Until now, the ESP8266 target used a non-tagged git hash revision of the RTOS SDK (from Oct 2017). Moreover, the compiler was also a custom-built gcc. This commit sets the RTOS SDK version to v2.1.0, released Oct 2018, which is the latest old-style SDK for ESP. The commit also changes the used gcc to an Espressif-provided pre-built toolchain, which is tagged for the (latest) v3.0.1 SDK release. (The SDK bump is not to the latest SDK version because the new v3.x line of the SDK is "ESP-IDF style", which is incompatible with the current target code base. On the other hand, the toolchain comes from the latest SDK release because the v2.x line had no pre-built toolchain suggestions -- but it builds v2.x sources correctly.)

#### Preparation
|
|
|
|
##### Accessories
|
|
|
|
You need,
|
|
* 3.3V power supply. You can use bread board power (+5V, +3.3V). I used LM317 like this;
|
|
* Use [LM317](http://www.ti.com/lit/ds/symlink/lm317.pdf)
|
|
* R1 = 330 Ohm, R2 = 545 Ohm (1K + 1.2K in parallel)
|
|
* 5V 2A adaptor
|
|
* USB to RS-232 Serial + RS-232 Serial to Digital or USB-to-RS232 TTL converter
|
|
|
|
#### Tools
|
|
|
|
The rest of this document will assume that you download all necessary tools into
|
|
a common directory structure. For the sake of simplicity, `$HOME/Espressif` will
|
|
be used as the root of this structure. Feel free to deviate from this but then
|
|
adapt all the paths accordingly.
|
|
|
|
```
|
|
mkdir $HOME/Espressif
|
|
```
|
|
|
|
##### Toolchain
|
|
|
|
Download the [toolchain](https://github.com/espressif/ESP8266_RTOS_SDK/tree/v3.0.1#get-toolchain)
|
|
pre-built for your development platform to `$HOME/Espressif` and untar it. E.g.,
|
|
on Linux/x86-64:
|
|
|
|
```
|
|
cd $HOME/Espressif
|
|
tar xvfz xtensa-lx106-elf-linux64-1.22.0-88-gde0bdc1-4.8.5.tar.gz
|
|
```
|
|
|
|
##### Espressif SDK: use Espressif official
|
|
|
|
```
|
|
cd $HOME/Esprissif
|
|
git clone https://github.com/espressif/ESP8266_RTOS_SDK.git -b v2.1.0
|
|
```
|
|
|
|
This version is tested and works properly.
|
|
|
|
##### ESP image tool
|
|
```
|
|
cd $HOME/Espressif
|
|
wget -O esptool_0.0.2-1_i386.deb https://github.com/esp8266/esp8266-wiki/raw/master/deb/esptool_0.0.2-1_i386.deb
|
|
sudo dpkg -i esptool_0.0.2-1_i386.deb
|
|
```
|
|
|
|
##### ESP upload tool
|
|
```
|
|
cd $HOME/Espressif
|
|
git clone https://github.com/themadinventor/esptool
|
|
```
|
|
|
|
##### Set environment variables
|
|
|
|
Set environment variables, might also go in your `.profile`:
|
|
```
|
|
export PATH=$HOME/Espressif/xtensa-lx106-elf/bin:$PATH
|
|
export SDK_PATH=$HOME/Espressif/ESP8266_RTOS_SDK
|
|
export ESPTOOL_PATH=$HOME/Espressif/esptool
|
|
export BIN_PATH=(to output folder path)
|
|
```
|
|
|
|
#### Test writing with Blinky example
|
|
|
|
##### Get the source
|
|
|
|
found one example that works with SDK V1.2 (which is based on FreeRTOS, as of writing)
|
|
|
|
* https://github.com/mattcallow/esp8266-sdk/tree/master/rtos_apps/01blinky
|
|
|
|
|
|
##### Compile
|
|
|
|
Read `2A-ESP8266__IOT_SDK_User_Manual_EN` document in
|
|
[this](http://bbs.espressif.com/viewtopic.php?f=51&t=1024) link.
|
|
|
|
It's configured 2048KB flash
|
|
```
|
|
BOOT=new APP=1 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=5 make
|
|
BOOT=new APP=2 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=5 make
|
|
```
|
|
|
|
or old way... this works not sure this is ok.
|
|
```
|
|
make BOOT=new APP=0 SPI_SPEED=80 SPI_MODE=QIO SPI_SIZE_MAP=2
|
|
```
|
|
|
|
##### Flashing
|
|
|
|
* power off ESP8266 board
|
|
* connect GPIO0 to GND, connect GPIO2 to VCC
|
|
* power on
|
|
* write
|
|
|
|
```
|
|
sudo $HOME/Espressif/esptool/esptool.py \
|
|
--port /dev/ttyUSB0 write_flash \
|
|
0x00000 $SDK_PATH/bin/"boot_v1.7.bin" \
|
|
0x01000 $BIN_PATH/upgrade/user1.2048.new.5.bin \
|
|
0x101000 $BIN_PATH/upgrade/user2.2048.new.5.bin \
|
|
0x3FE000 $SDK_PATH/bin/blank.bin \
|
|
0x3FC000 $SDK_PATH/bin/esp_init_data_default.bin
|
|
```
|
|
_change `/dev/ttyUSB1` to whatever you have._
|
|
|
|
or the old way...this works not sure this is ok.
|
|
```
|
|
cd $BIN_PATH
|
|
sudo $HOME/Espressif/esptool/esptool.py \
|
|
--port /dev/ttyUSB0 write_flash \
|
|
0x00000 eagle.flash.bin 0x40000 eagle.irom0text.bin
|
|
```
|
|
|
|
* power off
|
|
* disconnect GPIO0 so that it is floating
|
|
* connect GPIO2 with serial of 470 Ohm + LED and to GND
|
|
* power On
|
