arduino和esp8266问题

Question

我似乎无法连接我的 esp8266 d1 mini；谁能帮我？

这是我收到的错误消息：

Arduino: 1.8.13 (Linux), Board: "LOLIN(WEMOS) D1 mini (clone), 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, DOUT (compatible), 40MHz, 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)

在处理上述异常的过程中，又出现了一个异常：
