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.

The Functional block diagram of the TMDSSK3358 design is shown below. Figure 4: TMDSSK3358 Block Diagram Processor The AM3358ZCZ processor is the central processor for TMDSSK3358.
  • Page 5 AM335xStarterKitHardwareUsersGuide 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.

The PHY address for the EMAC1-PHY and EMAC2-PHY are 00100 and 00101 respectively.The interrupts from the both PHYs are connected to both the Non Maskable Interrupt pin and to the processor GPIO pins. The Wake On LAN interrupts from the both PHYs are connected to the EXT_WAKEUP signal of the processor as an option.
