"App is too big" error when building for ESP32

General

I keep getting the error below when trying to build the demo app locally or remotely for ESP32.

Build works for ESP8266 with “mos build --platform esp8266 --build-var BOARD=esp8266-1M”

Mongoose OS command line tool 2.13.1 on MacOS 10.14.4

Please share the exact build command line, and your mos.yml.

It has been fixed in latest:

mos version
The Mongoose OS command line tool
Version: 201905021612
Build ID: 20190502-161444/g6f34b9e-master
Update channel: latest
5

Unfortunately still doesn’t work for me.

What is the output of mos version?
Did you try mos build --platform esp32 --clean?
