How to re-flash an ESP?

[Tobi993]

Hello all,

I have a few Wemos D1 mini and I want to put a new software on it.
So I tried to re-flash the devices by the Flashtool, but all devices don't start.
The flashtool reported success before.
I do not see them in my WiFi net or as an access point.

I tried V2.0.0 dev 12, 20180118 and the newest 20180209
What do I wrong?

You may have settings left on the unit? Reset command will erase the configuration file.

Now it works.
I tried the old R120 Version, then I had this ESP_0 AP.

I don't know why just the old version works for re-flashing!

Because you previously had Rxx version on it with that versions config file.

Maybe it's the same problem like many others. The flash-chip only works in DOUT-mode.
Test the image from TD-er and flash it from commandline with this batch:

Code: Select all

@echo off
set /p comport= Comport (example 3, 4, ..)           :
esptool.exe -vv -cd nodemcu -cb 115200 -cp COM%comport% -ca 0x00000 -bm dout -cf ESPeasy_v2.0.0-2018-02-08_DOUT.bin
pause

Yes you're right. That's probably the answer.

Hmm if it's more common, we should perhaps change all the 1M builds to DOUT mode?

[grovkillen]

Yeah we might need to do that.
