-eabi-的交叉编译工具，我这里使用到的是 gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
   下载地址：https://developer.arm.com/downloads/-/gnu-rm
   接下来配置编译环境
   

# 解压
tar -vxjf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2

# 创建目录
sudo mkdir /usr/local/arm-none-eabi

# 进入解压目录下
cd gcc-arm-none-eabi-10.3-2021.10-x86_64-linux/
# 将该目录下的所有文件复制到新建的目录下
sudo cp -rd * /usr/local/arm-none-eabi/


# 最后需要添加该工具链的环境变量使其可以在任何目录下执行，打开/etc/profile文件
sudo nano /etc/profile

# 在文件末尾添加以下内容
PATH=$PATH:/usr/local/arm-linux-gcc/bin

# 添加完毕，使路径立即生效可以使用如下命令
source /etc/profile

# 接下来在终端输入
 arm-none-eabi-
#按两次tab键进行验证

2 . 编译AWboot

# 下拉 awboot
git clone https://github.com/szemzoa/awboot
cd awboot

# 制作编译工具
cd tools
gcc mksunxi.c -o mksunxi


# 修改 Makefile 中的 /bin/expr 为 /usr/bin/expr
@/usr/bin/expr `/bin/cat .build_revision` + 1 > .build_revision
	
# 编译 awboot
make

如果文件夹下awboot下生成了：awboot-boot-sd.bin则表示工作正常了。

3 . 修改串口配置
  AWboot 默认使用UART5作为串口调试，但是因为墨云的板子使用的是UART3，所以需要进行一些调整，好在代码比较简单，进行如下修改：
  修改awboot目录下的board.cs文件，修改如图
  1.png
  需要注意base参数可以通过t113-s3用户手册查询到
  0x02500c00 为UART3 的地址
  还有就是对awboot/linux/sun8i-t113.dtsi、awboot/linux/sun8i-t113-snailpi-dual.dts 的修改
  主要是增加UART3 设备树配置和 BootArgs的配置，就是类似Uboot中BootArgs的配置：
  修改细微处较多，这里直接给文件吧

  awboot_sun8i-t113.zip
  awboot/linux/sun8i-t113.dtsi
  中pio节点下增加

	uart3_pb6_pins: uart3-pb6-pins {
				pins = "PB6", "PB7";
				function = "uart3";
			};

awboot/linux/sun8i-t113-snailpi-dual.dts
最后增加

&uart3 {
	pinctrl-0 = <&uart3_pb6_pins>;
	pinctrl-names = "default";
	status = "okay";
};

修改 aliases 

	aliases {
		//ethernet0 = &rtl8189f;
		mmc0 = &mmc0;
		serial1 = &uart1;
		serial3 = &uart3;
		//serial5 = &uart5;
	};

修改chosen (这个地方就是用来指定类似uboot中bootargs的地方)

        chosen {
		stdout-path = "serial3:115200n8";
/*
                bootargs = "mem=128M cma=72M root=/dev/mmcblk0p2 rw init=/sbin/init rootwait earlyprintk=sunxi-uart,0x02500c00 console=tty0 console=ttyS5,115200";
*/
                bootargs = "mem=128M cma=64M root=/dev/mmcblk0p2 rw init=/sbin/init rootwait console=tty0 console=ttyS3,115200 earlyprintk=sunxi-uart,0x02500c00";
        };

最后一个就是类似uboot指定zimage和设备树的地方
2.png
因为该项目是特定版本，所以只是单纯的指定名称，不用指定要写入内存的位置。

写入TF卡：

sudo dd if=awboot-boot-sd.bin of=/dev/sdb bs=1024 seek=8

最后是执行结果

本篇结束

内核部分可以先看前面的原贴，墨云稍后更新。

Re: T113-S3主线Linux支持方案（基于TF卡,包含串口修改）

内核编译
   可以直接找大佬修改好的主线稳定版内核(带WiFi)：Linux-6.0.1https://github.com/Evlers/linux_kernel_t113
   也选择去官网下载内核：kernel https://kernel.org/
   修改 kernel.org 下载的内核源代码（墨云直接使用的是大佬修改后的代码，所以这部分没验证） ：

