在RT-thread下使用HASH hwcrypto配置底层硬件HAH库过程记录

1，使用hwcrypto 需要使用env 工具配置该选项，这里使用的是SHA1

2，scons --target=mdk5后可以看到驱动已经配置，但是要想使用，对于STM32f4,还需要在cubemx里面打开添加编译选项

然后重新生成代码。可以看到相应代码已经生成

3，还需在boardKconfig文件中添加编译选项
config BSP_USING_HASH
      bool "Enable use hash arithmetic"
      select BSP_USING_HASH
      default n
4，然后发现相关定义还是无法加载进来，需要做如下配置
首先，需要在stm32f4xx_hal_conf.h文件中打开编译选项
#define HAL_HASH_MODULE_ENABLED
然后librariesSTM32F4xx_HALSConscript文件，加入如下内容
import rtconfig
from building import *
# get current directory
cwd = GetCurrentDir()
# The set of source files associated with this SConscript file.
src = Split('''
CMSIS/Device/ST/STM32F4xx/Source/Templates/system_stm32f4xx.c
STM32F4xx_HAL_Driver/Src/stm32f4xx_hal.c

''')
... ...
path = [cwd + '/STM32F4xx_HAL_Driver/Inc',
cwd + '/CMSIS/Device/ST/STM32F4xx/Include',
cwd + '/CMSIS/Include']
CPPDEFINES = ['USE_HAL_DRIVER','HASH']
group = DefineGroup('Libraries', src, depend = [''], CPPPATH = path, CPPDEFINES = CPPDEFINES)
Return('group')
4,完成修改后，重新scons --target=mdk5，这时会在MDK环境的Options for ...C++选项卡里多出了一项HASH定义
