我正在尝试使用 GDB 调试使用 OpenOCD 和 GNU ARM 工具链(随 MacPorts 一起安装)的 Stellaris LM3S8962 评估板，每当我在 GDB 中设置远程目标时，它总是返回“对偏移查询的 Malfomred 响应，qOffsets”。关于可能出什么问题的任何想法？有什么我想念的吗？

我能够使用工具链进行编译，并使用 OpenOCD 刷新生成的 .bin 文件。我一直无法通过搜索网络找到“格式错误的响应”问题的解决方案。
在此先感谢您的任何建议或帮助!
更新
感谢@turbo-j 和@guy-sirton 的回答，我能够更进一步......迄今为止最有帮助的是我确实使用了错误的端口(4444 而不是 3333)，但现在我得到了以下是否将
-c "init" -c "halt" -c "reset halt" 添加到我的 openocd 命令字符串中:(gdb) target remote localhost:3333
Remote debugging using localhost:3333
Remote 'g' packet reply is too long: 0080004000000000040000220f0000002833405451332abc009600a4d2b86092c0c118c03040d6f0284dbb93204b40c2000000000c010020ffffffff550400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000020000001
(这是在 qOffsets req/resp 之后，现在通过)
在 OpenOCD 方面:
Info : accepting 'gdb' connection from 3333
Warn : acknowledgment received, but no packet pending
Info : dropped 'gdb' connection
有时在 OpenOCD 控制台上有一个
undefined debug reason 6 - target needs reset ......不确定现在发生了什么，但它似乎更接近运行更新 2
似乎如果我不加载文件 'main.axf' 或 'main.o' 我不会遇到
Remote 'g' packet reply is too long 但我没有得到任何符号...我注意到其他网站主要处理 .elf 扩展名。有什么区别？我正在使用 StellarisWare 的“Hello World”示例，它从 make 命令生成 main.axf、main.bin(闪存写入并运行良好)、main.d、main.o。我的 Makefile 有什么奇怪的地方？ 最佳答案
这是一个类似于@athquad 提到的补丁。有关更多信息，请参阅他的回答。感谢他有效地将我指向正确的位置，对于提供补丁而不提供它确实感到非常遗憾。 :-P
