Desktop application for programming TinyFPGA boards. Updated to python3 and to support QuickLogic's QuickFeather.

Note: This repository uses sub-modules for some of the functionality. Using the "Download ZIP" functionality does not package these necessary sub-modules. To use this project, please follow the instatllation instructions given below.

1. Clone the repository and install the tinyfpgab dependency

   git clone --recursive https://github.com/QuickLogic-Corp/TinyFPGA-Programmer-Application.git
   pip3 install tinyfpgab
   

2. Connect the QuickFeather board, and set it to flash mode.

   To put it into flash mode, press the RST button, and the LED should turn blue and start flashing.

   Press the USR button within 5 seconds of pressing the RST button. The LED will turn green and go into breathing mode.

   At this point, run lsusb on the terminal.

   lsusb should contain an entry similar to the following:

   Bus 002 Device 029: ID 1d50:6140 OpenMoko, Inc.
   

   or

   Bus 002 Device 029: ID 1d50:6130 OpenMoko, Inc.
   

   If the OpenMoko device is not present, then run the following commands.

   pip3 install apio
   apio drivers --serial-enable
   

   You should see:

   Serial drivers enabled
   Unplug and reconnect your board
   

   and then check the output of lsusb contains an entry as shown above.
3. It is recommended to set up an alias to simplify programming using the editor of your choice to edit ~/.bashrc:

   Change /PATH/TO/BASE/DIR/ to wherever you cloned this git repo.

   alias qfprog="python3 /PATH/TO/BASE/DIR/TinyFPGA-Programmer-Application/tinyfpga-programmer-gui.py"
   source ~/.bashrc
   

NOTE

Help is available by running with the --help parameter:

python3 tinyfpga-programmer-gui --help

or, if you have already setup the alias

qfprog --help

usage: tinyfpga-programmer-gui.py [-h] --mode [fpga-m4] [--m4app app.bin]
                                [--appfpga appfpga.bin]

The programmer allows you to specify various options:

• The --port port-name option is used to tell the programmer which serial port the QuickFeather board is connected to. The form of port-name varies depending on the system:

  COM## on PC/Windows

  /dev/ttyS## on PC/wsl1/Ubuntu18+ (where the ## is the same as the COM## shown by device manager under Windows)

  /dev/ttyACM# on PC/Ubuntu18+

  
  
• The --mode [operating-mode] tells the programmer to set the "operating mode" for the bootloader to use.

  The options currently supported are: --mode m4, --mode fpga, --mode fpga-m4

  This is used to let the bootloader identify the use case, and load the images accordingly.

  If --mode m4 : then the bootloader will only load the m4app binary that has been flashed

  If --mode fpga : then the bootloader will only program the fpga using the appfpga binary that has been flashed

  If --mode fpga-m4 : then the bootloader will program the fpga using the appfpga binary and then load the m4app binary that has been flashed

  NOTE 1. The bootloader needs to be updated first before flashing any appfpga or m4app images!

  Example:

  qfprog --port /dev/ttyX --bootloader /path/to/latest/qorc-sdk/qf_bootloader.bin --mode m4

  If not, then the --mode option has no effect, and it always acts as if --mode m4 is specified.

  NOTE 2. The --mode argument is mandatory and must be always specified.

• The --m4app app.bin tells the programmer to program the file app.bin as the m4 application

• The --appfpga appfpga.bin tells the programmer to program the file appfpga.bin as the application fpga binary

• The --reset option tells the programmer to reset the board, which will result in the bootloader being restarted, and if the user button is not pressed, the bootloader will then laod and start the most recent m4app.

  Example:

  qfprog --port /dev/ttyS8 --m4app output/bin/qf_helloworldsw.bin --reset --mode m4

  will program the m4app with qf_helloworldsw and then run it

• The --crc option simply prints the crc values for each of binaries that are programmed into the flash memory

• The --checkrev option compares the crc for a binary specified as an option to the binary file progammed into the flash

  Example:

  qfprog --port /dev/ttyS8 --m4app output/bin/qf_helloworldsw.bin --checkrev --mode m4

  will compare the crc for file output/bin/qf_helloworldsw.bin with the crc for the binary programmed into the m4app location of the flash memory

• The --update option causes the progammer to check the crc of any specified binary against the crc of the binary progammed into the flash, and only programmer the specified binary if it the crc is different

Danger Zone

• The --bootloader boot.bin option tells the programmer to program the file boot.bin as the bootloader application.

  If the programming fails for any reason, or the boot.bin file doesn't work as expected the QuickFeather will become non-functional and only recoverable by using J-LINK.

  
  
• The --bootfpga fpga.bin option tells the programmer to program the file fpga.bin as the fpga image for the bootloader.

  If the programming fails for any reason, or the fpga.bin file doesn't work as expected the QuickFeather will become non-functional and only recoverable by using J-LINK.

  
  
• The --mfgpkg mfgpkg/ option can be used to update all of the QuickFeather firmware or restore it to the factory delivered state.

  The programmer expects the mfgpkg/ directory will contain qf_bootloader.bin, qf_bootfpga.bin and qf_helloworldsw.bin.

  The recommended update method is to use the --update option with the --mfgpkg option

  
  

The 5 bin files are:

• bootloader
• bootfpga
• m4app
• appfpga
• appffe (for future use)
