请问ESP-AT是否支持openocd+jtag调试

[xsrlfc]

请问目前的esp-at工程是否支持通过指南中openocd+jtag的方法进行调试？

按指南中的方法尝试调试esp-at工程，openocd出现以下错误：

在网上搜索发现在新版本的FreeRTOS中似乎已经重新引入了uxTopUsedPriority，但是esp-at目前还是报错，请问现在支持通过这种方法调试吗？

[xsrlfc]

发现是esp-at项目的sdkconfig中缺少了CONFIG_ESP32_DEBUG_OCDAWARE=y这个设置，添加后重新编译工程可正常调试。

但是不知道为什么sdkconfig中少了这个配置

[ESP_Alson]

这个选项默认在 ESP-AT 中是不 enable, 如果要开启这个选项，可以在 menuconfig --> Component config --> ESP32-specific 中 enable Make exception and panic handlers JTAG/OCD aware 这个选项。
