Getting Started Guide
Configuring a Bitfile
This guide will take you through the process necessary to configure the Programmable Logic (PL) side of the Zynq Ultrascale+ MPSoC from the Processor Side (PS).
The following are requirements for this guide:
- ECM1900
- BRK1900
- microSD card
- USB type C storage device. Type converting adapter can be used
- USB type C to Host USB type cable
The following instructions show how to configure a bitfile:
- Unplug USB cable from Host PC.
- Insert the microSD card containing the BRK1900 Linux image into the microSD card slot on the ECM1900.
- Power the BRK1900 either through the DC barrel jack or the 6-pin Mini-Fin connector. Please read and follow the voltage and current specifications located under ‘Powering the BRK1900’ at BRK1900 Breakout Board.
- Plug in a USB type C cable from the UART port on the ECM1900 to the USB port of your host computer.
- Use your favorite serial console on your host computer to communicate with the COM port your USB device is connected to. The baud rate for this connection is 115200.
- Power cycle the BRK1900 to receive console output though the serial connection.
- After boot completes you can log in using using the credentials below:
- Username: root
- Password: root
- Generate a compatible bitfile for the ECM1900 (instructions shown below). You may also use our provided LED-ECM1900.bit which lights up the LEDs as 11000011.
- Place the bitfile onto a USB type C storage device.
- Plug the storage device into either the USB 3.0 type C port on the BRK1900, or the USB 2.0 type C port on the ECM1900.
- The storage device will mount to /run/media/sda1. Run the following command to configure the bitfile onto the PL side.
fpgautil -b /run/media/sda1/LED-ECM1900.bit
Creating a Compatible Bitfile
Required resources:
This guide will take you through generating a compatible bitfile for the ECM1900/BRK1900. Each bitfile generated for the ECM1900/BRK1900 will need the Zynq Ultrascale+ MPSoC IP instantiated within it. This IP will need to be configured with our included preset configuration TCL preset.
- Open a new Vivado design which targets the FPGA chip on your ECM1900
- Create a new block design in the IP Integrator (IPI)
- Instantiate the Zynq UltraScale+ MPSoC IP within the IPI
- Open the Zynq UltraScale+ MPSoC IP configuration GUI
- Click “Presets”
- Click “Apply Configuration”
- Select our provided Zynq UltraScale+ MPSoC IP Preset TCL file
- Click “OK” in the configuration wizard to save this configuration
- Select ‘Generate Block Design’ to generate the Verilog HDL sources
- Right click on the generated block design and select “Create HDL Wrapper”
- Instantiate the HDL Wrapper into your top level HDL module
- Add additional PL resources to your HDL design as required
- Generate the BRK1900 bitfile
- Configure the bitfile to the ECM/BRK1900 using the instructions provided above in ‘Configuring a Bitfile’
