Post #23 has my solution, once again huge thanks to Juraj
As the title says, i have some trouble getting the AT firmware on my ESP8266 module. This is the one i have.
For the programmer i use this little device
I do have a switch installed so i can pull GPIO 0 to GND to get into flashing mode.
Now when i upload the ESP8266 CheckFlashConfig from the esp8266 examples the serial monitor will give me this:
Flash real id: 001420C2 Flash real size: 1048576 bytes Flash ide size: 524288 bytes Flash ide speed: 40000000 Hz Flash ide mode: DOUT Flash Chip configuration wrong!
Not sure what to make of that. Flash real size: 1048576 bytes = 8.3 megabits (Mbit)
When i use the flash_download_tools_v3.6.5 from the Espressif site it will show me some information about the ESP This shows 8Mbit (picture below) so there i think we can confirm it's 8Mbit flash size?
Then we try to flash the standard AT firmware on there. This will not succeed. I follow the offcicial guide from Espressif chapter: 1.2.4. 8 Mbit Flash
blank.bin - 0xFB000 esp_init_data_default.bin - 0xFC000 blank.bin - 0x7E000 blank.bin - 0xFE000 boot.bin - 0x00000 In /bin/at user1.1024.new.2.bin - 0x01000 In /bin/at/512+512
So here i found out i can not use the latest version of AT since that one only has bigger user1.2048.new.5.bin so i went and downloaded the version before that that has the right file.
I am not sure what to choose for the boot.bin file. There is boot_v1.2.bin boot_v1.6.bin boot_v1.7.bin
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. Also the esp_init_data_default.bin has esp_init_data_default_v05.bin esp_init_data_default_v08.bin I can not find out witch one to choose.
The flashtool says finished after som seconds. The previous sketch is removed, if i open the serial monitor i will nog get any messages anymore.
However if i type the AT command in the serial monitor i get no response from the ESP.
Here a screenshot of the "download tools"
So anybody got any idea what is going on here? If i forgot to give some other information that is needed please let me know i tried to give everything i know ;) :P
