劳特巴赫ICD调试器CMM调用烧录框架固件研究之汇编版本

server/2024/9/23 2:21:38/

接到客户一个项目是基本GD32F301C8XX的，尝试用手上的劳特巴赫仿真器对它进行开发操作，发现总是提示“FLASH algorithm did not execute completely”

怀疑是底层调用用烧录固件“~~/demo/arm/flash/word/stm32f300.bin”与芯片不兼容造成的，于是有了这编研究文档，多的不说直接上代码吧，具体的操作，请自行查代码理解。另外发了一篇C语言版本的在付费专栏

劳特巴赫ICD调试器CMM调用烧录框架固件研究之C语言版本

以下是反汇编代码
