the files are for 2 MB or larger flash only. There is a problem with the AT firmware bin files of AT firmware from august 2018.

The RF tab of the Flash Download Tool is editor for the esp_init_data_default.bin. I knew i had to go back a version since the last version was only for 2mb flash, wil try going back 2 versions. I have tried all the numbers, all different boot files and all diffrent init data deufault. I have always just picked the one with the highest number I had to go back a version or two and then it started working fine. The last couple times I messed with the AT firmware, I found that the newest version (and maybe the one before that, I can't remember) didn't work. The quality of the documentation from this huge company for a product sold by the millions is lower than what I would accept in a volunteer project I did on the weekend. I have always just picked the one with the highest number, but it's just stupid that their documentation is so ambiguous. It's very annoying to me that the file names in the AT firmware supplied by Espressif don't match the file names in their documentation. Here a screenshot of the 'download tools'

However if i type the AT command in the serial monitor i get no response from the ESP. The previous sketch is removed, if i open the serial monitor i will nog get any messages anymore. The flashtool says finished after som seconds. I was assuming i needed boot_v1.6.bin since that is the AT firmware version i have, but i tried all three of them. I am not sure what to choose for the boot.bin file. 2048.new.5.bin so i went and downloaded the version before that that has the right file. So here i found out i can not use the latest version of AT since that one only has bigger user1. I follow the offcicial guide from Espressif chapter: 1.2.4.

Then we try to flash the standard AT firmware on there. This shows 8Mbit (picture below) so there i think we can confirm it's 8Mbit flash size? When i use the flash_download_tools_v3.6.5 from the Espressif site it will show me some information about the ESP Flash real size: 1048576 bytes = 8.3 megabits (Mbit)

Now when i upload the ESP8266 CheckFlashConfig from the esp8266 examples the serial monitor will give me this: Flash real id: 001420C2 I do have a switch installed so i can pull GPIO 0 to GND to get into flashing mode.
