Configuration files
Configuration files in the configuration microSD card control the board powerup and configuration
process.

Overview of configuration files and microSD card directory structure
Because the N1 SDP 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 DBG USB port, the 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 lowercase.
• Directory names must be in uppercase.
• All configuration files must end in DOS line endings,

The directory structure and file name format ensure that each image is matched to the correct target
device defined in the N1 SDP configuration EEPROM.
