[bsp][cvitek] Milk-V Duo 256M Supports running ARM large core and RISCV small core
支持将rtthread.bin和dtb文件合成boot.sd文件，使用uboot直接通过bootcmd命令启动rtthread内核。 支持构建带有小核riscv程序的fip.bin文件，保证在运行arm大核的同时运行小核的riscv程序。

## 3. 运行

> 目前仅支持使用uboot对 `rtthread.bin` 文件进行加载，uboot对 `boot.sd` 的加载方式后续会实现。
|
||||
### 3.1 uboot加载rtthread.bin
|
||||
|
||||
1. 将 SD 卡分为 2 个分区，第 1 个分区用于存放 bin 文件，第 2 个分区用于作为数据存储分区，分区格式为 `FAT32`。

> 0x80200000为rtthread.bin加载到内存的位置，可在menuconfig中自己修改，注意不能与小核固件加载位置重叠。
|
||||
|
||||
### 3.2 uboot加载boot.sd
|
||||
|
||||
1. 将 SD 卡分为 2 个分区，第 1 个分区用于存放 bin 文件，第 2 个分区用于作为数据存储分区，分区格式为 `FAT32`。
|
||||
|
||||
2. 将bsp的boot目录下的 `fip.bin` 和编译生成的 `boot.sd` 复制 SD 卡第一个分区中。后续更新固件只需要复制 `boot.sd` 文件即可。
|
||||
|
||||
配置**串口0**参数： 115200 8N1 ，硬件和软件流控为关。
|
||||
|
||||
直接上电运行，uboot会自动调用bootcmd解析boot.sd文件，然后加载`rtthread.bin`运行。
|
||||
|
||||
### 3.3 如何生成fip.bin
|
||||
|
||||
在本bsp的boot/milkv-duo256m目录下存放了所有需要构建出fip.bin的一些依赖文件和相关脚本。用户只需要在boot目录下执行`combine.sh`即可生成fip.bin。
|
||||
|
||||
> 如何用户编译了小核c906_little的bsp，那么`combine.sh`脚本将会生成带有小核程序的fip.bin。未编译则不会。
|
||||
|
||||
完成后可以看到串口的输出信息：
