RISC-V + USB core demo
For the icebreaker, the hardware connections are :
P1B4: USB DPP1B3: USB DNP1B2: Pull up. Resistor of 1.5 kOhm to USB DP
To run :
Build and flash the bitstream
- This will build
fw/boot.hexand include it as the BRAM initial data
- This will build
Flash the main application code in SPI at offset 1M
make -C fw prog_fw
Connect to the iCEBreaker uart console (
ttyUSB1) with a 1M baudrate- and then at the
Command>prompt, pressrfor 'run'. This will start the USB detection and device should enumerate
- and then at the
