Detailed Description

Macro Definition Documentation

◆ IOT_RESET_SUCCESS

#define IOT_RESET_SUCCESS ( 0 )

Return values used by reset driverReset operation completed successfully.

◆ IOT_RESET_FUNCTION_NOT_SUPPORTED

#define IOT_RESET_FUNCTION_NOT_SUPPORTED ( 1 )

Reset function not supported.

◆ IOT_RESET_INVALID_VALUE

#define IOT_RESET_INVALID_VALUE ( 2 )

At least one parameter is invalid.

Enumeration Type Documentation

◆ IotResetReason_t

enum IotResetReason_t

Enumerator
eResetPowerOnBoot	Normal power on Boot, when the power is applied to the device.
eResetWarmBoot	Last reset triggered due to warm Reset. for ex: iot_reset_reboot(0) was called to reset the device
eResetColdBoot	Last reset triggered due to cold Reset. for ex: iot_reset_reboot(1)
eResetWatchdog	Last reset triggered due to watchdog expiration
eResetBusTimeout	Last reset triggered due to internal bus timeout on the SoC
eResetPmic	Last reset caused by power management IC
eResetBrownOut	Last reset caused by power brown out
eResetOther	Last reset caused by other reasons specific to the underlying hardware

◆ IotResetBootFlag_t

enum IotResetBootFlag_t

Enumerator
eResetWarmBootFlag	Perform warm-reset
eResetColdBootFlag	Perform cold-reset

Function Documentation

◆ iot_reset_reboot()

void iot_reset_reboot ( IotResetBootFlag_t xResetBootFlag )

iot_reset_reboot is used to reboot the device.

Parameters

[in] xResetBootFlag flag to determine either to do cold-reset or warm-reset. cold-reset means the device is restarted and does not keep any blocks of the SOC powered on i.e. device is shutdown and rebooted), and warm-reset means the device is restarted while keeping some of the SoC blocks powered on through the reboot process. For example warm-boot may keep the RAM contents valid after reset by keeping the power on for RAM banks, while cold-boot will wipe off the contents. One of the IotResetBootFlag_t value.

◆ iot_reset_shutdown()

int32_t iot_reset_shutdown ( )

iot_reset_shutdown is used to shutdown the device. If the target does not support shutdown of the device, IOT_RESET_FUNCTION_NOT_SUPPORTED is returned to the user.

Returns

does not return and device shutdown on success
IOT_RESET_FUNCTION_NOT_SUPPORTED if shutdown not supported.

◆ iot_get_reset_reason()

int32_t iot_get_reset_reason ( IotResetReason_t * xResetReason )

iot_get_reset_reason is used to get the last reset reason. If the underlying HW does not support the feature of persisting the reset reason, then this API will return IOT_RESET_FUNCTION_NOT_SUPPORTED error with the value in out as don't care.
