Firmware

The following page details the generic firmware setup involved in getting started with a Beta release of Lumorphix.

Setup

Ensure you have completed the previous setup stages (see Hardware and PC) and fulfilled the software requirements as per Beta Release Info.

Binary

Select an appropriate (based on your target hardware and desired functionality) Lumorphix firmware binary from here.

Silicon

GOWIN

If your target hardware has GOWIN silicon, perform the following:

1. Configure the FPGA:

   1. If you are using Linux, via the following command:

      BASH

      $ openFPGALoader -b tangnano9k -f <Beta Release FPGA Firmware>.fs

   2. If on Windows, utilise the GOWIN programmer.

2. Verify the FPGA has been configured - you should notice the heartbeat LED is flashing.

3. Upload the Lumorphix Firmware

   1. Place the board into ‘Firmware Update’ mode - as detailed by the hardware-specific information that corresponds to your target hardware, for example here.

   2. Upload the corresponding Lumorphix Firmware via the following commands:

      1. If you are using Linux, (assuming no other USB devices connected - otherwise adjust ‘USB1’ accordingly) via the following commands:

         BASH

         $ sudo stty -F /dev/ttyUSB1 921600
         $ sudo python firmware-uploader.py <Beta Release CPU Firmware>.v /dev/ttyUSB1 921600

      2. If you are on Windows, determine which COM port the Tang Nano is connected to (via Device Manager), and use your Python IDE to run the following command (where <x> is the COM port number):

         CODE

         <IDE cmd prompt> firmware-uploader.py <Beta Release CPU Firmware>.v 'COM<x>' 921600

4. Reset the Lumorphix Flash region (as it will contain rubbish after the initial power on) via the ‘User button’ section on page Tang Nano 9k.

If you are planning to run the dual-core variant of Beta Release 02.0001 on the Tang Nano 9K you must perform the following steps:

1. Program the FPGA with the single-core variant of firmware

2. Upload the dual-core variant of CPU firmware

3. Program the FPGA with the dual-core variant of firmware

This is due to the fact that resource limitations prevent uploading CPU firmware with the single-core FPGA firmware.

AMD / Xilinx

If your target hardware has AMD / Xilinx silicon, perform the following:

1. Launch Vivado (or ML, Enterprise or Lab edition).

2. Open Hardware Manager

3. Select ‘Open Target’

4. Select ‘Add configuration memory device’

   1. Search and select the configuration memory part name listed in the corresponding child page of Hardware Targets.

   2. Select ‘OK’

   3. Navigate to the Lumorphix firmware binary in the ‘Configuration file’ selection field.

   4. Select ‘OK’

5. Once the flash programming has completed, power cycle or hard reset (again see the corresponding child page of Hardware Targets on how to perform a hard reset) the board.

6. You should notice a heartbeat LED that is flashing to indicate the hardware has been successfully configured.
