LV.1 #12 lly回复#9zhangyanting回复您好，生成的-o文件需要进行再编译，以得到可调式程序，您可以参考：CNGDB 安装 — 寒武纪CNGDB用户手册 v1.14.0 文档 (cambricon.com)

展开你好，我按照上面的示例，可以编译，使用cngdb还是不行

[图片]mat.zip 代码编译命令`cncc matrixmul.mlu -o mat -g -O0 --bang-mlu-arch=MLU270`进行调试命令为`cngdb ./mat`进入cngdb后执行`b main`,`r`,`cngdb breakpoints on`,`b 47`,`r`程序直接结束，没有在设备端代码的47停留

您好，mat.zip中的文件内容为空，请您检查下上传文件中内容的完整性。
抱歉，我重新传了下。这个就是安装包samples`/samples/BANG/bang-c/matrixmul`中matrixmul.mlu文件
