Push buttons and boot source selection:

The carrier board has two reset buttons:

Cold reset - SM1

Warm reset - SM3

Note: When working in QSPI mode, the reset push button does not work.

The carrier board has two boot selection jumpers:

BT SL 0 – Select SDIO device, selects between SD (open) and eMMC (closed)

BT SL 1 – Selects boot source between SD/eMMC (close) and QSPI NOR Flash(open)

Getting started

In order to operate the evaluation board follow the following steps:

Unpack the evaluation board

Connect the power supply to the power inlet

Connect the UART to USB cable to the Debug port (J-20)and open a terminal

application on the PC using the following parameters:

Rate - 115,200 Bps, data – 8 bits, party – none, stop – 1bit and flow control – none.

Note that the virtual com number may differ from PC to PC.

Connect an Ethernet network to the Ethernet port for network or WEB access.

Select the right boot source using BT SL 0 and 1 jumpers.

For activating the desktop application, a VGA module should be placed on J32(The

VGA is set to 768x1024), see picture below. USB mouse and keyboard can be

connected to J1 and/or J3.

For more details on the Shiratech Web site.

Note: The board is loaded with a demo version that uses the QSPI for preloader and boot,

while the file system is loaded on the internal eMMC chip. An image for SD card can be

downloaded from the Shiratech site.

Boot sources

The EVK has 3 possible boot sources:

1. QSPI NOR memory – a 128MB memory which include a minimal file system, via this

file system the internal eMMC disk can be format and updated with new versions.

2. eMMC – A 4GB eMMC memory, including a full demo version.

3. SD card – an SD card can be plugged into the evaluation board J74 on the (on the

lower side of the board) – not supplied with the board an image is available on the

Shiratech web site.

Byte blaster connectivity

The SOM include a connector for byte blaster. J1 can be connected to an external byte

blaster cable. In order for the byte blaster to work SW3 should be set to off

JTAG
