Bootloader GPIO definitions.
Enumerations |
|
| enum |
blState_e
{
BL_ST_UP , BL_ST_DOWN , BL_ST_POLLING_LOOP , BL_ST_DOWNLOAD_LOOP , BL_ST_DOWNLOAD_FAILURE , BL_ST_DOWNLOAD_SUCCESS } |
|
Defines various bootloader states. Use in LED code to signal bootload activity.
|
|
Functions |
|
| void | bootloadGpioInit (void) |
|
Initialize GPIO.
|
|
| void | bootloadStateIndicator (enum blState_e state) |
|
Helper function used for displaying bootloader state (for example: with LEDs).
|
|
| bool | bootloadForceActivation (void) |
|
Force activation of bootloader.
|
|
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. |
|
| #define | BL_STATE_UP () do { bootloadStateIndicator ( BL_ST_UP ); } while (0) |
|
Finished init sequence, ready for bootload.
|
|
| #define | BL_STATE_DOWN () do { bootloadStateIndicator ( BL_ST_DOWN ); } while (0) |
|
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.
|
|
| #define | BL_STATE_POLLING_LOOP () do { bootloadStateIndicator ( BL_ST_POLLING_LOOP ); } while (0) |
|
Standalone bootloader polling serial/radio interface.
|
|
| #define | BL_STATE_DOWNLOAD_LOOP () do { bootloadStateIndicator ( BL_ST_DOWNLOAD_LOOP ); } while (0) |
|
Processing download image.
|
|
| #define | BL_STATE_DOWNLOAD_SUCCESS () do { bootloadStateIndicator ( BL_ST_DOWNLOAD_SUCCESS ); } while (0) |
|
Download process was a success.
|
|
| #define | BL_STATE_DOWNLOAD_FAILURE () do { bootloadStateIndicator ( BL_ST_DOWNLOAD_FAILURE ); } while (0) |
|
Download process failed.
