• Example Directory: arm_blink_leds
  • The LEDs blink via ARM memory.
  • GPMC has been used between ARM and FPGA for memory Transfer
cd examples/arm_blink_leds

# If the fpga tools present on BBB

# Else scp the .bin file in Beaglewire/examples/arm_blink_leds
# In host computer go to Beaglewire/examples/arm_blink_leds
# make
# Command to send it to FPGA: 
# scp arm_blink.bin debian@

# Loading SPI flash after FPGA reset, it will be boot up on SPI.
make load_spi

# Reset the FPGA for running bitsream (RST Button on BeagleWire)
  • Before running the arm blink script ensure that bridge libs are compiled.
    cd Beaglewire/bridge_lib/
  • Once the bridge libs are compiled:
    cd Beaglewire/examples/arm_blink_leds
    chmod +x arm_blink.sh
    sudo ./arm_blink.sh
