This is a simple project template.
sample_lib is an example for multi-level folder Makefile, notice the folder structure and each Makefile, you can get the clue.
HOWTO:
1. Copy this folder to anywhere.
Example:
Copy to ~/workspace/project_template
You can rename this folder as you like.
2. Export SDK_PATH and BIN_PATH.
Example:
Your SDK path is ~/esp_iot_rtos_sdk, and want generate bin at ~/esp8266_bin.
Do follow steps:
1>. export SDK_PATH=~/esp_iot_rtos_sdk
2>. export BIN_PATH=~/esp8266_bin
SDK and project are seperate, you can update SDK without change your project.
3. Enter project_template folder, run ./gen_misc.sh, and follow the tips and steps.
Compile Options:
(1) COMPILE
Possible value: xcc
Default value:
If not set, use gcc by default.
(2) BOOT
Possible value: none/old/new
none: no need boot
old: use boot_v1.1
new: use boot_v1.2
Default value: new
(3) 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: 0
(3) SPI_SPEED
Possible value: 20/26.7/40/80
Default value: 40
(4) SPI_MODE
Possible value: QIO/QOUT/DIO/DOUT
Default value: QIO
(4) SPI_SIZE_MAP
Possible value: 0/2/3/4/5/6
Default value: 0
For example:
make COMPILE=gcc BOOT=new APP=1 SPI_SPEED=40 SPI_MODE=QIO SPI_SIZE_MAP=0
