I need a help #9
Description
Hello @puckk ! Has anyone fixed the issue with CJMCU-3212? To flash it, I used this guide - https://github.com/puckk/CJMCU-3212. After shorting the contacts with a jumper and connecting it to my MacBook, the blue light stopped flashing. I then tried to flash it using the command 'esptool.py --trace --baud 115200 --port /dev/cu.usbmodem2101 write_flash 0x00000 /Users/apple/Projects/esp8266_wifi_duck_4mb.bin --flash_size 4MB --flash_mode dio --flash_freq 40m' and received this error.
