zynq中linux应用的远程调试配置

news 2026/6/30 6:13:39

Vitis +TCF

适合规模小,依赖轻的简单测试
Window -> Show View ->target Connections

Clion +GdbServer

适合规模大,依赖重的工程

windows 和 ubuntu 的clion都可以,但是windows的clion要用wsl里的交叉编译工具
程序直接放在 NFS 共享目录，编译后无需任何上传

开发板本地 GDB

将gdb编译进 Petalinux 根文件系统

PC上

# 进入petalinux工程petalinux-config-crootfs# 菜单路径Filesystem Packages → misc → gdb 勾选 gdb（板载完整本地调试器）、gdbserver（用于CLion远程调试）# 保存后重新编译根文件系统petalinux-build-crootfs# 重新打包系统镜像更新SD卡petalinux-package--boot...

开发板上

# 临时开启core转储，重启失效ulimit-cunlimited# 运行程序，段错误/崩溃自动生成core转储文件./hello# 用本地gdb加载core看崩溃位置gdb ./hello core.1234(gdb)bt

linux中PL寄存器读写脚本

PS通过AXI 转 SMMR,APB,AXI 等访问到PL
数据和地址统一32位
根据寄存器序号读写
