基础库移植
首先移植一下基础结构，按照SDK的结构编辑修改。把头文件放置于include/tinymaix 文件夹里
源文件放置于 src/tinymaix 文件夹里
编辑 Makefile 增加引索
#
# Rules for building library
#
# ----------------------------------------------------------------------------
# common rules
# ----------------------------------------------------------------------------
ROOT_PATH := ../..
include $(ROOT_PATH)/gcc.mk
# ----------------------------------------------------------------------------
# library and objects
# ----------------------------------------------------------------------------
LIBS := libtinymaix.a
DIRS := .
SRCS := $(sort $(basename $(foreach dir,$(DIRS),$(wildcard $(dir)/*.[csS]))))
OBJS := $(addsuffix .o,$(SRCS))
CC_FLAGS += -Wno-unused-variable -Wno-error=unused-but-set-variable -Wno-error=multichar -Wno-unused-but-set-variable -Wno-multichar
# library make rules
include $(LIB_MAKE_RULES)
在 project/Kconfig 里增加 Kconfig 引索
# Sipeed lib TinyMaix
config TINYMAIX
bool "TinyMaix is a tiny inference library for microcontrollers (TinyML)."
default n
help
set y to build library tinymaix.
同样吧project/project.mk加入引索
mnist demo 移植
先复制一份hello_world，重命名为 tinymaix_mnist
在 defconfig 里加入使用的包
运行错误，exception:6 happen!!
烧录板子上运行之后发现不能正常使用，报错如下：

参考Arm® Cortex®-M33 Devices Generic User Guide，查阅到 exception:6 为 usage fault
继续追踪，查看 UFSR 寄存器定义，结合上面报错 usage fault happen, UFSR:0x100 可以得出这里的错误是 UNALIGNED ，也就是 Illegal unaligned load or store
对于 Cortex M33 平台，仅仅支持如下的部分访问方式，其他的访问方法均会触发UNALIGNED错误
那么看一下是哪一行代码触发了这个错误，看最后一个PC指向的地址：0x00204062
位于 tm_stat.c，看上去只是一行普普通通的 printf ，注释了看看效果。
虽然也出错了，但是代码已经运行到后面去了，现在继续上面的操作。

找到 PC->0x0020420e 果然又是printf
注释掉
然后终于不是死在printf 上了，死在 switch 上了
这就没招了，询问群里大佬
那行，换一个编译器看看，换一个 gcc-arm-none-eabi-10.3-2021.07-x86_64-linux.tar.bz2，测试完全正常。
Kconfig 增加选项
每一次修改模型类型，优化都要修改头文件，太不优雅了，加入 Kconfig 里直接配置比较好
