1. I want make my example, and e.g. modify 01_helloword sdkconfig file and add example part of 02_blink,
I add below to 01 example,

#
# Example Configuration
#
CONFIG_BLINK_GPIO=5

but the config file recover to default and after type make, and make menuconfig can't load the "example configuration"
please give advise.

The blink GPIO configuration option is custom to the blink example, and is defined in examples/02_blink/main/Kconfig.projbuild and used in the code that blinks the LED in examples/02_blink/main/main.c. It does not make any sense in the 01_hello example: there is no code that uses it and there is no Kconfig code that defines what CONFIG_BLINK_GPIO is and how it should show up in the make menuconfig menu. That is why the program interpreting the sdkconfig file decides to throw it away.

@esp_sprite,

Thanks, it has been fixed.