# 修改 drivers/clk/sunxi-ng/Kconfig 文件
 config SUN20I_D1_CCU
 	tristate "Support for the Allwinner D1 CCU"
 	default RISCV && ARCH_SUNXI
-	depends on (RISCV && ARCH_SUNXI) || COMPILE_TEST
+	depends on (ARCH_SUNXI) || COMPILE_TEST
 
 config SUN20I_D1_R_CCU
 	tristate "Support for the Allwinner D1 PRCM CCU"
 	default RISCV && ARCH_SUNXI
-	depends on (RISCV && ARCH_SUNXI) || COMPILE_TEST
+	depends on (ARCH_SUNXI) || COMPILE_TEST

# 修改 drivers/clk/sunxi-ng/ccu-sun20i-d1.c 文件
 static SUNXI_CCU_MUX_DATA(cpux_clk, "cpux", cpux_parents,
-			  0x500, 24, 3, CLK_SET_RATE_PARENT);
+			  0x500, 24, 3, CLK_SET_RATE_PARENT | CLK_IS_CRITICAL);

# 修改 arch/arm/mach-sunxi/platsmp.c 文件，在末尾添加以下内容
static int sun8i_t113_smp_boot_secondary(unsigned int cpu,
				    struct task_struct *idle)
{
    u32 reg;
    void __iomem *cpucfg_membase = ioremap(0x09010000, 0x10);
    void __iomem *cpuexec_membase[] = {ioremap(0x070005C4, 0x10),ioremap(0x070005C8, 0x10)};

	if (cpu != 1)
	    return 0;

	spin_lock(&cpu_lock);

	/* Set CPU boot address */
	writel(__pa_symbol(secondary_startup),	cpuexec_membase[cpu]);

	/* Deassert the CPU core reset */
	reg = readl(cpucfg_membase);
	writel(reg | BIT(cpu), cpucfg_membase);

	spin_unlock(&cpu_lock);

	return 0;
}

static const struct smp_operations sun8i_t113_smp_ops __initconst = {
	.smp_boot_secondary	= sun8i_t113_smp_boot_secondary,
};
CPU_METHOD_OF_DECLARE(sun8i_t113_smp, "allwinner,sun8iw20p1", &sun8i_t113_smp_ops);

配置内核
  在内核根目录修改Makefile

  ARCH = arm 
  CROSS_COMPILE = arm-linux-gnueabihf-

配置默认编译规则

 make sunxi_defconfig

打开配置菜单

 make sunxi_defconfig menuconfig

打开芯片时钟支持：

> Device Drivers 
	> Common Clock Framework
		<*>   Clock support for Allwinner SoCs
			<*>     Support for the Allwinner D1 CCU 
			<*>     Support for the Allwinner D1 PRCM CCU

添加设备树
  将设备树添加到内核 arch/arm/boot/dts/ 目录中：sun8i-t113-snailpi-dual.dts sun8i-t113.dtsi (如果下载了大佬的Linux内核，就有这些文件,需要注意的是原版是 sun8i-t113-mangopi-dual.dts)
  linux-sun8i-t113.zip
  并在该目录 Makefile 文件中的CONFIG_MACH_SUN8I下添加改设备树文件：

dtb-$(CONFIG_MACH_SUN8I) += \
	sun8i-a23-evb.dtb \
	sun8i-a23-gt90h-v4.dtb \
	sun8i-a23-inet86dz.dtb \
	.....................
	sun8i-v3s-licheepi-zero-dock.dtb \
	sun8i-v40-bananapi-m2-berry.dtb \
	sun8i-t113-snailpi-dual.dtb

接下来就是正常编译

make

如果遇到

FATAL ERROR: MPC.H: 没有那个文件或目录

安装如下组件

sudo apt-get install libmpc-dev

接下来就是分区复制编译好的文件即可，这里不做赘述。
结合我们很久以前制作的Debian文件系统，那只熟悉的蜗牛又回来啦。

尝试调试WIFI，发现mmc1 初始化失败

dsp2000 说：

内核的编译也是使用gcc-arm-none-eabi-10.3-2021.10-x86_64-linux吗？好像是  CROSS_COMPILE = arm-linux-gnueabihf-
如果用arm-none-eabi有很多出错啊

内核用gnueabihf
