    Hi guys,

    I noticed that I have less memory available when I build from sources than then already available firmwares

    I did the tests with the release 2V01 and ESP32 board. These are the results:

    Downloaded Firmware RELEASE 2V01

    File sizes:

       15168 abr 16 10:34 bootloader.bin
     1346960 abr 16 10:34 espruino_esp32.bin
        3072 abr 16 10:34 partitions_espruino.bin
    

    Info from Espruino IDE:

    >reset();
    =undefined

    I have a total of 2900 memory units in the custom build over the 4000 in the downloaded firmware (BLE is disabled). I think is a big difference for the same version (NOTE: The ESP32 toolchain used is xtensa-esp32-elf-linux64-1.22.0-73-ge28a­011-5.2.0.tar.gz)

    Anyone knows what could be the reason?

    Thanks,
    Jose.
