System Test and Initialization The PICO-EHL4 uses certain routines to perform testing and initialization during the boot up sequence. If an error, fatal or non-fatal, is encountered, the system will output a few short beeps or display an error message. The board can usually continue the boot up sequence with non-fatal errors.
AMI BIOS Setup The AMI BIOS ROM has a pre-installed Setup program that allows users to modify basic system configurations. These configurations are stored in the battery-backed CMOS RAM and BIOS NVRAM so the information is retained when power is turned off. To enter BIOS Setup, turn on the system and immediately press <Del>...

Introduction to Watchdog Timer This section details how to set up and program the Watchdog Timer for your AAEON system or board. The watchdog timer is used to automatically detect malfunctions and recover the system. During normal operation, the system will regularly send a signal to reset the watchdog timer.
C.2 Programing the Watchdog Timer with AAEON SDK If you have installed the AAEON Framework, you can program the Watchdog Timer using the AAEON SDK. Simply locate where the SDK is installed, and double click the icon. The following dialog box will appear: Count Mode: Set Watchdog Timer to count in minutes or seconds.
C.3 Programing Watchdog Timer with AAEON Windows EAPI AAEON Framework (KMDF Driver) must be installed before calling these functions. EapiLibInitialize() should be the first to call before calling other EAPI functions. EApiLibUnInitialize() should be called to release resources before program exit. When building C/C++ apps, Lib (Library, aaeonEAPI.lib) is needed.
EApiWDogStop must be called before Stage D/G to prevent system from being reset. C.3.1 Watchdog Timer Functions C.3.1.1 EapiWDogGetCap() Command Line: EApiWDogGetCap(…) __OUTOPT uint32_t *pMaxDelay, __OUTOPT uint32_t *pMaxEventTimeout, __OUTOPT uint32_t *pMaxResetTimeout Use this command to get maximum Supported Delay / Supported Event Timeout / Supported Reset Timeout of the watchdog timer.
C.3.1.2 EapiWDogStart() Command Line: EApiWDogStart( __IN uint32_t Delay, __IN uint32_t Minute, __IN uint32_t EventTimeout, __IN uint32_t ResetTimeout Use this command to start the Watchdog Timer and set the timeout values. To stop the Watchdog Timer, issue the command EApiWDogStop. After issuing EAPiWDogStop, the command EApiWDogStart must be called again with new values to restart.
C.3.1.3 EapiWDogTrigger() Command Line: EapiWDogTrigger() Use this command to trigger the Watchdog Timer. Parameters Function Parameters None Condition Return Values Library Uninitialized EAPI_STATUS_NOT_INITIALIZED Watchdog Not Started EAPI_STATUS_ERROR Common Error Common Error Code Others EAPI_STATUS_SUCCESS C.3.1.4 EapiWDogStop() Command Line: EapiWDogStop() Use this command to close the Watchdog Instance. This will disable the Watchdog Timer and clear previous settings.
C.3.1.5 EapiWDogReloadTimer() Command Line: EapiWDogReloadTimer() Use this command to reload the Timeout count Parameters Function Parameters None Condition Return Values Library Uninitialized EAPI_STATUS_NOT_INITIALIZED Common Error Common Error Code Others EAPI_STATUS_SUCCESS C.3.1.6 EapiWDogGetStatus() Command Line: EapiWDogGetStatus( __OUTOPT uint32_t *pwdtMinute, __OUTOPT uint32_t *pwdtCountTime, __OUTOPT uint32_t *pwdtReloadTime Use this command to get the Watchdog Timer mode, time count value and reload timer.
