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
