Okay, so the error here appears to be on the baud rate. Set it 115200 instead of 460800. The espruino IDE can't recognize such a high baud rate, and won't be able to communicate with the board. This is what the command should look like:
python "../esptool/esptool.py" --port COM46 --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.binBy the way, you can install esptool using the pip manager for python. For me it's just a little bit more convenient.
EDIT: grammar.

@Joshua_Sturmvogel If you flash only with 4m, the flash map will be set to 512/512, and the firmware will be too big to fit on the ESP memory, which will make it crash and printout a lot of errors. Try what Willberforce suggested, or updating your esptool.py to a more recent one. Just don't flash with the single 4m for it will not work.

Hello @Joshua_Sturmvogel, sorry for the delay in the response. I can share the firmware with you. Attached is my compiled version, based on the v1.96 release. This version is compiled with the following modules:
NET TELNET CRYPTO NEOPIXEL FILESYSTEMNote that it will only work in a 4mb ESP8266. Mine specifically is a NodeMCU V3.
Best Regards.
EDIT:
To be able to flash it without problems, you have to use the 1024/1024 flash map. Here is the esptool.py command for that:
esptool.py --port [/dev/ttyUSB0|COM1] --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.binEDIT 2: Corrected the baud rate for the flashing command.

I have tried the SD card and it didn't work, now I know why.
I have just asked about turning off those boot messages because I didn't recall them appearing on the stock Espruino firmware.
I will recompile it turning flashfs off, and since the messages aren't really doing anything negative, I'll just leave them there.
Thanks again for all the help.

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

Thanks again.

Hello @MaBe, I've also tried building with export RELEASE=1, and got the same error.
@Wilberforce Thanks for the insight, I may tweak a little on the packages. So far I don't need the graphics, do you know a way to omit it from the build?

Beyond what I posted earlier, here is a web IDE console output whenever I upload a code:
My code:
var wifi = require("Wifi"); wifi.setHostname("Espruino"); wifi.stopAP(); wifi.setIP({ip:"192.168.1.20",gw:"192.168.0.1",netmask:"255.255.255.0"},function(err){}); wifi.connect("SSID",{password:"PASS"},function(err){ console.log("connected? err=",err,"info=", wifi.getIP()); wifi.save(); }); SPI1.setup({mosi:D7,miso:D6,sck:D5}); E.connectSDCard(SPI1,D8); var files = require('fs').readdirSync(); for (var i in files) console.log("Found File" + files[i]);Console Output:

Hello, I'm fairly new to Espruino and recently bought a NodeMCUv3(esp8266). I've downloaded the latest releases and tested a few codes. I was developing a simple web server that would serve an html/css/js page, and the plan was to store them on an SD card.
The problem is that ESP8266 doesn't have FS by default, so I've set to build my own firmware with fs enabled. While I can build and get all my binaries, if i ever type save() on the web IDE and hard reset the board, it prints like crazy "fatal exception(3)"
Here are my codes:
compile.sh
#!/bin/bash export FAMILY=ESP8266 export BOARD=ESP8266_BOARD 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_FILESYSTEM=1 export USE_NET=1 export USE_ESP8266=1 export DEBUG=1 make clean && make $*flashing command:
esptool.py --port COM8 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.binI am running ubuntu on windows for compiling, and had to modify the ESP8266_NONOS_SDK c_types.h lines:
//typedef unsigned long uint32_t; typedef unsigned int uint32_t; //typedef signed long int32_t; typedef signed int int32_t;Beyond that, I couldn't find how to not use a certain module, for example neopixel, which made me modify the c_types.h
I'm also uploading my binaries if anyone wants to test them
Any help on this matter is greatly appreciated.
Thanks!
This output still looks like a baud rate problem. Did you reflash the firmware with 115200? If you open a putty on 460800 does the output change?
