ADSP-21569 EZ-Kit as A2B Main

This section describes the steps to run the demo using ADSP-21569 EZ-Kit as the A2B main platform. Note: Running this demo requires CrossCore Embedded Studio to be installed on the machine. For details, refer section 2.1.1

Setup

The hardware connections to be done are described below.

A2B Evaluation boards shall be connected in the following order

  1. ADZS-21569 EZ-KIT (Main) <–>EVAL-AD2428WC1BZ (Sub 0) <–> EVAL-AD2428WB1BZ (Sub 1) as shown in Figure 51
  2. Connect twisted-pair wire between the “B” connector on the Main board and the “A” connector on the Sub 0 board. Repeat the same connection between Sub 0 and Sub 1
  3. Connect 12V power supply to the power connector (P4) on ADZS-21569 EZ-KIT board.
  4. Attach an USBi cable to the main board connector P5 as shown in Figure 51. Other end of the cable should be connected to the PC
  5. Connect audio source (e.g., output from an iPod) to ‘Audio Line- in’ ports, shown in Figure 51, AD2428WB1BZ boards.
  6. Connect separate audio sinks (e.g., active speakers) to ‘Audio Line-out’ ports, shown in Figure 51, on ADZS-21569 EZ-KIT and AD2428WB1BZ boards.

Jumper settings for ADZS-21569 EZ-KIT

There are no additional jumper settings needed for the purpose of this demo. The jumper settings should be maintained as mentioned in the ADZS-21569 EZ-KIT manual default configuration.

Flashing target framework on ADZS-21569 EZ-KIT

The SS4G target framework must be flashed on the board to facilitate proper download of schematic. This can be done as follows:

  1. Ensure that the “Boot Mode” switch is set to 0 on the ADZS-21569 EZ-KIT board.
  2. Connect the JTAG (ICE 1000 or ICE 2000) and power on the board.
  3. The batch script to flash the .ldr file is given as part of the SigmaStudio+ installer. It can be found in «A2B plugin for SigmaStudio+ installation path»\Target\Utility\
  4. Run Flash_LDR.bat
  5. Once the flashing is complete, change the boot mode to 1 and reset the board. The framework is now ready for download from SigmaStudio+

Running sample Demo

The following steps describe the procedure to run a sample demo in PC mode

  1. Open A2B schematic from («A2B plugin for SigmaStudio+ installation path»\Schematics\PC\adi_a2b_ADSP21569Demo.ssprj).
  2. Flash the SigmaStudio target framework on ADSP-21569 following steps in section 5.1.1.2
  3. Make sure that USBi cable is connected to ADSP-21569 EZ-KIT board as shown in Figure 51 and the board is powered on.
  4. Make sure that .xml files are provided for programming codecs on sub A2B evaluation boards as described in step 2 in section 4.1.3
  5. Select the schematic DXE for ADSP 21569 processor by going to the SharcXICore Settings as shown in Figure. The DXE can be found at - «A2B plugin for SigmaStudio+ installation path»\Target\LDR\SS_App_Core1.dxe
  6. Click on “LinkCompileDownload” icon in SigmaStudio+. This will start the discovery and configuration of A2B nodes and peripheral devices as per the schematic.
  7. After successful discovery and initialization audio routing can be observed as per the sample demo configuration shown in Figure 44.
  8. In order to change the audio routing, modify the audio schematic under Sharc core of ADSP-21569 EZ-KIT platform. The default routing is as shown in the Figure 55

Note: For creation of .dxe file with different settings, refer to Appendix D.
