watchdog_enable_caused_reboot() function
Did watchdog_enable cause the last reboot? Perform additional checking along with watchdog_caused_reboot to determine if a watchdog timeout initiated by watchdog_enable caused the last reboot. This method checks for a special value in watchdog scratch register 4 placed there by watchdog_enable. This would not be present if a watchdog reset is initiated by watchdog_reboot or by the RP-series microcontroller bootrom (e.g. dragging a UF2 onto the RPI-RP2 drive).
Syntax
bool watchdog_enable_caused_reboot(void);
Implemented in ![]()
watchdog.c:123
Return value
true If the watchdog timer or a watchdog force caused (see watchdog_caused_reboot) the last reboot and the watchdog reboot happened after watchdog_enable was called false If there has been no watchdog reboot since the last power on reset, or the watchdog reboot was not caused by a watchdog timeout after watchdog_enable was called. A power on reset is typically caused by a power cycle or the run pin (reset button) being toggled.
