ESP-IDF4.4.2 SPI驱动内存回收报错
Posted: Wed Oct 26, 2022 2:39 pm
模块：ESP32-S3 N8R2
环境：ESP-IDF4.4.2
我通过spi外接WK2124 SPI转串口芯片（SPI总线上只皆有此一个芯片），在内置串口与SPI外扩串口通讯时，每个串口分别在一个独立的任务中进行收发数据，每个串口也都启动了一个中断任务，程序启动第一次收发都正常运行，在第二轮收发时报错，错误信息如下：
如果把两个任务的串口对调，错误又稍有不同，错误信息如下：
我还发现一个奇怪现象，在调用SPI驱动接口前如加有printf或ESP_LOG来输出日志，则有可能正常运行（未长时间测试，未加日志输出则在第二次串口通讯时报错），这是什么原因呢？
