Reset Information#

Passing information when resetting into and out of the bootloader.

To signal the bootloader to run, the application needs to write the BootloaderResetCause_t structure to the first address of RAM, setting BootloaderResetCause_t::reason to BOOTLOADER_RESET_REASON_BOOTLOAD.

The reset cause is only valid if BootloaderResetCause_t::signature is set to BOOTLOADER_RESET_SIGNATURE_VALID.

BootloaderResetCause_t resetCause = {
  .reason = BOOTLOADER_RESET_REASON_BOOTLOAD,
  .signature = BOOTLOADER_RESET_SIGNATURE_VALID
} 

When the bootloader reboots back into the app, it sets the reset reason to BOOTLOADER_RESET_REASON_GO if the bootload succeeded, or BOOTLOADER_RESET_REASON_BADIMAGE if the bootload failed due to errors when parsing the upgrade image.

Note

• The reset information is automatically filled out before reset if the bootloader_rebootAndInstall function is called.
