移植 DLNA 功能到小智 1.6.2 时，DLNA 导致设备重启 (AUD-6365)
Xiaozhi-ESP32 1.6.2 ESP-IDF 版本 5.4.1 ESP-ADF 版本 2.4 硬件 xingzhi-cube-1.54tft-wifi
直接编译例程 DLNA 没有问题。 将功能代码移植到小智（https://github.com/78/xiaozhi-esp32/）后，系统崩溃重启。由于 esp_media_protocols 没有开源，不方便进一步定位问题，请求帮助。

这个选项是开启的，我重新确认了下，并 clean 后重新编译了，问题依旧。 以下是编译配置： `#
GDB Stub
CONFIG_ESP_GDBSTUB_ENABLED=y
CONFIG_ESP_SYSTEM_GDBSTUB_RUNTIME is not set
CONFIG_ESP_GDBSTUB_SUPPORT_TASKS=y CONFIG_ESP_GDBSTUB_MAX_TASKS=32
end of GDB Stub`
是否和内存有关？有8MB PSRAM. `# SPI RAM config
CONFIG_SPIRAM_MODE_QUAD is not set
CONFIG_SPIRAM_MODE_OCT=y CONFIG_SPIRAM_TYPE_AUTO=y
CONFIG_SPIRAM_TYPE_ESPPSRAM64 is not set
CONFIG_SPIRAM_CLK_IO=30 CONFIG_SPIRAM_CS_IO=26
CONFIG_SPIRAM_XIP_FROM_PSRAM is not set
CONFIG_SPIRAM_FETCH_INSTRUCTIONS is not set
CONFIG_SPIRAM_RODATA is not set
CONFIG_SPIRAM_SPEED_80M=y
CONFIG_SPIRAM_SPEED_40M is not set
CONFIG_SPIRAM_SPEED=80
CONFIG_SPIRAM_ECC_ENABLE is not set
CONFIG_SPIRAM_BOOT_INIT=y
CONFIG_SPIRAM_IGNORE_NOTFOUND is not set
CONFIG_SPIRAM_USE_MEMMAP is not set
CONFIG_SPIRAM_USE_CAPS_ALLOC is not set

CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY is not set
CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY is not set
end of SPI RAM config
end of ESP PSRAM`
@jiangyanfeng 仍然建议打开 CONFIG_ESP_SYSTEM_PANIC_GDBSTUB，当系统异常 crash 时自动进入 GDB。
以下是常见指令，可输入 thread apply all backtrace 查看 log：
bt [-full] [n]：打印当前调试栈帧信息。若多线程，应执行 thread apply all backtrace f [args]：栈帧编号；栈帧地址；函数名 都可以作为参数 info registers：打印寄存器 info frame：查看栈帧中存储的信息 info args：查看当前函数各个参数值 info locals：查看函数中局部变量值 p/x [var]：打印变量 x/[n][f][u] [addr]：打印地址对应的值，n 是打印单元数，f 是打印格式，u 是单元长度。 q：退出 list：显示源程序内容
备注： 打印格式：x 十六进制；d 十进制；c 字符显示；f 浮点数显示； 单元长度：b 字节；h 半字；w 四字节；g 八字节
如果有复现工程，最好也可以提供复现工程。此外还可以使能 HEAP_ABORT_WHEN_ALLOCATION_FAILS 确认是否是内存申请失败导致的访问空结构体问题：https://docs.espressif.com/projects/esp-techpedia/zh_CN/latest/esp-friends/advanced-development/debugging/guru-meditation.html#load-access-fault-loadprohibited
