按照大佬的步骤，完整的实现了AWboot的编译过程，写了一个编译流程文档分享给大家参考。
AWboot需要用到arm-none-eabi-的交叉编译工具，我们首先进行环境配置:
# 1. 进入交叉编译器目录下
cd gcc-arm-none-eabi-10.3-2021.10-x86_64-linux/
# 2. 创建目录
sudo mkdir /usr/local/arm-none-eabi
# 3. 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/
# 4. 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，使用bash -c命令在文件/etc/profile末尾添加”PATH=$PATH:/usr/local/arm-none-eabi/bin”
sudo bash -c 'echo "export PATH=\$PATH:/usr/local/arm-none-eabi/bin" >> /etc/profile'
# 5. 添加完毕，使路径立即生效可以使用如下命令
source /etc/profile
# 6. 接下来在终端输入
arm-none-eabi-
# 8. 按两次tab键进行验证
#cd gcc-arm-none-eabi-10.3-2021.10/
#sudo mkdir /usr/local/arm-none-eabi
#sudo cp -rd * /usr/local/arm-none-eabi/
#sudo bash -c 'echo "export PATH=\$PATH:/usr/local/arm-none-eabi/bin" >> /etc/profile'
#source /etc/profile
#arm-none-eabi-
arm-none-eabi-addr2line arm-none-eabi-gdb
arm-none-eabi-ar arm-none-eabi-gdb-add-index
arm-none-eabi-as arm-none-eabi-gdb-add-index-py
arm-none-eabi-c++ arm-none-eabi-gdb-py
arm-none-eabi-c++filt arm-none-eabi-gprof
arm-none-eabi-cpp arm-none-eabi-ld
arm-none-eabi-elfedit arm-none-eabi-ld.bfd
arm-none-eabi-g++ arm-none-eabi-lto-dump
arm-none-eabi-gcc arm-none-eabi-nm
arm-none-eabi-gcc-10.3.1 arm-none-eabi-objcopy
arm-none-eabi-gcc-ar arm-none-eabi-objdump
arm-none-eabi-gcc-nm arm-none-eabi-ranlib
arm-none-eabi-gcc-ranlib arm-none-eabi-readelf
arm-none-eabi-gcov arm-none-eabi-size
arm-none-eabi-gcov-dump arm-none-eabi-strings
arm-none-eabi-gcov-tool arm-none-eabi-strip
## 1. 制作编译工具
cd awboot/tools/
gcc mksunxi.c -o mksunxi
# 2. 编译 awboot
cd ..
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. 烧录 bin文件到SD卡进行验证（若无串口打印信息请看下一章节）
sudo dd if=awboot-boot-sd.bin of=/dev/sdb bs=1024 seek=8
此处为在SD卡进行验证，若需要在其他介质上启动可以参考：
FEL memory boot:
xfel write 0x30000 awboot-fel.bin
xfel exec 0x30000
FEL SPI NOR boot:
make spi-boot.img
xfel spinor
xfel spinor write 0 spi-boot.img
xfel reset
FEL SPI NAND boot:
make spi-boot.img
xfel spi_nand
xfel spi_nand write 0 spi-boot.img
xfel reset
# 4. awboot支持MBR或者GPT分区，内核和设备树文件需要放置在一个偏移量至少为4M的FAT32分区，其中bin文件的偏移量：
MBR分区: 8KB (sector 16)
GPT分区: 128KB (sector 256)
拷贝zlmage文件和.dtb文件到FAT32分区
#cd ..
#cd awboot/tools/
#gcc mksunxi.c -o mksunxi
#cd ..
#make
#ls
Arch awboot-fel.bin build main.c
awboot-boot.bin awboot-fel.elf include main.h
awboot-boot.elf awboot-fel.map lib Makefile
awboot-boot.map board.c linux README.md
awboot-boot-sd.bin board.h linux-6.0-bootlog.txt tools
awboot-boot-spi.bin board-v851s.c linux-6.0-v851s.txt
#sudo dd if=awboot-boot-sd.bin of=/dev/sdb bs=1024 seek=81.打开awboot目录下的board.h文件
修改USART_DBG宏定义可以修改调试串口
#define USART_DBG usart3_dbg修改CONFIG_DTB_FILENAME宏定义可以修改设备树文件名
#define CONFIG_DTB_FILENAME "sun8i-t113-mangopi-dual.dtb"2.具体的串口定义可以在board.c文件中修改
打开awboot目录下的board.c文件，根据硬件进行配置，串口对应基地址和外设复用号可以查看本文档附录，也可以查看《T113-S3_User_Manual_V1.6.pdf》中的“GPIO Multiplex Function”章节。
sunxi_usart_t usart5_dbg = {
.base = 0x02501400,
.id = 5,
.gpio_tx = {GPIO_PIN(PORTB, 4), GPIO_PERIPH_MUX7},
.gpio_rx = {GPIO_PIN(PORTB, 5), GPIO_PERIPH_MUX7},
};
sunxi_usart_t usart0_dbg = {
.base = 0x02500000,
.id = 0,
.gpio_tx = {GPIO_PIN(PORTE, 2), GPIO_PERIPH_MUX7},
.gpio_rx = {GPIO_PIN(PORTE, 3), GPIO_PERIPH_MUX7},
};
sunxi_usart_t usart3_dbg = {
.base = 0x02500c00,
.id = 3,
.gpio_tx = {GPIO_PIN(PORTG, 8), GPIO_PERIPH_MUX5},
.gpio_rx = {GPIO_PIN(PORTG, 9), GPIO_PERIPH_MUX5},
};3.板载运行灯在board.c文件中led_blue变量定义处修改：
static gpio_t led_blue = GPIO_PIN(PORTD, 22);T113-S3串口号基地址和复用号表格（格式：Tx/Rx）此处省略，可以查看附件内容

awboot代码有点小问题，1，串口发送那边不能等busy标志，否则可能有概率死循环，2，华邦的2G SPINAND的6B命令，芯片手册上是发送4个字节，代码里是发送5个字节，改成4个字节就ok
