ESP8266 Community Forum

HI All
I have never posted to any forum in my very long life, so apologies if this is the wrong place and wrong method.
I have been trying to update the firmware on ESP-01

I can flash the following:

AT version:0.21.0.0
SDK version:0.9.5

or

AT version:0.22.0.0(Mar 20 2015 10:04:26)
SDK version:1.0.0
compile time:Mar 20 2015 11:00:32

but despite days of effort and frustration NOT the following

v0.9.2.2 AT Firmware.bin
or
esp_iot_sdk_v1.5.0_15_11_27a (using the individual bin files)

or
ai-thinker-v1.1.1 (1).bin

I had one chip with ai-thinker-v1.1.1 and via Arduino uno and BLYNK could turn digital pins on and off and read analogue ports , but as soon as it was power cycled it went into continuous loop basically bricked.
Could not then flash v1.1.1 but only those listed above.
going crazy

if I posted incorrectly my apologies

HELP!

Heya,

please post the picture of your ESP-01, there is a very high probability that your ESP is 512k one.
Latest AT firmwares require at least 1M of flash RAM.

Hi Mozz

Thanks for your reply. That makes total sense.
I will get a pick up as soon as I can. It seems that I naively assumed that all I had to do was flash the down loaded bin files.
I guess I will have to learn about compiling etc., bit hard when your brain is as old and decrepit as mine

Cheers and thanks

Hi again

Just checked they are the black ones , as I understand it they are the 1meg ones.
Back to the drawing board.
