3.2.1Reset Switch
The MVME2502 has a single push button switch that has both the abort and the reset
functions. Pressing the switch for less than three seconds generates an abort interrupt if there
is firmware that will read the GPIO2 (0xffdf0095) interrupt register. U-boot does not
implement any interrupts and also does not detect the interrupt or display anything when the
button is pressed.
Holding it down for more than three seconds will generate a hard reset. The VME SYSRESET is
generated if the MVME2502 is the VMEbus system controller.
3.3LEDs
The MVME2502 utilize light emitting diodes (LEDs) to provide a visible status indicator on the
front panel. These LEDs show power failures, power up states, Ethernet link/speed, Ethernet
activity, SATA link and activity and PCIe valid lane status. There are few user configurable LEDs.
Each LED description is necessary for troubleshooting and debugging.

MVME2502 Installation and Use (6806800R96E)
Page 93
4.4.2P2020 Internal Timer
The processor's internal timer is composed of eight global timers divided into two groups of
four timers each. Each timer has four individual configuration registers and they cannot be
cascaded together.
4.4.3Watchdog Timer
The on-board CPLD provides programmable 16-bit watchdog timers. It has a 1 ms resolution
and generates a board reset when the counter expires. Interrupt is generated to the processor
when this occurs. Default value is 60 seconds.
4.4.4CPLD Tick Timer
The MVME2502 supports three independent 32-bit timers that are implemented on the CPLD
to provide fully programmable registers for the timers.
Functional Description
4.5Ethernet Interfaces
The MVME2502 has three eTSEC controllers. Each one supports RGMII, GMII, and SGMII
interface to the external PHY. All controllers can only be utilized when using the RGMII
interface. Using the GMII allows only up to two usable controllers.
MVME2502 provides two 10/100/1000 Ethernet interfaces on the front panel and another two
are routed to the RTM through the backplane connector. Due to controller limitations, one
controller is designed to be routed to the front panel or to the RTM. This setting is possible by
using a third party gigabit Ethernet LAN switch with a single enable switch such as PERICOM’s
P13L301D. The routing direction is configured through the on-board dip switch.
The registers of the PHY are accessed through the processor’s two-wire Ethernet management
interface.The front panel RJ45 connector has integrated speed and activity status indicator
LEDs. Isolation transformers are provided on the board for each port.

Page 94
Functional Description
4.6SPI Bus Interface
The enhanced serial peripheral interface (eSPI) allows the device to exchange data with
peripheral devices such as EEPROMs, RTC, Flash and the like. The eSPI is a full-duplex
synchronous, character-oriented channel that supports a simple interface such as receive,
transmit, clock and chip selects. The eSPI receiver and transmitter each have a FIFO of 32 Bytes.
The P2020 supports up to four chip selects and RapidS full clock cycle operation. It can operate
both full-duplex and half duplex. It works with a range from 4-bit to 16-bit data characters and
is a single-master environment. The MVME2502 is configured such that the eSPI can operate
up to 200 MHz clock rate and can support booting process.The firmware boot flash resides in
the P2020 eSPI bus interface.
4.6.1SPI Flash Memory
The MVME2502 has two 8 MB on-board serial flash. Both contain the ENV variables and the UBoot firmware image, which is about 513 KB in size. Both SPI flash contain the same
programming for firmware redundancy and crisis recovery. The SPI flash is programmed
through the JTAG interface or through an on-board SPI flash programming header.
For information on U-boot and ENV Variables location see, Flash Memory Map, Table 5-2 on
page 112.
4.6.2SPI Flash Programming
The MVME2502 has three headers: a 10-pin header for SPI Flash programming, an 80-pin
header for the JTAG connectivity, and a 20-pin JTAG header for ASSET hardware connectivity.
The following options are used to program the on-board flash:
Using on-board SPI header - The MVME2502 uses the 10-pin header with a Dual SPI Flash
in-circuit programming configuration. The pin connection is compatible with DediProg
SPI Universal Pin Header.
Using 60-pin external JTAG header - An external JTAG board with a JTAG multiplexer is
compatible with the MVME2502 and is attached using an external cable. It is used to
update the boot loader in the field. Using this method, programming is done through the
JTAG interface or by using the dedicated SPI Flash programming header on the JTAG board.
94
MVME2502 Installation and Use (6806800R96E)
Page 95
Factory Pre-Programming - Programming the SPI Flash usually takes a while. Ideally, the
SPI Flash should be pre-programmed in the factory before shipment.
ICT Programming - This programming is done on exposed test points using a bed of nails
tester.
The board power should be switched on before programming. The switch S2-8 should also be
powered on to successfully detect the SPI Flash chip.
4.6.3Firmware Redundancy
The MVME2502 utilizes two physically separate boot devices to provide boot firmware
redundancy. Although the P2020 provides four SPI Bus chip selects, the P2020 is only capable
of booting from the SPI Device controlled by chip select 0. External SPI multiplexing logic is
implemented on the MVME2502 to accommodate this chipset limitation.
Functional Description

