Introduction

This document provides the design information on the AM335x processor based Starter Kit (TMDSSK3358) to

users.

Description

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.

EVM System View

TMDSSK3358 is partitioned into two different boards: the main board (processor, peripherals & 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 10mm 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 the pictures provided below.

AM335xStarterKitHardwareUsersGuide 5 Clocks The main clock for the processor is derived from a 24MHz crystal. An on-board oscillator in the AM3358 generates the base clock and subsequent module clocks as needed within the AM3358 processor. A 32kHz clock for the RTC on the AM3358 is derived from a 32kHz crystal on board. 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.

AM335xStarterKitHardwareUsersGuide 7 Board Identity Memory The board contains a serial EEPROM with the board specific data which allows the processor to automatically detect which board is connected and the version of that board. Other hardware specific data can be stored in this memory as well. The part number of the memory device used is CAT24C256WI-GT3. See the Configuration/Setup section for details on the data in this memory.

AM335xStarterKitHardwareUsersGuide 8 • 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. See the Starter Kit Errata.
