gdb调试

记录使用vscode图形化调试嵌入式设备上c++程序的过程,例如orin.

由于嵌入式设备未直接接入网络,因此调试还经过了跳板机.

嵌入式设备

准备好包含debug信息的可执行程序,使用gdbserver开启调试.

cuda-gdbserver :1234 test 1 2 3

attach

attach需要额外配置打开权限

# 临时配置
sudo sh -c "echo 0 >/proc/sys/kernel/yama/ptrace_scope"
# 永久配置
sudo sh -c "echo "kernel.yama.ptrace_scope = 0" >> /etc/sysctl.conf"

client

ssh config

以下配置实现了以下效果:

ssh orin1__1可以跳过orin1,直接连接到orin,同时将client的1234端口映射为orin的1234端口 ```sh ServerAliveInterval 20 TCPKeepAlive no StrictHostKeyChecking no NoHostAuthenticationForLocalhost yes RequestTTY yes Host *__1 HostName 172.16.45.98 LocalForward 1234 172.16.45.98:1234 Host *__2 HostName 172.16.45.100 Host *__1 *__2 User nvidia Port 22 UserKnownHostsFile /dev/null LogLevel ERROR
