Eclipse 调试-GNU ARM裸机开发

我正在调试Atmel给出的示例代码。我已经成功地建立了这个程序

为了调试，我正在使用

eclipse

plus

gdb

plus

JlinkGDBServer

plus板载Jtag

虽然程序可以下载到主板上并且运行良好，但我无法调试程序。每次启动调试会话时，JLinkGDBServer将终止，并出现错误，如下所示：

target remote localhost:2331
monitor reset
load
mon reg pc = 0x300000
mon reg pc = 0x300000
end

以下是控制台中显示的每个程序终止的消息：

以下是我的调试配置：

在“运行命令”下，框中的命令如下所示：

target remote localhost:2331
monitor reset
load
mon reg pc = 0x300000
mon reg pc = 0x300000
end

我不知道根本原因是什么。我怀疑是

arm none eabi gdb

导致

JLinkGDBServer

终止，退出代码为

-1

请帮忙

仅供参考，我使用的是SAMA5D3x EK开发板。

很难说，但看起来处理器在加载代码时出现异常。我建议验证ELF文件各节的加载地址，并查看项目的链接器设置

希望对您有所帮助……

您解决了这个问题吗，我有一个类似的问题……不幸的是，我还没有解决这个问题。目前，我正在使用IAR编译器在windows环境下进行开发。工作示例设置：
