11 7.5 Running the USB 2.0 Demo (Zynq used as a USB device) From the SDK GUI, right-click on the zynq_mmp_usb_test software project and select Run As > Launch on Hardware (GDB) to load the USB test to the board and run it. You should see the following on the Tera Term terminal. Open Windows Explore to see the device being displayed as a Removable Disk. You might also see the following dialog box once you run the USB test. In this case click Cancel and go to the next step and continue. 10

12 Double-click on the Removable Disk in the Windows Explore. The PC prompts a message The disk in drive is not formatted. Do you want to format it now? This procedure will format a disk drive Make sure you are formatting the Zynq MMP USB Flash and not your PC s hard drive Verify the USB drive letter before formatting Avnet cannot take responsibility for lost data or damaged hard drives Click YES to format the device for the FAT file system. Once the formatting is complete, a new window opens with the Removable Disk directory path. Copy a file from any of the drives and paste it under the Removable Disk directory. Open the copied file from the Removable Disk directory and make modifications and save the file. Now, copy the file from the Removable Disk directory and paste it in any other directory. In the SDK GUI, if a Run session is currently running, click on the Red square to terminate the Run as shown in the following figure before running another test. 11

You should see the following on the Tera Term terminal. Open a command window and ping the board as shown below. If the Ethernet connection is working, you should see 4 replies back as shown. 14

16 To connect to the echo server, use the telnet utility program. Type the following telnet command as shown below and hit the return key. If the echo server works properly, any data sent to the board is echoed in response. Some telnet clients immediately send the character to the server and echo the received data back instead of waiting for the carriage return. Simply type a few characters and see them echoed back on the terminal. In the SDK GUI, if a Run session is currently running, click on the Red square to terminate the Run as shown in the following figure before running another test. 15

17 8 Booting from the microsd Card Prior to booting from the microsd card, the PS boot mode switch must be set for the SD Card Boot. Please set the boot mode switch (SW5, positions 1-5) on the MMP to Generating the microsd card boot image The microsd card image can be generated using the SDK tool or a batch file. For this example we will be using a batch file to generate the microsd card boot.bin image. The Peripheral Test, which we previously ran on the board using the JTAG port, will be used to generate the microsd card boot.bin image. Please go to the make_mcs_and_bin_files folder of the reference design and double-click on make_mcs_file.bat and make_bin_file.bat file to generate the microsd card boot.bin image as well as an MCS file (the MCS file will be used in the next section to boot from the QSPI device on the Zynq MMP). Note: The boot.bin and MCS files for the Peripheral Test design are already generated for you and are located in the ready_to_download folder of the reference design, should you have any issues with the boot.bin and MCS files generations using the above batch file. Copy the content of your microsd card to your hard drive so that you can restore the microsd card content that was shipped with your Zynq MMP. Delete the content of the microsd card. Use your PC to copy the make_mcs_and_bin_files\boot.bin file to the root directory of the microsd card. Make sure the board is powered down and the boot mode switch (SW5, positions 1-5) on the MMP is set to

18 Insert the microsd card into the microsd card socket located on the Zynq MMP under the USB connectors (please do not use the microsd card connector on the MMP baseboard for this reference design) and power up the board. The blue DONE LED will be illuminated and you should see the Peripheral Test results on the Tera Term terminal. 17

$In the following figure, use the browse button to set the Image File to the make_mcs_and_bin_files\zynq_mmp_peripheral_test.mcs file generated in the previous section.$

19 9 Booting from the QSPI Flash Prior to booting from the QSPI Flash, the QSPI device must be programmed using the SDK Flash programming utility. Power down the board and set the boot mode switch (SW5, positions 1-5) on the MMP to (Cascaded JTAG mode). Power up the board. Select Xilinx Tools > Program Flash from the SDK toolbar as shown in the following figure. In the following figure, use the browse button to set the Image File to the make_mcs_and_bin_files\zynq_mmp_peripheral_test.mcs file generated in the previous section. Set the Offset to 0, Flash Type to qspi_single, and click Program. It will take a few minutes to program the QSPI Flash on the Zynq MMP 7Z045 module (set the Flash Type to qspi_dual_parallel when using the Zynq MMP 7Z100 version). 18

Upon successful programming of the QSPI Flash, you should see the following in the SDK GUI. Note: The Zynq MMP QSPI Flash is programmed with the PCIe reference design when the MMP is shipped.

20 Upon successful programming of the QSPI Flash, you should see the following in the SDK GUI. Note: The Zynq MMP QSPI Flash is programmed with the PCIe reference design when the MMP is shipped. To restore the content of the QSPI Flash please download the PCIe MCS file from the PCIe reference design posted to the web site. Power down the MMP baseboard and set the boot mode switch (SW5, positions 1-5) on the MMP to (QSPI boot mode). Power up the board, the blue DONE LED will be illuminated and you should see the Peripheral Test results on the Tera Term terminal. 19
