BeagleWire

Installation

Ideally this quick start guide image would work, but it doesn't seem to have a working link to the SD card image. Instead this is what I've tried to get it working.

System setup

• fpga_load requires a newer kernel than the 4.9.82 in debian stretch. Instructions: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Kernel_Upgrade

  cd /opt/scripts/tools/
  git pull
  sudo ./update_kernel.sh --lts-4_14
  sudo reboot
  

• apt update hangs forever? sudo ifconfig usb0 mtu 1400

• Once it is back up, checkout the BeagleWire tree:

  git clone https://github.com/pmezydlo/BeagleWire
  

• Need to install kernel headers for building out-of-tree modules:

  sudo apt install linux-headers-$(uname -r)
  

• Need to build the FPGA manager module since the default kernel doesn't have it.

git clone --depth 1 -b 4.14 git://github.com/beagleboard/linux.git linux-4.14
cd linux-4.14
cp /boot/config-4.14.50-ti-r55 .config
patch -p1 <<EOF

• On some BBB it is necessary to boot while holding down the S2 button.
