ESP8266 D1 mini fails to execute code after exiting deepsleep

Hi.
I have a problem with the ESP8266 D1 mini (specifically this board: https://www.aliexpress.com/item/D1-mini-Mini-...ment-board-based-ESP8266-by/32651747570.html).

The problem is that after exiting deepsleep (which can be seen on the port monitor in the Arduino IDE), the board no longer executes code. Only something like this appears on the console:

ets Jan 8 2013,rst cause:5, boot mode:( 3,6)

ets_main.c

Nothing happens after that. If I press reset again I get this:

ets Jan 8 2013,rst cause:2, boot mode:( 3,6)

And the program still does not stratify.
I press reset again and then only the program starts.

I've tried some more with shorting D0 and RST (although apparently on this board you don't need to), but the end result is similar, only cause is "2".

ets Jan 8 2013,rst cause:2, boot mode:( 3,6)

What is wrong. A broken board? If I am not using deepsleep then the tile is working correctly.
Deepsleep is fired by the command:
ESP.deepSleep(10 * 1000000);
I have tried even the simplest application which does nothing but send a teskt to the serial - it does not help.

If you do something before sleep then add some delay, I guess you should decide what to do with the radio after waking up:

You have possible options in your comment.
I understand you have an IO16 connected to the RST?
SLEEP_TIME2 simply is the number defined at the beginning of the sketch.
Edit:
GPIO16 is just D0 on the Wemos, but always check the pinout of the board, those Dcos markings can sometimes be confusing on different boards. And in my case I have it connected to RESET with a cable to make it work. When it's connected I have trouble programming, so it's not likely to be done permanently on any board. I remove this connection for the duration of programming.

Check that in this Wemos you actually have D4 (GPIO2) and D3 (GPIO0) connected via resistors to the 3V3 supply. It is also safe to insert additional such resistors of 10k for testing.

This is what the board looks like up close - can anyone take a peek: https://photos.app.goo.gl/tBWyDVT9Ks8JPHi86
As for this WAKE_RFCAL I have taken it to a lower level ie it also doesn't wake up in an app where there is no wifi. As far as programming goes, obviously there is no D0/RST jumper when uploading the app,

I recently had some crappy Wemos board, powered from USB it worked with varying degrees of efficiency, the problem was solved when I powered it directly to the 5V pin. Maybe you have one from the same series? I actually used it for a server with WIFI and after a random time it stopped working.

What type of ESP8266 board do you have set up in the Arduino IDE?

I checked the external power supply (PIN G and PIN 5V) - the board works, but the effect is the same i.e. after connecting the power supply the application connects to the wifi, then I give the application deepsleep for 10 seconds, after this time you can see that the board wakes up (short LED flashing), but the connection to the wifi does not happen. So exactly the same as when powering up via USB.

As for what is selected in the Arduino IDE, I have it set to: LOLIN(WEMOS) D1 R2 & mini.
PS. I've tried refalsh - in both the factory firmware and Ai-Thinker exactly the same thing happens.

Well then, show an example of the code you are using.

Try compiling and loading the code with the board set to "Wemos D1 R1".

You can't see much from your photo, but from what I've found out it's a hardware problem, take a peek if your ESP8266 looks like this:
.
well one of mine looks like this and there is the same problem with it. The reset signal from GPIO16 (D0) is too short and ineffective. Quite a few people have this problem, you will have to be careful when buying, https://github.com/esp8266/Arduino/issues/6007.
Several people have replaced the Wemos mini board with the ESP module described DOIT - as in the photo above.

This is exactly the chip - DOIT.AM. I read the thread you provided and the same behaviour is described there.
I can already see that I have to advertise this board to the dealer and look for another one.
Thank you for providing this link!

This does not refer directly to the "DOIT.AM chip", but to the ESP-12S version that may have been used in your module. The ESP-12S is such an "economical" clone, coming in different variants: without or with an extra row of pins.

The ESP-12S should simply be avoided. There may also be an AI-Thinker logo on such modules, but AI-Thinker no longer produces these modules for 3 years.

I think mine is "EX" - This is what the Arduino IDE displays to me:

esptool.py v2.6
Serial port COM5
Connecting....
Chip is ESP8266EX
Features: WiFi

So the problem is probably wider than that.

That's OK, that's the official name for the EP8266 chip.

It's not likely to apply only to the ESP-12S since people are reporting problems with the ESP-12F there (that's where the thread started). It's also hard to tell from the logo on the tin how the chip will behave, as you can probably order with your design ( and necessarily with FCC lettering). It's half bad as I ordered one Wemos module at all in the last year, but some people bought 100 chips there and don't know what to do with them. The ESP-12S module is immediately recognisable from the casing, the flash pins are not routed to the bottom edge. I still have a soldered module on an ESP-12 board and that didn't wake up either, but it was the first one I bought and I just figured that type had it that way.
