ESP32 STATION 正接AP时候发生了PANIC然后重启了

[ttxs1002004]

“能否解析一下 crash 时候 backtrace？看一下 call stack。”，我感觉是BTC任务狗触发，既然高优先级的BTC都触发，那么IDLE0和IDLE1触发显然是必然的。问题是，为何没有什么操作的BTC WDT会触发？ 当时运行的BTC任务只是BLE广播状态而已。

此外，我的业务逻辑调用分区写备份数据，分区写/擦除会不会太占用时间，导致BTC有时没法及时工作（即使仅仅广播？）

1、你还是把发生 task WDT 和 crash 时的 backtrace 解析一下，可以获取一些 BTC task 内的情况，看为何 CPU0 都被这个 task 占用了，这个可能还需要内部蓝牙的同事看一下；
2、你现在 task WDT 的时间设置多大？能否设大一些做下测试？
3、不能确认是否和你的擦写有关，要做排除的话，能否暂时先把这部分做空操作；另外，建议在连不上网络时，不要频繁的做擦写操作，毕竟 flash 是有一定的寿命的。

多谢回复！！

“1、你还是把发生 task WDT 和 crash 时的 backtrace 解析一下，可以获取一些 BTC task 内的情况，看为何 CPU0 都被这个 task 占用了，这个可能还需要内部蓝牙的同事看一下；”

是的，需要你们蓝牙的专家看下，为何BTC控制器这个任务会触发WDT？尽管只是作广播？是不是这个BTC协议栈有测试不很充分？？

“2、你现在 task WDT 的时间设置多大？能否设大一些做下测试？”

默认的5秒WDT 超时，按照手册，IDLE有存储回收功能，如果设置太长会不会影响到API系统稳定？？我看IDF 源代码，大量使用动态存储分配释放。如果IDLE超时太长，会否出现没有及时释放回收动态存储器，导致耗尽内存?
我倒是想设置为30秒（最大60秒），但是实际上我的TASK不可能连续工作30秒，API内部任务会否需要连续30秒占用CPU?
我的TASK主循环要么用select(500毫秒左右），要么在主循环有vTaskDealy，最忙的主循环也有用vTaskDelay(5) 5毫秒的，而且我的任务最高优先级为10，我看源代码蓝牙的任务优先级是19，那么我的TASK本身是不会抢占到BTC，那么会不会是我调用的某些API抢占了CPU，导致BTC Task Watchdog Timeout .我固件中代码频繁调用的API有ADC、UART2读（不是基于事件）、WIFI的连接和断开，分区表API.


“3、不能确认是否和你的擦写有关，要做排除的话，能否暂时先把这部分做空操作；另外，建议在连不上网络时，不要频繁的做擦写操作，毕竟 flash 是有一定的寿命的。”

我是数据采集终端，2秒钟1K数据，连不上网就暂存在本地，暂存满了就循环覆盖，产品是这么设计的。
这个我会跟产品沟通下，也许不循环覆盖了。
我用的模块是8M FLASH版本的 ESP32-WROOM-32E，没有外部RAM的。

我看你第二次提供的 log 里有 [0;32mI (667) cpu_start: ESP-IDF: v4.2[0m，所以你当前使用的是 v4.2 的正式 release 版本？
针对 BTC task WDT 问题，我们在后继有相关修复，如你要验证，可拉取最新的 release/v4.3，在 commit b449909b 中有对此的修正；release/v4.2 上也有修正，但暂未同步到 github。

给你两个版本发布信息：
v4.2.1——计划在 4 月底 release
v4.3——计划在 5 月上旬 release

可在 github 留意一下 release 信息。

我实际用的应该是V4.3.
