首创为CW32L083创建GCC开发工程模版
<p>【目的】</p><p> </p>
<div >官方示例提供了MDK、IAR的示例，也提供了以上两个环境的工程模板，但是没有GCC的工程模板，GCC编译环境与MDK、IAR主要区别就是C语言启动环境的配置、链接文件的不一至，因为要实现VScode或者其他的编译器来实现开发环境的搭建，就需要自己编写CW32L083_FLASH.ld、以及startup_cw32l083_gcc.s。</div>
<div >【实现的思路】</div>
<div >1、寻找官方支持，我在CW32生态群里发了求助的信息，没有回复。</div>
<div >2、在淘宝客服，咨询，回复说，没有工程。</div>
<div >3、有大佬提供了CW32F030的工程，我了解到CW32F030与CW32L083一样是CortexM0+的内核，所以想他的启动文件跟LD应该可以相互借鉴。所以偿试修改CW32F030的工程来实现GCC的工程。</div>
<div >【实现步骤】</div>
<div >1、拷贝一份工程，另存为cw32l083_gcc，并用vscode打开。</div>
<div >2、到官网下载cw32l083的固件库。</div>
<div >3、把cw32l083-stdperiph-lib/Libraries下面的固件替换掉cw32l083_gcc/Libraries固件。</div>
<div >4、复制cw32l083.h、system_cw32l083.h到/Libraries/CMSIS/Device/目录下面。删除原来的cw32f030.h以及system_cwl083.h。</div>
<div >5、Libraries/CMSIS/Device/startup_cw32f030_gcc.s重命名为startup_cw32l083_gcc.s。</div>
<div >6、Libraries/CMSIS/Device/CW32f030_FLASH.ld重命名为CW32L083_FLASH.ld。</div>
<div >7、Debug/CW32F030.svd 重命名为CW32L083.svd。并把其文件内的cwf030修改为cw32l083.</div>
<div >8、复制l083固件库中的cw32l083-stdperiph-lib/IdeSupport/MDKWHXY.CW32L083_DFP.1.0.8.pack 到Debug/WHXY.CW32L083_DFP.1.0.8.pack，并删除原来的.pack文件。</div>
<div >9、复制cw32l083-stdperiph-lib/Examples/GPIO/gpio_blink/USER/src/interrupts_cw32l083.c 到/cw32l083_gcc/Core/app/interrupts_cw32l083.c。以及inc下面的interrupts_cw32l083.h。</div>
<div >10、修改Libraries/Libraries.mk文件内容，主要是文件夹的名称重新定位。</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word"># 模块名_DIR 是上一层传递下来的参数，<br style=" overflow-wrap:break-word" />
# 是从工程根目录到该模块文件夹的路径<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
# 向 C_SOURCES 中添加需要编译的源文件<br style=" overflow-wrap:break-word" />
C_SOURCES += $(wildcard $(Libraries_DIR)/CW32L083_StdLib/src/*.c)<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
# 向 C_INCLUDES 中添加头文件路径<br style=" overflow-wrap:break-word" />
C_INCLUDES += -I$(Libraries_DIR)/CMSIS/Include<br style=" overflow-wrap:break-word" />
C_INCLUDES += -I$(Libraries_DIR)/CMSIS/Device/<br style=" overflow-wrap:break-word" />
C_INCLUDES += -I$(Libraries_DIR)/CW32L083_StdLib/inc<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
# 向 LIBDIR 中添加静态库文件路径<br style=" overflow-wrap:break-word" />
# LIBDIR += -L$(Libraries_DIR)/Lib<br style=" overflow-wrap:break-word" />
# 向 LIBS 中添加需要链接的静态库<br style=" overflow-wrap:break-word" />
# LIBS += -lxxxx<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />

LDSCRIPT = $(Libraries_DIR)/CMSIS/Device/CW32L083_FLASH.ld<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
<br style=" overflow-wrap:break-word" />
# 汇编文件宏定义<br style=" overflow-wrap:break-word" />

<br style=" overflow-wrap:break-word" />

<br style=" overflow-wrap:break-word" />
# 汇编源文件（starup）<br style=" overflow-wrap:break-word" />
ASM_SOURCES += $(Libraries_DIR)/CMSIS/Device/startup_cw32l083_gcc.s<br style=" overflow-wrap:break-word" />

</div>
11、修改makefile，修加gcc的路径：</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word">#######################################<br style=" overflow-wrap:break-word" />
# 编译器指定<br style=" overflow-wrap:break-word" />
#######################################<br style=" overflow-wrap:break-word" />
PREFIX = arm-none-eabi-<br style=" overflow-wrap:break-word" />
# 启用下一项以指定GCC目录<br style=" overflow-wrap:break-word" />
GCC_PATH = /Applications/ARM/bin/</blockquote>
</div>
12、修改pyocd.yaml，指定tartgets、pack包名称：</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word">pack: ./Debug/WHXY.CW32L083_DFP.1.0.8.pack<br style=" overflow-wrap:break-word" />
target_override: CW32L083vc<br style=" overflow-wrap:break-word" />
frequency: 24000000</blockquote>
</div>
13、查找CW32L083用户手册，修改/Libraries/CMSIS/Device/CW32L083_FLASH.ld的RAM、FLASH如下：</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word">/* Specify the memory areas */<br style=" overflow-wrap:break-word" />
MEMORY<br style=" overflow-wrap:break-word" />
{<br style=" overflow-wrap:break-word" />
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 24K<br style=" overflow-wrap:break-word" />
FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 256K<br style=" overflow-wrap:break-word" />
}</blockquote>
</div>
14、由于.h与MDK的编译上有所差别会报警告</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word">Libraries/CW32L083_StdLib/inc/cw32l083_gtim.h:272:52: warning: suggest parentheses around comparison in operand of '&' [-Wparentheses]<br style=" overflow-wrap:break-word" />
272 | #define IS_GTIM_DMA(DMA) (((DMA) & 0xFFFFFFC0 == 0x0UL) && (DMA) != 0x0UL)</blockquote>
</div>
修改为：#define IS_GTIM_DMA(DMA) ((((DMA) & 0xFFFFFFC0) == 0x0UL) && (DMA) != 0x0UL)，消除运算符的警告。</div>
<div >15、修改SysTick.c中的__weak 编译错误，修改为：__attribute__ ((weak))</div>
<div >到此，工程修改就结束。</div>
<div >编译后无警告无错误：</div>
<div >
<div style="border:1px solid #cccccc">
<blockquote style=" overflow-wrap:break-word"> build_exec/template.elf<br style=" overflow-wrap:break-word" />
