Easily compile and flash binaries for the ESP8266 and ESP8266EX

You might also be interested in the branch for the ESP32: https://github.com/T-vK/docker-esp-sdk/tree/esp32

1. Get Docker

• If you trust me, you can simply pull my image from the docker hub:

  sudo docker pull tavk/esp-sdk:0.1.0

• Otherwise, if you want it to be built on your computer (takes about 30-90 minutes), run this:

  git clone https://github.com/T-vK/docker-esp-sdk.git
  cd docker-esp-sdk
  sudo docker build -t tavk/esp-sdk:0.1.0 .

Done!

How to use

Compiling binaries

sudo docker run -t -i -u esp \
-v /home/ubuntu/esp8266/esp-open-sdk/examples/blinky:/home/esp/shared_project \
-e SDK_VERSION='1.5.3' \
tavk/esp-sdk:0.1.0 \
make

• Replace /home/ubuntu/esp8266/esp-open-sdk/examples/blinky with the absolute path to the directory of the project oyu want to compile.
• Replace 1.5.3 with whatever version of the ESP SDK you want to compile. 1.4.0 up to 2.0.0 are supported.
• Replace make with whatever command is necessary to compile your binary/binaries.

Flashing binaries

sudo docker run -t -i -u esp \
--device=/dev/ttyUSB0 \
-v /home/ubuntu/esp8266/esp-open-sdk/examples/blinky:/home/esp/shared_project \
tavk/esp-sdk:0.1.0 \
esptool.py --port /dev/ttyUSB0 write_flash 0x00000 blinky-0x00000.bin 0x40000 blinky-0x40000.bin

• Replace /home/ubuntu/esp8266/esp-open-sdk/examples/blinky with the absolute path to the directory that contains the files you want to flash.
• Replace /dev/ttyUSB0 with the COM port that your ESP is connected to.
• Replace esptool.py --port /dev/ttyUSB0 write_flash 0x00000 blinky-0x00000.bin 0x40000 blinky-0x40000.bin with whatever command is necessary to flash your binaries.

Flashing bootloaders

sudo docker run -t -i -u esp \
--device=/dev/ttyUSB0 \
-v /home/ubuntu/projects/esp-bootloader:/home/esp/shared_project \
tavk/esp-sdk:0.1.0 \
esptool.py --port /dev/ttyUSB0 write_flash --flash_mode dio --flash_size 32m 0x0 bootloader.bin

• Replace /home/ubuntu/projects/esp-bootloader with the absolute path to the directory that contains the files you want to flash.
• Replace /dev/ttyUSB0 with the COM port that your ESP is connected to. -Replace esptool.py --port /dev/ttyUSB0 write_flash --flash_mode dio --flash_size 32m 0x0 bootloader.bin with whatever command is necessary to flash your binaries.

If the make file takes care of compiling AND flashing

sudo docker run -t -i -u esp \
--device=/dev/ttyUSB0 \
-v /home/debian/espusb:/home/esp/shared_project \
-e SDK_VERSION='1.5.3' \
tavk/esp-sdk:0.1.0 \
make ESP_ROOT=/home/esp/esp-open-sdk burn

• Replace /dev/ttyUSB0 with the COM port your esp is connected to.
• Replace /home/debian/espusb with the absolute path to directory of the project you want to compile/flash.
• Replace 1.5.3 with whatever version of the ESP SDK you want to use for the compiling process.
• Replace make ESP_ROOT=/home/esp/esp-open-sdk burn with the command necessary to compile and flash your project.

Tested

I personally tested the docker image under Ubuntu 16.04 x64 and Debian 8 Jessie x64.

Can I use this on Windows?

Yes, but docker doesn't run natively on Windows. Tools like boot2docker or docker-machine create a Linux VM using VirtualBox. So in order to grant the docker image access to your serial port and your project folder you have to pass your serial port (or usb serial adapter) through to the vm and the same applies for your project folder.
Read this for more information on that: http://stackoverflow.com/questions/30864466/whats-the-best-way-to-share-files-from-windows-to-boot2docker-vm

Can I use this on Mac OS X?

Probably yes. If docker runs natively on Mac OS X, then there is no need to do anything special. Otherwise follow the same steps that are required for Windows as described above.
