Are you still trying to do this in an oninit() function, or are you trying the simple case?

You should be able to paste the setup stuff directly into the left side of the ide

update - it looks like it's the reference here: https://github.com/espruino/Espruino/blob/master/.travis.yml#L20

I've asked @tve to add it to the tar file.

Thanks Gordon.
For the esp8266 build the 1.5 boot loader is missing so flashing via serial fails:

There is an issue here:
https://github.com/espruino/Espruino/issues/912

This is part of the https://github.com/pfalcon/esp-open-sdk - so I'm not sure if its the ci-travis file that needs updating, or only the makefile.

https://github.com/espruino/Espruino/blob/master/Makefile#L1927

BOOTLOADER = "$(ESP8266_SDK_ROOT)/bin/boot_v1.4(b1).bin"
to
BOOTLOADER = "$(ESP8266_SDK_ROOT)/bin/boot_v1.5.bin"

Please take a picture of your wiring and do a table like this:

http://forum.espruino.com/comments/12997920/

Display     NodeMCU     ESP-12   Colour
LED         3V3         3V3       N/A
SCLCK       D5          GPIO14    Green
DN<MOSI>    D7          GPIO13    Yellow
D/C         D2          GPIO04    Orange
RST         D1          GPIO05    Brown
SCE         D8          GPIO15    Red
GND         GND         GND       Grey
VCC         3V3         3V3       Blue
BackLight   GND         GND       Purple

As you can see here NodeMCU.D7 is gpio13

I don't think your init it matching how you have wired up.

I think you need to simplify here.

Forgot about the oninit() and wifi stuff.

You want to get the simple case of the spi and init of the sd card sorted.

Have a look here:
http://forum.espruino.com/conversations/285779/#comment13002694
There might be some clues on how to setup your wiring..

The Nodemcu:D4 type set up may help instead of just using D4 if you are going by the labels on the board...

The code posted above was changed needed in the c code to compile... Not related

If you see v186.113 then you have the updated firmware.

Ignore the warning about the missing module - it is because the normal esp8266 does not have the module and the web Ide doesn't know it is available.

On the right hand side of the ide try:

>fs=require('fs');
=function () { [native code] }

You should see the 2nd line if the module loaded rather than undefined

Just flash the user1. User2 is used for ota(over the air) updates.
This is done using the wiflash.sh script.

@ManoBiletsky

Yes upload the .bin files with esptool - like you did for the initial firmware.

The block depends on which esp8266 board you have - just do what you did last time...

As far as code changes - you will need to initialize the spi to however you have wired up the sd card.

@ManoBiletsky
The zip file contains espruino_esp8266_user1.bin and espruino_esp8266_user2.bin

To compile:

export USE_FILESYSTEM=1
and I commented out USE_GRAPHICS in the Makefile as there is not enough space for both.

This change is also needed as the macro fails:

void jswrap_file_skip_or_seek(JsVar* parent, int nBytes, bool is_skip) {
  if (nBytes<0) {
    //jsWarn(is_skip ? "Bytes to skip must be >=0" : "Position to seek to must be >=0");
    if ( is_skip) jsWarn("Bytes to skip must be >=0");
    if ( is_skip <= 0 ) jsWarn( "Position to seek to must be >=0");
    return;
  }

I've not tested with an SD card - however the modules loads!

>fs=require('fs');

If I recall there was one line change required to get this to compile. You could try @jumjum online firmware builder, and turn on the fs module in the compile.

@Ducky

Correct - I've edited the post.

No it is much more than this. It is running Ubuntu, so you can apt-get packages. What I have shown above, installs perl, python, gcc and runs them natively. This is incredibly powerful!

Ok. Got the Esp8266 build working on windows 10!

You need to build the SDK as a standard user. This locked up the first time, however worked after a reboot.

To build the SDK there needs:

cd /mnt/c/ubuntu/
git clone https://github.com/pfalcon/esp-open-sdk
sudo apt-get install autotools-dev autoconf
sudo apt-get install make unrar autoconf automake libtool gcc g++ gperf     flex bison texinfo gawk ncurses-dev libexpat-dev python-dev python python-serial     sed git unzip bash help2man wget bzip2
ln -s /usr/bin/aclocal-1.14 /usr/bin/aclocal-1.15
ln -s /usr/bin/automake-1.14  /usr/bin/automake-1.15
cd esp-open-sdk/
make STANDALONE=n

this takes a while to compile!

