Driver Installation
The Virtual File System driver is distributed on the Euresys website download area: www.euresys.com > DOWNLOAD. The first time access requires a profile creation and select a user ID and a password.
The installation script creates 8 devices in the /dev directory.
The entries for Picolo U4 H.264 PCI-104 boards are named U4H264PCI104_0 to U4H264PCI104_7.
The presence of these files does not indicate that the corresponding board is installed in the system. Refer to Testing Your Board for details
Note that the number of created device files is independent of the number of boards present in the system.
Inserting/Removing the Virtual File System Driver
The Virtual File System driver is inserted automatically during the boot procedure of the Linux system.
You can use the rmmod command to remove the Virtual File System driver.
Mounting the File System
The following steps mount the first device detected as /mnt/my_board folder.
- Type the root password, $su (*)
- Create a device folder. This folder name can be freely chosen by the user, for instance #mkdir /mnt/my_board
- Mount the U4H264PCI104 device, #mount -t U4H264PCI104VFS/dev/U4H264PCI104_0/mnt/my_board
Note that all devices must be individually mounted after each PC boot.
(*) Some Linux distribution may not support the su command, alternatively sudo command can be used for each command requiring the root privileges (denoted with a # prompt). If none of these commands are available, refer to your distribution documentation for executing commands with the root privileges.
Unmounting the File System
You can use the Unmount command to unmount the file system, for instance #unmount/mnt/my_board
When un-mounting a Virtual File System:
- The default configuration settings are applied to all the objects.
- All the acquisitions in progress are stopped.