Functional Description
The MVME2502 CPLD controls the chip select to SPI devices A and B. The CPLD chip select
control is based on the Switch Bank (S2-2).
Figure 4-2SPI Device Multiplexing Logic

On power-up, the selection of the SPI boot device is strictly based upon the Switch Bank (S2-2)
setting. Depending on the S2-2 setting, SPI_SEL0 is routed to one of two SPI devices. The
selected SPI device must contain a boot image. Once the boot image is copied into memory
and executed, the CPLD will wait, and once the P2020 will write on one bit of the CPLD
watchdog register, the CPLD will then pass through the SPI chip select from the P2020 to SPI
device chip selects. Now the software can perform read/write processes on any SPI device,
including copying from one SPI device to another.
With this flexible approach to firmware redundancy, one should always be able to recover from
a corrupt active firmware image, as long as a healthy firmware image is maintained in single
bootable SPI Device.
The MVME2502 supports automatic switch over. If booting one device is not successful, the
watchdog will trigger the board reset and it will automatically boot on the other device.

4.6.4Crisis Recovery
The MVME2502 provides an independent boot firmware recovery mechanism for the
operating system. The firmware recovery can be performed without leaving the firmware
environment.
During crisis recovery, the healthy boot image contained in SPI Device B is copied to SPI Device
A, replacing the corrupt boot image contained in SPI Device A.
Crisis recovery is performed as follows:
1.Power off the board.
2.Set Switch S2-2 to "ON" to point to SPI Device B (crisis image).
3.Power on the board.
4.Press <h> key on the keyboard to go to the U-Boot prompt.
5.Type "moninit fru" to copy the crisis image to SPI Device A.
Functional Description
6.Once the U-Boot prompt is visible, power off the board.
7.Set the S2-2 back to "OFF" to point to the SPI Device A.
8.Power on the board to boot from the newly recovered image on the SPI Device A.
The board will automatically switch over if one of the devices is corrupted.
4.7Front UART Control
The MVME2502 utilizes one of the two UART functions provided in the male micro-mini DB-9
front panel. A male-to-male micro-mini DB-9 to DB9 adapter cable is available under Artesyn
Part Number SERIAL-MINI-D (30-W2400E01A) and is approximately 12 inches in length.
Only 115200 bps and 9600 bps are supported. The default baud rate on the front panel serial
is 9600 kbps.

