Software upload addresses and ESP8266 esp-12 E unresponsive on AT

Hello !!!

I have two problems
The first is at which address to upload the software /first two addresses in the name/.

0x00000.bin
0x10000.bin
blank.bin
esp_init_data_default.bin
nodemcu_integer_0.9.5_20150318.bin

The other thing is the module has 4 MB Flash/ ?
Either I am uploading the wrong software and to the wrong addresses or something else. The soft seems to load with ESP8266Flasher.exe but I have no response from the module in the terminal on AT ?
Can you please provide some proven soft and addresses where to upload ?
Thank you

If you don't upload AT firmware, then there will be no AT response in the terminal. In my footer you have a link to a post where you can find where to download the AT firmware for the ESP8266 (version 1.7 for 4MB flash).

Usually ESP-12Es have a flash size of 4 MB unless you have come across some "economy" version.

Which addresses to upload to?

0x00000 boot_v1.7.bin
0x01000 user2.2048.new.5.bin
0x3fc000 esp_init_data_default_v08.bin
0xfe000 blank.bin
0x3fe000 blank.bin

First, of course, you need to unpack the firmware package.

https://www.espressif.com/sites/default/files/ap/ESP8266_AT_Bin_V1.7.zip upload it and nothing No wifi or AT communication visible

Please show a screenshot of the flasher with the settings.
What speed do you have set in the serial terminal?

.

terminal 115200

.

The settings of the individual sections in the flasher look OK.
I was referring to the speed setting in the terminal. Which one are you using?

you have above Realterm

Do you have the COM port to the flasher and terminal open at the same time i.e. is the flasher closed as you use the terminal?
You need to reboot the ESP after uploading the firmware.

Please still show what you have in the flasher logs after uploading the firmware.

I disconnect the TTL converter from the USB laptop, disconnect the I00 from the ground and reconnect the converter to the USB

For the reset you only need .
Do you have GPIO 0 and GPIO 2 connected with a 10k resistor to the 3V3 supply?

I've got,mum Only gripo15 us to ground without resistor
My guess is that there is something wrong with my E 12 software.
Simply after uploading the software, the module does not stand up / does not transmit wifi / Either bad software or addresses, because on another without AT at least transmits wifi

I don't think unless it has less than 4 MB. You have not yet shown the flasher logs after uploading the firmware to the esp.

The AT firmware will not "sow" wifi after boot until you issue the appropriate AT commands.
The AT firmware you downloaded is from the manufacturer, and I have not had it fail to work on a working ESP-12 or ESP-07. You can, of course, still try with version 1.6.2.
Either there is something wrong with the serial terminal configuration, or with the ESP-12 connections themselves.

It's I don't know what it is I'm uploading according to the addresses what you gave I have two modules and it's the same on two of them. With both the converter and the adrurino I cannot communicate over AT

You can still try the alternative settings for version 1.7:
.

In the schematic GPIO16 is connected to RST permanently, it should be a diode in the direction to GPIO16, such a connection makes it impossible to upload the firmware properly, unless you disconnect this jumper while uploading. If there is to be a resistor on GPIO15 then give a resistor - it is always better to do exactly with the instructions to start with.
I always uploaded the AT firmware stating I had 1MB flash, even when I had 4, same settings for ESP12F/12E and 1MB ES01S:
.
and as you can see with another program.
If it doesn't work I reduce QIO, QOUT, DIO and finally DOUT in turn.
Newer firmware has the AT connection at 115200, older ones had 9600, I always check both.
Upload a sample sketch from the Arduino that prints something to Serial and see if it works properly.
When you connect the ESP to the PC set the terminal to 74k and do a reset, paste the boot message here - it says what is uploaded and what mode it boots into, maybe something is not connecting and despite using the switch it still only boots into flash upload mode.

Thank you for your help tonight I protest
when uploading you have BAUD 921600 or so set ?

Better not. This will limit the number of potential sources of problems when uploading.

During programming, GPIO16 does not need to be connected to anything at all. In the schematic it is connected to the RST to wake up the ESP from deep-sleep.

It would also be a good idea for you to use the Flash Download Tool for loading firmware mentioned by a colleague @kaczakat .
Link to post with attached program version 3.6.7:
https://www.elektroda.pl/rtvforum/topic3415731.html

Thanks to the diode from RST to GPIO16, it is possible not to move this connection any more and to have a permanent connection for wake-up, while at the same time flash uploading works. As someone doesn't intend to use sleep it is of course possible not to connect at all.
I set the speed to 900k as everything is OK, sometimes I need to reduce it to 115200, and there were times when I had to upload 9600, it depends on which cable and which module, which UART converter.

kol kaczakat in the picture you shared is user1.1048.new.5.bin and in the package is user1.2048.new.5.bin ?
The second issue I understand the diode strip for the RST ?

Led is a special case of a light-emitting diode, I am writing about a schottky diode or ordinary silicon diode of 0.6V, towards GPIO16 )there above I wrote wrong):
.

Attached is what I uploaded.
PS:
For the AT I don't see the point of connecting GPIO16 to the RST in any way, this is used to wake up every certain time with a code from the ESP level, that is when there is no other device controlling it.

After uploading your package, the terminal shows the following when connected to WiFi
+STA_CONNECTED:"a4:50:46:d5:88:e6"

+DIST_STA_IP:"a4:50:46:d5:88:e6","192.168.4.2"


After the AT+GMR command, it responds with AT+GMR
Strange that it responds to the command with the same /.

user1.1048.new.5.bin and user 2 are uploaded to the addresses you specified

while user1.2048.new.5.bin just uploads after 0c1000 and also wifi gets up

Strange, because uploading ESP8266_AT_Bin_V1.7 to the same addresses causes wifi not to work

After uploading everything, firing up the terminal at 115200 and pressing RST, the 74k speed rubbish should fly through first, followed by the READY text.
AT commands can now be typed in.
Configuration uploaded to a Wemos board with ESP12E and 4MB flash:
.
Post-GMR response:
.
Soft 1.71 is a bit more messed up, it worked in this setting:
.
.
I downloaded the soft from here: Link .

The case is as follows I have uploaded the soft ESP8266_AT_Bin_V1.7 and ESP8266_NonOS_AT_Bin_V1.7.1 according to the settings in the last picture for Soft 1.71
Soft loaded, I can see the network from the card . After a reset REDY.
Terminal responds correctly after setting in ardurino : Both NL and CR

Thank you !!!!
