Moje drobne zmiany i poprawki do oficjalnego SDK

v5.2.0

• Windows
• Mac
• Linux(64)
• Linux(32)

If you are still using old version SDK(< 3.0), please use toolchain v4.8.5, as following:

• Windows
• Mac
• Linux(64)
• Linux(32)

Besides the toolchain (that contains programs to compile and build the application), you also need ESP8266 specific API / libraries. They are provided by Espressif in ESP8266_RTOS_SDK repository. To get it, open terminal, navigate to the directory you want to put ESP8266_RTOS_SDK, and clone it using git clone command:

cd ~/esp
git clone https://github.com/michalzd/ESP8266_RTOS_IDS.git

ESP8266_RTOS_SDK will be downloaded into ~/esp/ESP8266_RTOS_SDK.

copy workspace/project_template to another folder start project configuration utility menuconfig

make menuconfig

IDF_PATH environment variable set in project Makefile

You are almost there. To be able to proceed further, connect ESP8266 board to PC, check under what serial port the board is visible and verify if serial communication works. Note the port number, as it will be required in the next step.

make all

... will compile app based on the config.

When make all finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this from make by running:

make flash

This will flash the entire project (app, bootloader and init data bin) to a new chip. The settings for serial port flashing can be configured with make menuconfig.

You don't need to run make all before running make flash, make flash will automatically rebuild anything which needs it.

The make monitor target uses the idf_monitor tool to display serial output from the ESP32. idf_monitor also has a range of features to decode crash output and interact with the device. Check the documentation page for details.

Exit the monitor by typing Ctrl-].

To flash and monitor output in one pass, you can run:

make flash monitor or 'screen /dev/ttyUSB0'

After the initial flash, you may just want to build and flash just your app, not the bootloader and init data bin:

• make app - build just the app.
• make app-flash - flash just the app.

make app-flash will automatically rebuild the app if it needs it.

(In normal development there's no downside to reflashing the bootloader and init data bin each time, if they haven't changed.)

Note: Recommend to use these 2 commands if you have flashed bootloader and init data bin.

ESP8266_RTOS_SDK supports compiling multiple files in parallel, so all of the above commands can be run as make -jN where N is the number of parallel make processes to run (generally N should be equal to or one more than the number of CPU cores in your system.)

Multiple make functions can be combined into one. For example: to build the app & bootloader using 5 jobs in parallel, then flash everything, and then display serial output from the ESP32 run:

make -j5 app-flash monitor

The make flash target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state. To erase the entire flash, run make erase_flash.

This can be combined with other targets, ie make erase_flash flash will erase everything and then re-flash the new app, bootloader and init data bin.
