2.2. SD card filesystem layout

If you are using the recovery images or following the Linaro software release instructions, you do not need to change any of the firmware or configuration files.

The V2M-Juno motherboard firmware images, SoC software images, and settings are stored on an SD card on the board. At boot time, the V2M-Juno motherboard firmware accesses the SD card and copies certain images into internal flash memory.

The SD card is exposed to a host computer as a USB mass storage device with a FAT16 filesystem. A brief description of the filesystem layout follows.

|-- MB           - Motherboard firmware (BIOS, IOFPGA image, PMIC configuration)
|-- SITE1        - Configuration files for the Juno SoC
|   |--HBI0262B  - Configuration files for Juno r0 only|    `--HBI0262C - Configuration files for Juno r1 only
|-- SITE2        - Supporting files for LogicTile daughterboards
|-- SOFTWARE     - SoC software images (SCP Firmware, ARM Trusted Firmware,
|                  UEFI, Linux, etc)
`-- config.txt   - Configuration file for the V2M-Juno motherboard

See Connecting to a host computer for instructions on how to connect the V2M-Juno motherboard and access the SD card filesystem.
