Zephyr usbserial driver on Qomu

This sample demonstrates how to load bitstream on EOS-S3 FPGA and use the usbserial driver.

Requirements

• Zephyr RTOS with printk enabled

• QuickLogic Qomu board

Building

west build -b qomu samples/boards/quicklogic/qomu

Flashing

To load example into Qomu you can use TinyFPGA-Programmer-Application.

python3 /PATH/TO/BASE/DIR/TinyFPGA-Programmer-Application/tinyfpga-programmer-gui.py --mode m4 --m4app build/zephyr/zephyr.bin --reset

See Qomu User Guide on how to load an image to the board.

Running

After connecting to the shell console you should see the following output:
