Flashing the Arduino HID

This operation can be done using your RPi. Here the common steps:

  1. Disconnect the RESET wire from the Arduino board.
  2. Connect the Arduino and RPi with a suitable USB cable.
  3. Log in to the Raspberry Pi using SSH (ssh root@<addr> with password root by default) or using keyboard and monitor. The Raspberry Pi obtains the network address over DHCP.
  4. Upload the firmware (USB keyboard & mouse is used by default, on this step you can choose PS/2 keyboard): 
    [root@pikvm ~]# rw
[root@pikvm ~]# systemctl stop kvmd
[root@pikvm ~]# cp -r /usr/share/kvmd/hid ~
[root@pikvm ~]# cd ~/hid
[root@pikvm hid]# make
[root@pikvm hid]# make install
[root@pikvm hid]# reboot
  5. Connect the RESET wire, disconnect the USB cable, and reboot the RPi.

On make install you may encounter the following error:

/root/.platformio/packages/tool-avrdude/avrdude: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

Create a symlink for this library:

[root@pikvm ~]# ln -s /usr/lib/libtinfo.so.6 /usr/lib/libtinfo.so.5

And run make install again.
