warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
- I am using this board from Amazon, nothing is connected besides the microUSB to the USB slot on my laptop: https://www.amazon.com/HiLetgo-Version- ... 010O1G1ES/
- Here are my settings
Board: NodeMCU 1.0 (ESP-12E module) - I also tried various other options
CPU Frequency 80 MHz
Flash Size: 4M (3M SPIFFS)
Upload Speed: 115200 (tried 9600)
- When I connect my serial monitor and press the reset button I see this:
<Garbage> n't use use rtc mem data
Ai-Thinker Technology Co.,Ltd.
ready
- I tried using ESP8266Flasher with no luck, it gets stuck unable to find my board
- I tried a ton of various MicroUSB cables with no luck, also tried connecting to PC instead of laptop (just in case) - but still getting same error
Any help is greatly appreciated - I pasted in detailed log below in case it helps:
