我正在尝试调试 Atmel 给出的示例代码。我已经成功构建了程序。
对于调试，我使用eclipseplus gdbplus JlinkGDBServerplus 板载 Jtag。
虽然程序可以下载到板上并且运行良好，但我无法调试程序。每次我启动调试会话时，JLinkGDBServer都会因以下错误而终止：
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：
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。我怀疑这是arm-none-eabi-gdb导致JLinkGDBServer以退出代码终止的原因-1。
请帮忙。
