Arm Blink LEDs

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

Flash the FPGA with arm_blink bitstream

cd examples/arm_blink_leds

# If the fpga tools present on BBB
make

# 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@192.168.6.2:/home/debian/Beaglewire/examples/arm_blink_leds

# 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)

Running arm blink script for transferring the memory words from ARM to FPGA (LEDs)

• Before running the arm blink script ensure that bridge libs are compiled.

  cd Beaglewire/bridge_lib/
  make
  

• Once the bridge libs are compiled:

  cd Beaglewire/examples/arm_blink_leds
  chmod +x arm_blink.sh
  sudo ./arm_blink.sh
  

TO DO

• Generalize C code with the help of memmap
