Unable to upload using Arduino or esptool.py

Redcof opened this issue · comments

I am trying to flash a program into Amica NodeMCU ESP8266. I have tried in Window 10 and OSX.
I have tried

  1. plain esptool.py command line in OSX 10.13.4 High Sierra
  • esptool.py --port /dev/tty.SLAB_USBtoUART --baud 115200 --before "default_reset" --after "hard_reset" write_flash --flash_mode "dio" --flash_freq "80m" --flash_size 4MB 0x1000 /Users/soumensardar/Downloads/sketch_jul13a.ino.bin
  • esptool.py --port /dev/tty.SLAB_USBtoUART write_flash 0x1000 /Users/soumensardar/Downloads/sketch_jul13a.ino.bin
    By holding down the FLASH button when plugin the USB to mac and/not clicking RST, I have issued the commands in terminal.
    Output:

and it keeps on waiting here

  1. NodeMCU Flasher Windows 10
    I do not have the exact error right now. But the lower left corner got red and the log says kind of timeout

I am using 1 meter USB cable provided by my smartphone manufacturer.
I have installed the CP2102 driver

Is there any problem with my NodeMCU module or I am missing any point?
