Program Size too Large

[hectorvanzyl]

Hi, when trying to write code to ESP32 I get following error after multple attempts and removing unneccessary lines not required for Sunsynk. HARDWARE: ESP32 240MHz, 320KB RAM, 4MB Flash

Hi. Have you tried to disable the webserver?

[hectorvanzyl]

Hi, yes webserver entry was completely removed from yaml.

Not sure what the issue is. Did you try a clean build? This is mine with everything enabled

I did try clean build, also did a "python -m esptool --chip esp32 erase_flash" to ensure memory have no leftovers, installed ESPHome and tried to upload code, starting to have my doubts regarding the dev board as the size discrepency do not make sense.

just started from scratch again, still geting same error, is there perhaps anything in the dependency graph that could cause the issue, if so how do I go about to remove it.

Are you using the correct board

esp32:
  board: esp32dev
  framework:
    type: arduino

[hectorvanzyl]

Exactly as above yes.

I think I'm wasting your time with an issue with the board, it's one of the 1st ESP32 dev boards released, I'm waiting for new ones. Thanks for your time and brilliant code shared, it's truly appreciated. Best wishes.
