Note:
LOCK1- R56 is not mounted on the OMAP processor module by default
and hence NAND lock functionality is disabled.
POP_INT03- Resistor R56 is NOT mounted on the OMAP processor
module by default and hence this signal (INT) is not connected to
GPMC_nCS2/GPIO_53.
DDR_TEMP_SENSE2- Resistor R2 is not mounted on the OMAP processor
module by default and hence DDR temp sense is disabled.
If the user wants to enable the feature, corresponding resistors need to
be mounted.

Board Components
2. OMAP 35x EVM System
This chapter describes the operation of the major components on the OMAP35x
EVM.
OMAP35x EVM system consists of
•EVM Main board
•Processor Module
•Power Module
2.1 EVM Main Board
The EVM Main Board provides the peripheral interfaces and connectors for the
system along with Processor board and Power Module. In the OMAP35x EVM
architecture, the Processor Module connector pin outs and functions are defined
by the Main Board. The following sections describe about the various interfaces on
the EVM main board.
2.1.1 LCD and Touch Screen
The EVM has a dual mode LCD module LS037V7DW01 from Sharp and is
interfaced to the Display subsystem (DSS) of OMAP3530. The LCD panel supports
18-bit RGB format.
The QVGA/VGA selection (LCD_QVGA/nVGA) and LCD power (LCD_EnVDD) can be
controlled through software using the GPIO signals. Refer GPIO Tables above.
The EVM supports Touch-screen using 4 wire resistive touch screen controller
TSC2046. The primary interface between the touch-screen controller and the
processor is McSPI1 interface. The TSC2046 also has the ability to interrupt the
processor via the TS_nPEN_IRQ signal.
The TSC2046 is powered from the LCD_3v3 voltage rail, the same as the one that
powers the LCD panel.
