Allwinner tina板级支持包

1. 简介

Allwinner tina 是由全志公司推出的ARM9内核的SOC 适用的开发板原理图见 burn/CherryPi-F1C200S.pdf

burn/boot.bin 来源自 https://gitee.com/LicheePiNano/lv7_rtthread_f1c100s?_from=gitee_search 需要源码自行下载编译即可,这个boot.bin 支持内存启动和norflash启动,由于spi 速率设置为100,也可能norflash 不支持 100M 启动会异常

我自己改造的boot 在 burn/f1c100s_spl_sd_nor_nand_uart1目录下,根据目标板,将boot log 输出到串口1,也可以修改成uart0, 屏蔽掉宏定义即可,我将spi 速度降为50M了,如果自己的nor flash 支持更改可以修改成100M, nand flash 驱动可以读取数据,但是卡在烧录这块 导致没启动成功,其他方式都可以启动成功

包括如下硬件特性:

硬件 描述
芯片型号 F1C100S
CPU ARM9
主频 408MHz
片内DDR 32MB
板载SPI Nand Flash 128MB

2. 编译说明

环境 说明
PC操作系统 Windows
编译器 arm-none-eabi-gcc version 6.3.1 20170620 (release)
构建工具 scons
  1. 下载源码
    git clone https://gitee.com/kasira/f1c200s_rtt_lvgl830.git
  1. 使用RT-Thread Studio 导入项目
    可以参考 https://whycan.com/t_9695.html 我写的说明 里面也包含 调试过程中遇得到的一些问题和解决方法
  1. 编译安装下载工具
   
  1. 编译项目
    工具栏选择 项目-》构建项目

如果编译正确无误,在Debug会产生rtthread.elf、rtthread.bin文件。其中rtthread.bin需要烧写到设备中进行运行。

3. 烧写及执行

1)下载并运行

1.连接USB
2.先按住开发板上的boot按钮再按下RST按钮
3.松开
4.双击burn目录下flashtoram.bat 烧录到内存运行,如果需要烧录到其他地方,可自行编译burn/f1c100s_spl_sd_nor_nand_uart1 下的 boot代码

D:\RT-ThreadStudio\workspace\iboard\burn>.\tools\sunxi-fel.exe spl boot.bin
D:\RT-ThreadStudio\workspace\iboard\burn>.\tools\sunxi-fel.exe -p write 0x80000
00 ..\Debug\rtthread.bin
100% [================================================]   440 kB,  309.2 kB/s
D:\RT-ThreadStudio\workspace\iboard\burn>.\tools\sunxi-fel.exe exec 0x80000000
请按任意键继续. . .

3.1 运行结果

如果编译 & 烧写无误,会在串口1上看到RT-Thread的启动logo信息:

如果您的开发板是CherryPi-F1C200S 直接使用开发板上的串口就行 i2c test CFG_VER GT911 verson 证明gt911 触摸OK last_x =533, last_y=368 触摸读出的坐标

boot.bin 说明及RTT改造

boot.bin 合法格式。

f1c100s 对 spi 引导程序是有格式要求的。格式细节我忽略不分析 start.S 内定义。

编译生成 boot.bin 之后用 mksunxi 对其进行校验,并填充相关位置。 让 f1c100s 能够认可 boot.bin ,并执行它。

burn/f1c100s_spl_sd_nor_nand_uart1 下的boot 在编译时会自动mksunxi 校验

boot.bin 逻辑

初始化 CPU 寄存器。 初始化中断状态。 设置中断向量表位置。 赋值中断向量表。 初始化时钟、DRAM、串口。 bl sys_clock_init bl sys_dram_init bl sys_uart_init 读取第二段程序并引导启动。 这里,第二段程序是 RTT。 如果是 uboot ,第二段就是 uboot 第二阶段。 bl sys_copyself 结束 有三种结束情况 1.返回spl 2.启动第二段程序 3.死循环 具体分析 sys_copyself 函数。 获取启动方式,如果不是SPI,那就返回 spl 状态(start.S 内定义)。 从 spi flash 0x00010000 读取 16 字节。

struct { 
    void (*Exe)(void); // 程序地址? 
    uint32_t magic; // 魔数 0xaa55aa55 
    uint32_t rev; // 没有使用。 
    uint32_t imgLength; // 程序大小。 
}head_t;
如果魔数不正确,将进入死循环 while(1)。
正确的情况下。
从 spi flash 0x00010000 读取 imgLength 长度数据到 0x80000000(DRAM);
然后直接跳转到 0x80000000。运行。

对应的第二阶段程序就有需要完成 head_t 头部信息。

RTT 需要修改内容:

start_gcc.S 文件 .vectors

最前面加入 head_t 结构。

b system_vectors ; 第二段程序向量表存放位置。

.long 0xaa55aa55 ; 魔数

.long 0 ; 留空

.long image_size ;

程序大小 image_size 让链接器进行计算即可,不需要另外使用工具进行处理。

修改 link.lds 文件 最前面位置加入

image_start = .;

.bss 段前面加入

__ image_end = .;

最末尾处计算一下

__ image_size PROVIDE(image_size = image_end - image_start);
