1.8.7 fails to install

Post by klankschap » Sat Jan 28, 2017 1:24 pm

i tried to flash the latest 1.8.7 firmware into the esp8266 nodemcu amica
however it will result in continuous text dump on the screen.
version 1.8.6 gives similar results

version 1.8.4 does work.
How to proceed?

Based on your observations I think this post might help you:
viewtopic.php?f=16&t=2625&hilit=flash+size+esptool

I suggest also to flash with 115200 BAUD

Here is how I use esptool to flash micropython

Code: Select all

esptool.py --port COMx erase_flash
esptool.py --port COMx --baud 115200 write_flash 0 esp8266-20161110-v1.8.6.bin

python2 esptool.py -p /dev/tty.SLAB_USBtoUART --baud 460800 write_flash --flash_size=8m -fm dio 0 $@

and changing it into:

#!/usr/bin/env bash
python2 esptool.py -p /dev/tty.SLAB_USBtoUART erase_flash
python2 esptool.py -p /dev/tty.SLAB_USBtoUART --baud 115200 write_flash 0 $@

did not help

It works fine with firmware version 1.8.4

I had the same issue when trying to burn the latest firmware to a new Amica nodeMCU board.
Adding -fm dio to the write_flash did help.

Code: Select all

esptool.py --port /dev/ttyUSB0 erase_flash
esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash -fm dio 0 ../esp8266-20170208-v1.8.7-205-g181f7d1.bin

This is reproducable.
After flashing without -fm dio:

The firmware is in this exception loop.

After flashing with -fm dio a get a normal prompt:

Code: Select all

Type "help()" for more information.

BTW. I don't know what -fm dio actually is doing.

with espwritex defined as:

then then flashing the esp8266:

then reset the unit

Is it possible that erase and flash overlap?

I can somehow reproduce your problem when flashing with --flash_size=8m on a 4MB board.
When i flash with --flash_size=32m it is working.

Sorry i have no more ideas what could be wrong.
