ESP8266 boot error

Hi,

i would like to ask you.
I have yaml file in ESPHome and all works ok, but if i add one more sensor into my yaml, after flash, esp will not boot and turn on to safe mode…

Here is error code from ESP8266

19:39:16.481 → 3fffffc0: feefeffe feefeffe 3fffdab0 40100481

I dont know what is wrong. But if i removed this sensor from yaml - line 88 - 91 ESP boot ok and everything works ok. If i delete sensor odjezd1 and put here only odjezd 2 all works ok. Problem is only when there is two or more sensors…

I checked if ESP has RAM and flash size - but it looks ok too.

Can you help me? thank you

I have no idea if this will help you, but it’s worth a try:

First build a minimal configuration and flash that first. Then your normal configuration.

It helped me a long time ago.
The explanation back then was that flashing takes up far more memory than the actual code is big.