4.8Rear UART Control
The MVME2502 utilizes the Exar ST16C554 quad UART (QUART) to provide four asynchronous
serial interface’ to the RTM. These devices feature 16 bytes of transmit and receive first-in firstout (FIFO) with selectable receive FIFO trigger levels and data rates of up to 1.5 Mbps. Each
UART has a set of registers that provide the user with operating status and control. The QUART
are 8-bit devices connected to the processor through the local bus controller using LBC chipset
CS1, CS2, CS3 and CS4.
These four serial interfaces are routed to P2 I/O for RTM accessibility. There are total of five
serial ports available on the MVME2502 board.
4.9PMC/XMC Sites
The MVME2502 hosts two PMC/XMC sites and accepts either a PMC or an XMC add-on card.
Only an XMC or a PMC may be populated at any given time as both occupy the same physical
space on the PCB. The MVME2502 does not support combination PMC/XMC cards. The site
provides a rear PMC I/O.
98
The PMC sites are fully compliant with the following:
1.VITA 39 –PCI-X for PMC.
2.VITA 35-2000 for PMC P4 to VME P2 Connection.
3.PCI Rev 2.2 for PCI Local Bus Specification.
4.PCI-X PT 2.0 for PCI-X Protocol Addendum to the PCI Local Bus Specs.
5.IEEE Standard P1386-2001 for Standard for Common Mezzanine Card Family.
6.IEEE Standard P1386.1-2001 for Standard Physical and Environmental Layer for PCI
Mezzanine Card.
7.VITA 42 for XMC.
8.VITA 42.3, PCIe for XMC.
PMC/XMC sites are keyed for 3.3V PMC signaling. The PMC and the XMC add-on cards must
have a hole in the 3.3 V PMC keying position in order to be populated on the MVME2502 board.
The XMC specification accommodates this since it is expected that carrier cards will host both
XMC and PMC capable add-on cards.
MVME2502 Installation and Use (6806800R96E)
Page 99
The MVME2502 have a keying pin at the 3.3V location at each PMC site. The MVME2502 boards
are not 5 volt PMC IO compatible. The MVME2502 also has a 5 volt keying pin location at each
PMC site. At PMC site 2, the 5 volt keying pin hole is used to mount the SATA adapter card.
Warning label covers 5 volt keying pin at PMC site 1 and also at PMC site 2. If 5 volt PMC or XMC
devices are operated on MVME2502 it may cause damage to the board.
The MVME2502 utilizes the P2020 x2 link PCI Express interface for PMC/XMC1 and x1 link PCI
Express interface for PMC/XMC2. It is designed such that same PCI Express interface is used for
either PMC or XMC. It is made possible by using PCIe Mux/DeMux chip. The CPLD via on-board
switch controls the enable pin.
The CPLD controls the PCIe Mux/DeMux at both sites. The CPLD detects the presence signal
provided by the XMC or PMC board and it will be used to configure the routing of PCIe
Mux/DeMux correspondingly.
4.9.1PMC Add-on Card
Functional Description
The MVME2502 PMC interface utilizes IDT’s TSI384 as the PCie/PCI-X bridge. It supports up to
8.5 Gbps (64 bits x 133 Mhz). The on-board switch S2-5 configures the TSI384 to run on either
100 Mhz or 133 Mhz, with 133 Mhz as default.
The MVME2502 supports multi-function PMCs and processor PMCs (PrPMCs). The PMC site
has two IDSELs, two REQ/GNT pairs, and EREADY to support PrPMC as defined by VITA39.
4.9.2XMC Add-on Card
The x2 links the PCI-E Gen 1 and is directly routed to the P15 XM connector through Pericom
MUX Switch. The on-board switch S2-4 should be set to "ON".
The XMC add-on cards are required to operate at +5V or +12V (from carrier to XMC). The
MVME2502 provides +5V to the XMC VPWR (Variable Power) pins. The MVME2502 does not
provide +12V to the XMC VPWR pins. Voltage tolerances for VPWR and all carrier supplied
voltage (+3.3 V, +12 V, -12 V) are defined by the base XMC standard.

with the SATAMNKIT, which contains the following: one SSD/HDD, one SATA board, screws,
and a mounting guide. The SATA connector supports a horizontal mounted SSD/HDD.
The MVME2502 uses Marvell's 88SE9125 SATA controller and supports up to 1.5 Gbps, 3.0
Gbps, or 6.0 Gbps (SATA Gen 1). For status indicators, it has an on-board green LED, D12 and
D13 for SATA link, and SATA activity status respectively.
4.11VME Support
The MVME2502 operates in either System Controller (SCON) mode or non-SCON mode, as
determined by the switch setting of S1-1 and S1-2.
The P2020 x1 link is used for the VME backplane connectivity through the Tsi384 (PCI-E/PCI-X)
and Tsi148 (PCI-X/VMEBus) bridges.
See VMEBus P1 Connector, on page 64 and VMEBus P2 Connector, on page 66 for more
information.
4.11.1Tsi148 VME Controller
The VMEbus interface for the MVME2502 is provided by the Tsi148 VMEbus controller. The
Tsi148 provides the required VME, VME extensions, and 2eSST functions. TI
SN74VMEH22501transceivers are used to buffer the VME signals between the Tsi148 and the
VME backplane. Refer to the Tsi148 user's manual for additional details and/or programming
information.
4.12USB
The MVME2502 processor implements a dual-role (DR) USB 2.0 compliant serial interface
engine. DC power to the front panel USB port is supplied using a USB power switch which
provides soft-start, current limiting, over current detection, and power enable for port 1.
