Did you try additional reset?

[asm7100]

What do you meen?

[asm7100]

I flash Nodemcu to it by the firmware uploader program, thats works.

But not with the Arduino IDE

[asm7100]

No help to get?

Could you try stable R20 on that module and see it that works?

[asm7100]

Yes with R20 its work.
But anoter ESP12 Modul and this moduel is from the same store
The first one, was fine, but not the other.
I will try to flash it with R29 when i have set it up, i R20

[asm7100]

It work with R20, now i have flash it with R29, and get this when i boot it up.

There's something going wrong during flash writing. I have not seen this before in my test lab.
R20 and R30 use a different flash memory area to store it's configuration, so that could explain different behavior.

Are more people experiencing the same issue?

Side note: If your unit get's stuck in a flash erasing loop, better remove the sketch (by using an older release or just program a blink sketch) or power off the ESP module until you have a solution. The ESP flash memory may wear out on that particular sector and may become defective after a number of writes. Don't now the exact maximum of write cycles but with AVR is was >100.000

Its running with R20 for now.
But its strange is that the first (Called esp120) is running R29
But this one i call 121 can' t run R29, but is now running R20

[asm7100]

Now i have tried R37 or??? 36.

And it still the same.
