of 1-bit failures). The available memory configuration can be either 1 GB, 2 GB or 4 GB.
2.2.2 Flash Memory
2.2.2.1 SPI Boot Flash
The COMe-cP2020 provides two 2 MB SPI boot flashes for two separate U-Boot images, a standard SPI boot flash and a
recovery SPI boot flash. The fail-over mechanism for the U-Boot recovery can be controlled via the DIP switch SW1, switch
1. Refer to Chapter 6.10 for further information.
The SPI boot flashes include a hardware write protection option. If write protection is enabled, writing to the SPI boot
flashes is not possible.
N O T I C E
19
The U-Boot code and settings are stored in the SPI boot flashes. Changes made to the U-Boot settings are available only in the currently selected SPI boot flash. Thus, switching over to the other
SPI boot flash may result in operation with different U-Boot code and settings.

data storage (optional).
2.2.2.5 SDHC Socket
The COMe-cP2020 is provided with a microSDHC card socket, J1, which accepts microSD and microSDHC cards up to 32 GB. If
used, the card must be installed prior to installation of the COMe-cP2020 in a system.
If the SDHC interface is routed to the COM Express connector (via DIP switch SW1, switch [1]), the onboard socket J1 cannot
be used.
2.2.3 System/User Data EEPROMs
The COMe-cP2020 provides two 64-kBit EEPROMs, one for system data storage and one which is free for user data storage.
The user data EEPROM is accessible via the OS or an application. The system data EEPROM is reserved for system usage.
2.3 Timer
The COMe-cP2020 is equipped with the following timer:
• Real-Time Clock (RTC)
The COMe-cP2020 is equipped with an onboard high-precision real-time clock RV-8564-C3. The RV-8564-C3 RTC is registercompatible with the PCF8564A RTC from Philips/NXP. In addition, it provides a very tight frequency tolerance at low power
consumption. The COMe-cP2020 does not include a 3 V lithium battery or a GoldCap power source for RTC backup. Power for
the RTC is supplied by the carrier via the VCC_RTC pin.
2.4 Watchdog Timer
The COMe-cP2020 provides a Watchdog timer that is programmable for a timeout period ranging from 125 ms to 4096 s in
16 steps. Failure to trigger the Watchdog timer in time results in a interrupt or a system reset or both. In dual-stage mode,
it results in a combination of both interrupt and reset if the Watchdog is not serviced. A hardware status flag will be provided to determine if the Watchdog timer generated the reset. Refer to the Watchdog Timer Control Register (WTIM) in
Chapter 3 for further information.
There are four possible modes of operation involving the Watchdog timer:
• Timer only mode
• Reset mode
• Interrupt mode
• Dual stage mode
At power on the Watchdog is not enabled. If required, the bits of the Watchdog Timer Control Register must be set according
to the application requirements. To operate the Watchdog, the mode and time period required must first be set and then
the Watchdog enabled. Once enabled, the Watchdog can only be disabled or the mode changed by powering down and then
up again. To prevent a Watchdog timeout, the Watchdog must be retriggered before timing out. This is done by writing a ‘1’
to the WTR bit. In the event a Watchdog timeout does occur, the WTE bit is set to ‘1’. What transpires after this depends on
the mode selected.
20
www.kontron.com
COMe-P2020 User Guide
The four operational Watchdog timer modes can be configured by the WMD[1:0] bits, and are described as follows:
Timer only mode - In this mode the Watchdog is enabled using the required timeout period. Normally, the Watchdog is
retriggered by writing a ‘1’ to the WTR bit. In the event a timeout occurs, the WTE bit is set to ‘1’. This bit can then be polled
by the application and handled accordingly. To continue using the Watchdog, write a ‘1’ to the WTE bit, and then retrigger
the Watchdog using WTR. The WTE bit retains its setting as long as no power down-up is done. Therefore, this bit may be
used to verify the status of the Watchdog.
Reset mode - This mode is used to force a hard reset in the event of a Watchdog timeout. In addition, the WTE bit is not reset
by the hard reset, which makes it available if necessary to determine the status of the Watchdog prior to the reset.
Interrupt mode - This mode causes the generation of an interrupt in the event of a Watchdog timeout. The interrupt handling is a function of the application. If required, the WTE bit can be used to determine if a Watchdog timeout has occurred.
Dual stage mode - This is a complex mode where in the event of a timeout two things occur: 1) an interrupt is generated,
and 2) the Watchdog is retriggered automatically. In the event a second timeout occurs following the first timeout, a hard
reset will be generated. The second timeout period is the same as the first. If the Watchdog is retriggered normally as specified above, operation continues. The interrupt generated at the first timeout is available to the application to handle the
first timeout if required. As with all of the other modes, the WTE bit is available for application use.
Pin B27 on the COM Express® J1 connector offers a signal that can be asserted when a Watchdog timer has not been triggered within time. It can be configured to any of the 2 stages. Deassertion of the signal is automatically done after reset. If
deassertion during runtime is necessary please contact Kontron for further assistance.
