State Indicator Macros#
The bootloader indicates which state it is in by calling these // macros. Map them to the ::halBootloadStateIndicator function // (in bootloder-gpio.c) if you want to display that bootloader state. // Used to blink the LED's or otherwise signal bootloader activity.
Finished init sequence, ready for bootload.
Called right before bootloader resets to application. Use to cleanup and reset GPIO's to leave node in known state for app start, if necessary.
Standalone bootloader polling serial/radio interface.
Processing download image.
Download process was a success.
Download process failed.
Enumerations#
Defines various bootloader states. Use in LED code to signal bootload activity.
Functions#
Initialize GPIO.
Helper function used for displaying bootloader state (for example: with LEDs).
Force activation of bootloader.
