我正在调试 NodeMCU Lua 固件的 dev-esp32 分支上的一些崩溃。你们其他 NodeMCU 开发人员如何分析回溯？
在正常的 ESP32 开发期间，idf 监视器处理解码回溯。我尝试在我的 NodeMCU 构建中使用 IDF 监视器（不成功）。我也试过https://github.com/me-no-dev/EspExceptionDecoder没有成功。
在我深入研究这个问题之前，我想我会检查其他人是如何处理它的。
下面是我尝试解码的输出类型的一个示例。

有关解码器尝试的附加信息
对于 EspExceptionDecoder 尝试，我将崩溃输出保存在一个名为backtrace. 然后我按如下方式调用解码器，这会导致解析器错误（确认路径正确）。

我在上面尝试的backtrace文件具有以下内容（注意 sha 与上面的检查相匹配）。
