neutree / esp8266-nonos-sdk

some optimization based on official esp8266 nonos sdk 2.0

Feature

• based on espressif nonos sdk v2.0
• integrate esptool and set default download baudrate as 1500000
• driver and project can be built directly at you first get this project

How To Use

1. clone this project

git clone https://github.com/Neutree/esp8266-nonos-sdk.git

2. install docker

3. create container(set up compile environment and download tool etc.)

• pull docker image:

docker pull neucrack/esp-build
or
docker pull daocloud.io/neucrack/esp-build

• plug in you device(eg:node mcu)
• create a container

docker run -ti --name esp8266-builder --device /dev/ttyUSB0:/dev/ttyUSB0 -v dir:/build neucrack/esp-build /bin/bash

the dir is the direction of esp8266-nonos-sdk project when pull and run completed, the next time you want use this container by

docker start esp8266-builder
docker attach esp8266-builder

4. build project and download to board

run in container

cd /build/esp8266-nonos-sdk
make flash

build options:

make           : compile project
make flash     : compile and upload code to flash of board
make erase     : erase all data in flash
make monitor   : serial monitor tool
make clean     : clean binary files
make distclean : clean binary files and folders
make help      : help info

parameters:

(1) ESPPORT
	Default:/dev/ttyUSB0
(2) DOWNLOADBAUD
	Default:1500000
(3) COMPILE
    Possible value: gcc
    Default value: gcc
    If set null, will use xt-xcc.
(4) BOOT
    Possible value: none/old/new
      none: no need boot
      old: use boot_v1.1
      new: use boot_v1.2+
    Default value: new
(5) APP
    Possible value: 0/1/2
      0: original mode, generate eagle.app.v6.flash.bin and eagle.app.v6.irom0text.bin
      1: generate user1
      2: generate user2
    Default value: 1
(6) SPI_SPEED
    Possible value: 20/26.7/40/80
    Default value: 40
(7) SPI_MODE
    Possible value: QIO/QOUT/DIO/DOUT
    Default value: DIO
(8) SPI_SIZE_MAP
    Possible value: 0/2/3/4/5/6
    Default value: 2
For example:
    make COMPILE=gcc BOOT=new APP=1 SPI_SPEED=40 SPI_MODE=DIO SPI_SIZE_MAP=2
You can also use gen_misc to make and generate specific bin you needed.
    Linux: ./gen_misc.sh
    Windows: gen_misc.bat
    Follow the tips and steps by steps.

5. monitor serial output

use serial monitor:

• when linux ,use minicom or screen use minicom

sudo apt install minicom
sudo minicom -s  (setting /deb/ttyUSB0 115200 8n1)
sudo minicom -c on

exit minicom:
ctrl+A -> X -> Enter
or use screen

screen /dev/ttyUSB0 115200

exit screen:
ctrl+A -> K -> Y

• when docker,use:

make monitor

(pay attenrion, RTS and DTR are locked, so push reset button will not functional, use ctrl+T->ctrl+H to see help)

• when windows,use serial monitor with GUI,such as UartAssist.exe

directories description

src           source code
|---driver    driver source code
|---include   include files
|---user      user main

you can copy example from exampleto src,or delete example to make project clean~~
