Recent always buy some cheap ESP8266 module (about TB 10 dollars) and brush to erase some found a problem when firmware

Erasure time

esptool.py --port /dev/ttyUSB0 erase_flash

Execution time is very short

The use esptool.py --port / dev / ttyUSB0 --baud 460800 write_flash --flash_size = detect 0 esp8266-20170108-v1.8.7.bin brush can not write

Brush writing time is short, finished can not start. . .

 

But these boards flashed at arduino is no problem that is as esptool dry, dio thought may be the cause, but also carefully looked at micropython explanation really is. .

 

For some boards with a particular FlashROM configuration (e.g. some variants of a NodeMCU board) you may need
to use the following command to deploy the firmware (note the -fm dio option):


esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dio  0 esp8266-20170108-v1.8.7.bin

----机翻：
对于某些具有特定FlashROM配置的电路板（例如NodeMCU电路板的某些变体），您可能需要
使用以下命令部署固件（请注意-fm dio选项）：
