用两个8285实现了一个点到点的SPI到TCP的透传,因为速率的原因,SPI方面开了一个很大的缓冲区(28Kbyte)。故障现像表现为:在很大的数据流量时(300Kbyte/s 以上),传输会突然中止而无法恢复,只能通过复位恢复。同时出问题的永远都是软AP,TCP服务器端的8285.
速度越快,死得越快,但也不一定,有时就不会有问题,但速率高了以后通常有个20秒左右就会出现。
初步怀疑内存分配的问题,不知道SDK内部有多少是动态分配的情况?
目前问题已解决,问题出在我处理缓冲区时的数据判据不严瑾,造成数据缓存失效。
ESP8285 NO OS SDK TCP服务器在大数据量情况下可能造成响应停止
