Quick Setup #1 (Device Driver + DS21458 T1/E1)

• Select TCLK source for the DS21458 resource card. If this is the only DS33Z41 in the system (i.e. used in

loopback) then select TCLK=MCLK. From

Table 2, this requires that the J45.3+J45.4 jumper is not installed. If

this is the second DS33Z41 in the system select TCLK=RCLK, which requires that J45.3+J45.4 jumper is

installed. Note: The TCLK source settings can be changed using the driver interface, which is described

below.

• Complete the hardware configuration and one of the basic DS33Z41 configurations as described in the

previous section.

• At this point any packets sent to the DS33Z41 are sent out the T1/E1 ports. Incoming Ethernet packets should

cause the RX LED to blink, transmitted packets cause the TX LED should also blink.

• Launch ChipView.exe, select Register View

• To interact with the device driver go to ChipView and select from the drop down menu:

• Tools→Plugins→Load Plugins. When asked if DLLs have already registered select yes

• Select Tools→Plugins→DS33Z41/11/41 Device Driver Demo

• A new form called ‘Zchip Configuration’ appears

• Preload basic configuration for the GUI by selecting File→Load Settings (in the ‘Zchip Configuration’ form).

Select the file named ‘basic_Config.eset’

Quick Setup #2 (DS21458 T1/E1, Register Based)

1. Disable device drivers and callbacks – remove all jumpers from J45 header. Press the reset button, or cycle

power on the board to restore the system to its power-on state.

2. Configure the DS33Z41. After the definition files load, go to the File menu and select F

ile→Memory Config

File→L

oad .MFG file. When prompted, select the file named z41_basic.mfg.

3. Set the DS2148 serial card for IBO mode. Using the menu marked ‘D

ef File Selection’ switch to the

DS21458RC_FPGA def file. Set the register MO+CLK to 0x47.

4. Configure the DS21458. Go to the File menu and select F

ile→Register INI File→Load .INI file. When

prompted, select either the file named T1_IBO_ SourceTime.ini (TCLK=MCLK) or T1_IBO_ LoopTime.ini

(TCLK=RCLK). Set one board to be the source of network timing (TCLK=MCLK), and one board to follow the

timing source (TCLK=RCLK). The RLOS LEDs should go out when this step is complete for both boards.

5. Additional setup (for both boards):

• Switch to the DS33Z41 def file and set the following:

• Set the GL.IMUXCN register to 0x0F (both systems)

• Set GL.IMUXC register to 0x00 then to 0x82 (both systems)

• Check GL.IMUXSS register. They should be 0xFF on both systems

• Return to GL.IMUXCN and set the bits RXE and SENDE

• The system should now be configured to pass Ethernet traffic into one system and out of the other.

Configuration Note: Using a Single System

The DS33Z41 is intended for use in a system with a DS33Z41 at each end. However, the system may be tested

with only a single DS33Z41 system. This configuration requires that the DS21458 serial link is in loopback, either

internal loopback or hardware loopback may be used. In this configuration any packets sent to the Ethernet side

will be echoed back. In this configuration the setting for DS21458 TCLK=MCLK should be used (see

Table 2) and

steps intended for the “second” system may be ignored.

Configuration Note: A Mixing Device Driver and Register-Based Modes

Quick setup #1 discuses device driver based operation. Quick setup #2 discusses register based operation. To

some extent both modes may be used simultaneously to gain insight to device configuration. For example:

• In register view click “Read All” this causes all registers to be read, changed registers turn green.

• Switch to the device driver GUI, select one of the forms, make changes, and click “send configuration”

• Switch back to register view and click “Read All”. Newly changed registers will turn green, showing which

registers changed as a result of settings selected in the device driver GUI

A second type of device driver/register-based configuration is to power the board with the device drivers enabled,

and then remove the jumpers that enable the device drivers. This allows for a fast initial configuration.
