scripts

• generate bit wrapper bin file

  source /tools/Xilinx/Vivado/2019.1/settings64.sh
  cd petalinux/images/linux
  
  tee design_1_wrapper.bit.bif << EOF
  all:
  {
    ../../../project/project.runs/impl_1/design_1_wrapper.bit
  }
  EOF
  
  echo "all: { ../../../project/project.runs/impl_1/design_1_wrapper.bit }" design_1_wrapper.bit.bif
  
  bootgen -image design_1_wrapper.bit.bif -arch zynq -o ./design_1_wrapper.bit.bin -w
  

• flash bin to fpga

  BITSTREAM_NAME=design_1_wrapper.bit.bin
  cp /root/shared/$BITSTREAM_NAME /lib/firmware
  echo 0 > /sys/class/fpga_manager/fpga0/flags
  echo $BITSTREAM_NAME > /sys/class/fpga_manager/fpga0/firmware
