AM335x Starter Kit Hardware
1 Introduction
The AM335x Starter Kit (TMDSSK3358) can be used as an evaluation and development platform for low
cost AM335x based solutions and networking platforms. The embedded emulation logic allows emulation
and debug using standard development tools such as TI’s Code Composer Studio by just using the
supplied USB cable. It is not intended for use in end products. All of the design information is freely
available and can be used as the basis for the development of an AM335x-based product.
2 EVM System View
TMDSSK3358 is partitioned into two different boards: the main board (processor, peripherals and the main
power supply) and the LCD Carrier board (LCD and touch screen). The TMDSSK3358 main board and the
LCD carrier board mounted are mounted together using 10 mm standoffs. The TMDSSK3358 main board
has dimensions of 5.257” x 2.798 “and that of the LCD Carrier board is 4.963” x 2.798 “. The top and the
bottom side views of the TMDSSK3358 are shown in Figure 1.

3 Functional Block Diagram
This section describes about the major functional blocks of the TMDSSK3358. The functional block
diagram of the TMDSSK3358 design is shown in Figure 4.
Figure 4. TMDSSK3358 Block Diagram
3.1 Processor
The AM3358ZCZ processor is the central processor for TMDSSK3358. All the resources on the board
surround the AM3358 processor to provide development capabilities for hardware and software. See the
AM3358 datasheet and TRM for the details about the processor.
There are system configuration signals, SYSBOOT, that can be set on the EVM to define some startup
parameters on the AM335x processor. Fore more details, see Section 3.6.
3.2 Clocks
The main clock for the processor is derived from a 24 MHz crystal. An on-board oscillator in the AM3358
generates the base clock and subsequent module clocks as needed within the AM3358 processor. A 32
kHz clock for the RTC on the AM3358 is derived from a 32 kHz crystal on board.

AM335x Starter Kit Hardware
3.3 Reset Signals
Power On Reset to the AM335x is driven by the PMIC. SYS_ WARMRESETn is a signal running to
several peripherals and AM335x which performs a reset on those peripherals. SYS_WARMRESETn is
asserted by a pushbutton on the main board and is used to force a reset of the AM335x. AM335x can also
pull down on the RESET_INOUTn signal to cause the SYS_ WARMRESETn line to go active. The
RTC_PORZ reset signal for the RTC section is derived using AND Gates.
3.4 Power
The power input to TMDSSK3358 is from a 5V Power Supply. This 5 V power is provided as power input
to the Power Manager TPS65910A3. The power requirements of the processor are taken care of by the
Power Manager IC TPS65910A3. The Power ON LED "D5" is ON if the PMIC output power VAUX33 is
available (to indicate the active status of the PMIC). The power sequencing requirements of the AM335X
processor are handled automatically by the TPS65910A3 PMIC. For more information, see AM335x
Sitara™ Processors Data Sheet.
NOTE: When powering the TMDSSK3358 EVM, always use the supplied power supply (CUI/V-
Infinity Part Number EMSA050300-P6P-SZ, Model 3A-182WP05) or equivalent model having
output voltage of +5VDC and output current max 3.0 Amps. A power supply is not included
with the kit.
3.5 Power Management IC
TMDSSK3358 uses the TPS65910A3 power management IC. The I2C0 on AM335x is used to control the
TPS65910A PMIC.
The PWRON input of PMIC is connected to an external push-button. The built-in debouncing time defines
a minimum button press duration that is required for button press detection. Any button press duration
which is lower than this value is ignored, considered an accidental touch.
For AM335x, the following power supplies from the TPS65910A are used.

3.8 Ethernet
TMDSSK3358 has two Giga bit Ethernet transceivers. AR8031-AL1A from Atheros is used as a single
port, tri speed PHY. A single 3.3 V is enough to power this PHY and the other voltages required were
generated internally. Reset for both the chips are driven by the SYS_WARMRESETn signal through a
SN74LVC1G07 buffer. Both the PHYs have individual 25 MHz, 50 ppm crystal as their clock source. The
25 MHz Clock out of the EMAC1-PHY port has been connected to the XTLI of the EMAC2-PHY as an
optional clock input.
NOTE: The Starter Kit EVM PCB does not support external delay for the clock signals on the RGMII
interface. The AR8031A PHY can be setup to use internal clock delay mode once booting is
complete. Therefore, there may be problems in function/performance when booting in Gb
mode or when running Gb Ethernet Mode before the AR8031A PHY is configured properly.
For more information, see Appendix A.

Table 12. Summary of Instructions
Title ...................................................................................................................................... Page
Advisory 2.2.1 RGMII Ethernet Operation —...................................................................................... 14
Advisory 2.2.2 Oscillator Power Supply Decoupling Capacitor —........................................................... 14
Advisory 2.2.3 CLKOUT Used as Source Clock —............................................................................... 14
Advisory 2.2.1 RGMII Ethernet Operation
Revision(s) Affected: 1.2B/1.2C
Details While the AM335x Starter Kit EVM has 2 Gb Ethernet PHY’s, AR8031A’s, on the board,
the PCB was designed to use internal clock delay mode of the RGMII interface and the
AM335x does not support the internal clock delay mode. Therefore, if operating the
Ethernet in Gb mode, there may be problems with the performance/function due to this.
The AR8031A PHY supports internal delay mode. This can be enabled by software to
guarantee Gb operation. However, this cannot be done to enable internal delay mode for
Ethernet booting.
Workaround Enable the internal clock delay mode in the AR8031A PHY using software after boot
occurs.
Advisory 2.2.2 Oscillator Power Supply Decoupling Capacitor
Revision(s) Affected 1.2B/1.2C
Details The AM335x Starter Kit EVM has a decoupling capacitor that is connected to the
oscillator power supply on the board. This capacitor is connected to the incorrect ground.
Instead of GND_OSC0 (local crystal ground), it should be connected to the main power
ground DGND.
Workaround Remove capacitor C95 and replace it so that it is connected to VDDS_OSC and DGND.
Advisory 2.2.3 CLKOUT Used as Source Clock
Revision(s) Affected 1.2B/1.2C
Details The AM335x GP EVM uses a CLKOUT1 signal from the AM335x device to source the
input clock for the audio CODEC. The CLKOUT signals from the AM335x should not be
used for input clock sources that have stringent jitter requirements.
Workaround Remove resistor R1528 on the board and connect an external 12MHz clock oscillator as
an input to U37.
