在芒果派麻雀全志D1s上运行国产开源rt-smart系统

想必RT-Thread系统大家不陌生了，RT-Thread Smart（简称 rt-smart）是基于 RT-Thread 操作系统衍生的新分支，面向带 MMU，中高端应用的芯片，例如 ARM Cortex-A 系列芯片，MIPS 芯片，带 MMU 的 RISC-V 芯片等。rt-smart 在 RT-Thread 操作系统的基础上启用独立、完整的进程方式，同时以混合微内核模式执行。
官方文档：https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-smart/rt-smart-quickstart/rt-smart-quickstart

内核：rt_smart_kernel.bin

硬件：麻雀，MQ1或MQ1W

RT-smart包（自带编译器）：mango_rtsmart_app.zip

1. 分区

使用fdisk分区。
将u盘挂载到ubuntu系统后，笔者设备路径是/dev/sdb。使用的32GB TF卡，扇区大小512字节，根据说明预留8M的空闲，那么计算得知分区扇区开始于：16384
命令：sudo fdisk /dev/sdb
选：o,n,p,1,16384,回车

Command (m for help): o
Created a new DOS disklabel with disk identifier 0x3668b987.

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-62410751, default 2048): 16384
Last sector, +sectors or +size{K,M,G,T,P} (16384-62410751, default 62410751): 

Created a new partition 1 of type 'Linux' and of size 29.8 GiB.

Command (m for help): w
The partition table has been altered.

正确的分区效果如下：

mango@virtual:/dev$ sudo fdisk -l /dev/sdb
Disk /dev/sdb: 29.8 GiB, 31954305024 bytes, 62410752 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x3668b987

Device     Boot Start      End  Sectors  Size Id Type
/dev/sdb1       16384 62410751 62394368 29.8G 83 Linux
mango@virtual:/dev$ 

然后格式化sdb1：

$ sudo mkfs -t fat /dev/sdb1

2. 刷入RT-SMART内核

$ sudo dd if=rt_smart_kernel.bin of=/dev/sdb bs=1024
2888+1 records in
2888+1 records out
2957313 bytes (3.0 MB, 2.8 MiB) copied, 8.32574 s, 355 kB/s
$ sync

3. 启动RTT

此时将TF卡放入麻雀，串口0（底部排针的7，8脚），串口波特率500000，然后上电：

4. 运行应用程序

祭出祖传hello程序：根据说明自行编译，输出为：hello.elf 文件，直接
拷贝到TF卡的文件系统中

然后重新将tf卡放进麻雀，开机启动：

msh />ls
Directory /:
System Volume Information<DIR>
etc                 <DIR>
hello.elf           237512
vi.elf              398544
msh />
msh />./hello.elf
msh />hello world!

至此，hello程序就运行起来了！

5. 扩展之编译

• 请在Linux下使用此开发环境包（已经自带64位Linux系统的编译器环境），如果要在Windows下使用，请自行配置安装编译在tools目录下，然后参照smart-env.sh里的脚本配置好环境变量。
• 在Linux下使用步骤：
  • 首先执行source smart-env.sh riscv64，也可以根据自己的环境稍作修改。
  • 进入userapp目录进行应用编译，例如编译自带的hello应用程序，只需要执行scons --app=hello。
  • 编译好的应用程序会生成在root/bin目录下，将其拷贝到SD卡中（注意是8M偏移的起始分区），然后进入rt-smart系统中，启动挂载成功后即可运行。