then:

wget 'http://bbs.espressif.com/download/file.php?id=1021&sid=6e2aef8d5d8e700aca4a7b444c985e10' -O liblwip_536_for_ESP8266_NONOS_SDK_V1.5.0.zip
unzip liblwip_536_for_ESP8266_NONOS_SDK_V1.5.0.zip
cp liblwip_536.a ../esp-open-sdk/ESP8266_NONOS_SDK_V1.5.4_16_05_20/lib

cd ../Espruino

In the Makefile this needs to be updated to: 
boot_v1.4(b1).bin -> boot_v1.5.bin

cat ./build-esp-4mb.sh


#! /bin/bash
export ESP8266_BOARD=1
export FLASH_4MB=1
export ESP8266_SDK_ROOT=/mnt/c/ubuntu/esp-open-sdk/sdk
export PATH=$PATH:/mnt/c/ubuntu/esp-open-sdk/xtensa-lx106-elf/bin/
export ESPHOSTNAME=espruino:88
make $*

chmod +x ./build-esp-4mb.sh
./build-esp-4mb.sh

flash over the air from the bash shell:

./build-esp-4mb.sh wiflash

and then we have:

Seems to work!

The Anniversary Update (64 bit only) has a developer mode add on that allows Ubuntu code to run in a windows subsystem.

This means Espruino can be compiled without running in a VM!

The update has not been rolled out - here are the instructions to update manually...

http://www.howtogeek.com/248177/whats-new-in-windows-10s-anniversary-update/

Then turn on developer mode - reboot and add the Linux on windows system:
http://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

On my system - in the cmd prompt, I had this error message:
Unsupported console settings. In order to use this feature the legacy console must be disabled.

https://github.com/Microsoft/BashOnWindows/issues/319
Open cmd.exe
Right click title bar -> Properties -> Uncheck Use legacy console
Click OK

Then on first run of bash.exe, the sub system is installed.

Then:

cd /mnt/c
mkdir ubuntu
cd ubuntu
sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install gcc-arm-none-eabi git build-essential
git clone https://github.com/espruino/Espruino.git
cd Espruino
make

Then:

root@OFFICE-PC:/mnt/c/ubuntu/Espruino# ./espruino
Interactive mode.
Size of JsVar is now 32 bytes
Size of JsVarRef is now 4 bytes
Added SIGINT hook
Added SIGHUP hook
Added SIGTERM hook

Yay!

Will try a cross compile soon!

Not sure where you are running the mqtt stuff, this is an interesting article using docker on the raspberry pi

https://sample.me.uk/blog/post/rpi_docker_iot?mkt_tok=eyJpIjoiTVdNNE5tSTJPV0l3T1RWaiIsInQiOiJxcmdrck1JRmVLZUpDbVwvNGtuMUZHRTMwRUhcLzY1Zm9CZTY1MDgrWUZONFVUbEEzVUl0MmFpNEt0dmdJbnNlTzhzQXkzSjFWMk5aWGVTWm1McFZqUElsYkx5WlwvYmlNS0hNSXo0OTRTdk1Yaz0ifQ%3D%3D

Keep us posted on how you get on - it would brilliant if espurino and Bluetooth work on that!

Have a look here - this is using pipe with flash reads....

http://forum.espruino.com/conversations/283045/#comment12837928

It's a while back since I wrote it, but could before use.

Connected

Disconnected
echo(0);

I've had this issue with Windows 10. Even a reset on the board does not fix- it's to do with the USB to serial... If you unplug the USB and plug it in again - all will be fine.

It occurs after flashing....

As you have discovered, via wifi works well - it is about 4x faster than serial too.

For the sake of brevity - it looks like there are quite a few constants that are not used!

You could also shorten - COMMAND_xx to say C_xxx.

@Gordon - does the google closure compiler automatically do this - can the code above get passed through and then re-pretty printed to make it human readable again?

@ceremcem
http://www.espruino.com/Reference#l_Flash_getFree

require("flash").getFree()

This method returns an array of objects of the form {addr : #, length : #}, representing

contiguous areas of flash memory in the chip that are not used for anything.

You need to use wifi.save after connecting to have the settings save in flash.

You only need to do this once.

Might be too late to the party, but there is a new esp8285 chip - with 1mb flash built in....

http://tech.scargill.net/esp8285-in-the-flesh/

Each time you do an ota update, it alternates between user1 and user2.

I'm not sure if you can just add the user1 part, and then do an ota into user2 and boot into it? @tve ?
