Build FCS Server

FCS Server supports build for ARM64 (since HPS is ARM based) and x86 for testing purpose.

Related components

Build for x86

To build x86 version, g++ compiler is needed. Run:

make x86

optionally:

make test

Build for aarch64

To build ARM64 executable on the Linux x86, AArch64 toolchain is needed. E.g. on Ubuntu 18, install:

apt-get install g++-aarch64-linux-gnu

Run:

make aarch64

Build for All architectures

To build for both architectures, run:

make all

Output files in "out" directory:

  1. fcsServer.x86
  2. fcsServer.aarch64
  3. fcsServer where fcsServer is a copy of fcsServer.aarch64

Build with DEBUG symbols and NO security protections

make DEBUG=1 all

Running FCS Server on HPS (Yocto linux)

After building FCS Server, copy following files to HPS running Yocto OS to one folder:

  • fcsServer - executable
  • fcsServer.service - service unit file used by systemd
  • install.sh - install script

To change default log level (Info) or default port (50001), edit fcsServer.service file:

ExecStart=/usr/sbin/fcsServer [PORT_NUMBER] [LOG_LEVEL]

Possible log levels: Debug, Info, Error, Fatal

To install FCS Server, run install.sh within the folder script is located, with root privileges. FCS Server will automatically start and will persist after system reboot.

SYSTEMCTL commands:

  • Checking FCS Server status

    systemctl status fcsServer

  • Start/stop FCS Server

    systemctl start fcsServer
systemctl stop fcsServer

  • Restart FCS Server

    systemctl restart fcsServer

  • Changing FCS Server settings after installation: edit service unit file /etc/systemd/system/fcsServer.service, reload systemd manager configuration

    systemctl daemon-reload

    and restart service

    systemctl restart fcsServer

  • You can test FCS Server by sending a command using the files in FCSFilter/test/testfiles

    netcat [ FCS Server IP address ] [ FCS Server port] < ./get_chip_id.bin
e.g. netcat localhost 50001 < ./get_chip_id.bin

Logs

To view FCS Server logs, run journalctl:

journalctl -u fcsServer
