안녕하세요~

예전에 구입한 WeMos D1 R1 보드로 지금까지 잘 사용해 왔는데요.

최근에 다른 센서로 새 코드를 작성하다보니 첨부한 오류 메시지가 뜨면서 업로드 자체가 되질 않더군요.

아두이노:1.8.8 (Windows 10), 보드:"WeMos D1 R1, 80 MHz, Flash, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 9600"

Uploading 250224 bytes from C:\Users\moon\AppData\Local\Temp\arduino_build_413542/sketch_dec25a.ino.bin to flash at 0x00000000

warning: espcomm_send_command: didn't receive command response

warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed

error: espcomm_upload_mem failed

error: espcomm_upload_mem failed

그래서 기존 코드를 다시 업로드 시도해 봤으나 역시 같은 메시지가 출력됩니다.

혹시나 싶어 ESP8266 Blink 예제를 돌려봐도, 첨부한 스크린샷과 같이 빈 코드만 둬도 계속 같은 오류 메시지가 나오네요.

또 드라이버 문제인가 싶어 다른 컴에서도 업로드 해 봤지만, 역시나 같은 메시지가...

물론 컴파일은 정상적으로 됩니다.

드라이버 버전도 2.3.0에서 2.5.0 베타버전,

보드도 WeMos D1 R2 mini, Wemos D1 R1 등 확인해 봤으나 해결되지 않네요.

어떤 조치가 필요한지 도움 부탁드립니다.
