Hello, you possible use an old flashtool, please update.

   https://github.com/themadinventor/esptool
2. Please use latest NodeMCU flasher with default option (must click 'restore to default' in advanced tab)
   https://github.com/nodemcu/nodemcu-flasher
3. Please use latest Espressif's flash tool(without auto download support)
   If always have problem, please use latest flash download tool from espressif. http://bbs.espressif.com/viewtopic.php?f=5&t=433 Please use DIO mode and 32M flash size option, and flash latest firmware to 0x00000. Before flashing firmware, please hold FLASH button, and press RST button once. When our firmware download tool released, it will flash firmware automatically and needn't press any button.

Hi,

I have been using esptool.py downloaded from the master branch (e96336f6561109e67afe03c0695d1e5b0de15da6) and it did not work.

Here is the commandline I am using:

./esptool.py --port /dev/ttyUSB0 write_flash 0x00000 <firmware> -fs 32m -fm dio -ff 40m

I am using the Amica black board on Linux.

I have the same problem with @rjpcomputing , also using the Amica black board.
I tried all the methods. Only the tool on http://bbs.espressif.com/viewtopic.php?f=5&t=433 work fine.
But I need esptool.py on Linux

from nodemcu-devkit-v1.0.

@Air000 how to use esptool from http://bbs.espressif.com/viewtopic.php?f=5&t=433 ?
I run:

cd flash_download_tool_python2.6-2.7_wxpython3.0_release_v2.0_SOURCE
sudo python esptool.py --port /dev/ttyUSB0 --baud 9600 write_flash 0x00000 ~/Downloads/nodemcu_latest.bin --flash_size 32m --flash_mode dio --flash_freq 40m

But there is no command output, does nothing

@leonciokof
my esptool.py is download from https://github.com/themadinventor/esptool/blob/master/esptool.py.
and I test the esptool from http://bbs.espressif.com/viewtopic.php?f=5&t=433, also output nothing.

But now I use the wine+flash_download_tool.exe, which works fine, figure out my "File writes fail all the time" problem.

@vowstar Why is this closed? The bug is not fixed. Should this be reported on a different tracker?

I don't think that Wine + flash_download_tool.exe is a good enough solution when a feature of NodeMCU is cross-platform.

Thoughts?

from nodemcu-devkit-v1.0.

I think esptool might have got a fix. I have yet to test it, but the commit looks like it should work.

Has anyone tried esptool after July 8th?

from nodemcu-devkit-v1.0.

Just to let other know I was able to use the latest esptool (>July 8th) to flash the board.
