1.1 Eclipse
本文中使用的Eclipse为芯来的 NucleiStudio_IDE_202212关于Eclipse安装方式不在此累述。 下载地址https://www.nucleisys.com/download.php
1.2 工程编译 对于一个全新的测试的话需要编译一个全新的文件系统rootfs在编译文件系统时已经默认编译了 OpenSBI、U-Boot、Kernel、OpenSSL、CCAT-Engine、CCAT等但是为了更好的了解使用这些工程也可以独自编译它们。 下面采用 yocto 的方式编译文件系统等。
编译文件系统rootfs 注在编译文件系统之前必须首先修改U-Boot 及 Kernel 的配置项参考章节 “编译U-Boot” 及 “编译Kernel” 中的说明 roott690mp-evb2-va: MACHINEt690mp-evb2-va bitbake tih-full-cli-debug-image -c cleanall

2. 创建工程
2.1 搭建调试工程 创建并导入待调试的工程的目的是方便跟踪、查看、并修改源码切记这里导入的是源码工作的链接文件而不是源文件 点击File/New/Project 导入工程ccat、ccat_engine、openssl 依次导入CCAT、CCAT_Engine、OpenSSL的源码工程链接。
2.2 配置Dbug调试信息 在“debug工程”右键选择“Debug As \ Debug Configurations”,进入如下配置界面。按照下面图示进行配置
配置可执行程序testapp的路径
/* 当前测试case的可执行程序路径如下 */
/localhdd/jack/tmp-glibc/work/riscv64-tih-linux/ccat-engine/1.0-r0/ccat-engine-1.0/testapp配置GDB及GDB调试信息 备注此处配置的工具链必须与开发板上的工具链保持一致建议直接使用我们导出的工具链 工具链的位置/localhdd/jack/tih_toolchain/sysroots/x86_64-tih_sdk-linux/usr/bin/riscv64-tih-linux/riscv64-tih-linux-gdb ccat.gdbinit记录了GDB的命令启动GDB时会解析该命令该文件的内容如下
/* 设置共享库的搜索路径 */
set solib-absolute-prefix /share/samba/public/shared/jack/rootfs_gmssl//* 设置ccat源码的替换搜索路径 */
set substitute-path /usr/src/debug/ccat/1.0-r0/ccat/ /localhdd/jack/tmp-glibc/work/t690mp_evb2_va-tih-linux/ccat/1.0-r0/ccat//* 设置ccat-engine源码的替换搜索路径 */

set substitute-path /usr/src/debug/openssl/1.1.1q-r0/openssl-1.1.1q/ /localhdd/jack/tmp-glibc/work/riscv64-tih-linux/openssl/1.1.1q-r0/git/设置共享库的搜索路径 设置IP及端口号

4. 手动调试过程 章节3中介绍了怎么使用Eclipse调试的方式也可以使用纯手动的方式进行调试这里也记录一下这种调试过程假设板子都已经正常运行此处仅描述 gdb 的过程。
在串口终端执行gdbsever命令 gdbserver 192.168.100.49:1234 testapp -engine ccatengine -v sm2 服务器端开启一个新的终端执行命令/localhdd/jack/tih_toolchain/sysroots/x86_64-tih_sdk-linux/usr/bin/riscv64-tih-linux/riscv64-tih-linux-gdb /localhdd/jack/tmp-glibc/work/riscv64-tih-linux/ccat-engine/1.0-r0/ccat-engine-1.0/testapp输入命令target remote 192.168.100.49:1234修改查询共享库的路径set solib-absolute-prefix /share/samba/public/shared/jack/rootfs_gmssl/设置CCAT源码的路径set substitute-path /usr/src/debug/ccat/1.0-r0/ccat/ /localhdd/jack/tmp-glibc/work/t690mp_evb2_va-tih-linux/ccat/1.0-r0/ccat/设置Engine源码的路径set substitute-path /usr/src/debug/ccat-engine/1.0-r0/ccat-engine-1.0/ /home/jack/svn_project/t690/sdk/trunk/linux/pkg/tih/lib/ccat_engine/设置GMSSL源码的路径 set substitute-path /usr/src/debug/openssl/1.1.1q-r0/openssl-1.1.1q/ /localhdd/jack/tmp-glibc/work/riscv64-tih-linux/openssl/1.1.1q-r0/git/设置断点 b main后面就可以使用gdb的命令进行愉快的调试了。整过过程执行代码如下所示

jackfw02:~$ 4. 总结
gdb与gdbserver必须使用同一个版本的。在使用Eclipse进行调试时当配置文件中指定了共享库的搜索路径之后在ccat.gdbinit中可以不再指定共享库的搜索路径了。但是若在该文件中指定共享库的搜索路径则启动调试到调试环境就绪所消耗的时间要比在配置选项中指定共享库所消耗的时间少的多。
