Problem building v1.96 + filesystem to ESP8266

Thanks @Wilberforce, that worked. I can now use the save() and on reboot everything work fine.

To be clear on the process, this is my modified python script:

import os;
import pinutils;
info = {
 'name'            : "ESP8266",
 'espruino_page_link' : 'EspruinoESP8266',
 'default_console' : "EV_SERIAL1",
 'default_console_baudrate' : "115200",
 'variables'       : 1600,
 'binary_name'     : 'espruino_%v_esp8266_4mb',
 'build' : {
   'libraries' : [
     'NET',
     'TELNET',
     #'GRAPHICS',
     'CRYPTO',
     'NEOPIXEL',
     'FILESYSTEM',
     'FLASHFS'
   ],
   'makefile' : [
     'FLASH_4MB=1',
     'ESP_FLASH_MAX=962560',
     'FLASH_BAUD=460800'
    ]
 }
...

This is my compile.sh

 #!/bin/bash
export FAMILY=ESP8266
export BOARD=ESP8266_4MB
export FLASH_4MB=1
export ESP8266_SDK_ROOT=/espruino/ESP8266_NONOS­_SDK-1.5.4
export PATH=$PATH:/espruino/esp-open-sdk/xtensa­-lx106-elf/bin/
export COMPORT=/dev/ttyS2
export USE_ESP8266=1
export RELEASE=1
make clean && make $*

And this is my flashing command using 1024/1024:

esptool.py --port COM8 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB-c1 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x3FC000  esp_init_data_default.bin 0x3FE000 blank.bin

There is only one question remaining, I've added the RELEASE=1 again to compress a little bit more the binary, and upon restarting if I'm connected do espruino IDE I get the following output

If I open a PuTTY session, with a baud rate of 75600, I can read the printed message:

Is there any way to remove that from startup?

Thanks again.
