Overview of configuration files and microSD card directory structure
Because the V2M-Juno r2 motherboard configuration microSD card is non-volatile flash memory, it is
only necessary to load new configuration files if you change the system configuration. The configuration
microSD card contains default configuration files.
If you connect a workstation to the configuration USB port or configuration Ethernet port, the
configuration memory device, that is, the configuration microSD card, appears as a
USB Mass Storage
Device
(USBMSD) and you can add, edit, or delete files.
You can use a standard text editor that produces DOS line endings to read and edit the board
configuration files.
The following figure shows a typical example of the directory structure in the microSD card memory.
Caution
Files names and directory names are in 8.3 format:
• File names that you generate must be in lower case.
• Directory names must be in upper case.
• All configuration files must end in DOS line endings,
