coredump怎么使用？

环境：window11 vscode
版本库：v5.0-rc1*

我按ESP--FAQ文档来使用coredump
https://docs.espressif.com/projects/esp ... 2-coredump
在执行espcoredump.py info_corefile -t elf -c coredump.bin C:\Users\15119\esp\Code008_ESPS32\build\Code008.elf时.
出现了以下问题：

查阅了网上的其他案例，有的说是4.3之后就会出现这个问题。
请问这个问题要如果解决？谢谢

IDF monitor 带有 自动解码地址 的功能，您可以直接参考 https://docs.espressif.com/projects/esp ... r.html#id3。 从而无需自动解码。

此外，观察到您的 IDF 版本不是一个正式的 tag 分支，您是否方便切换到类似于 ESP-IDF 5.0.2 或者 ESP-IDF 5.1 上再做手动解析 coredump 的尝试？可以参考 https://docs.espressif.com/projects/esp ... _dump.html

您好，我切换到了ESP-IDF 5.1，参考了这里的文档https://docs.espressif.com/projects/esp ... _dump.html。
但在执行以下命令后，仍然显示有错误，如下：

您好，您可以直接使用 idf.py coredump-info 来获取对应信息，比如：
