RE: BOOT_MODE

Hi,

I am not familiar with the terms "boot mode" or "boot pin", but it sounds to me like you just want to check if a GPIO is pressed during (power-on) reset, and make a decision based on that. This should be straight forward: Just configure a pin as GPIO input and read it in the start of your application (the pin must still be asserted when the application starts up in this case, but that should not be a problem). Then enter test mode where you accept UART commands and do the various tests you have implemented. The SDK does not have any single example that match your requirement, but you should find most of the pieces you need in the hardware peripheral examples.
