Colibri VF50, Colibri VF61 and Colibri iMX7 use a common raw Nand flash to store OS, configuration and user data.
The flash device is organized as follows:
The following flash layout describes the allocation of flash memory in the default configuration for Windows CE. Notes are inserted where the user can influence the flash layout.
| First page# (first block#) | size | Description |
|---|---|---|
| 0 (Block 0) | 2 kB | FCB factory data |
| 1 (Block 0) | 2 kB | Static config block |
| 2 (Block 0) | 2 kB | Bad block table |
| 3 (Block 0) | 122 kB | unused |
| 64 (Block 1) | 512 kB | Bootloader |
| 320 (Block 5) | 128 kB | Config block |
| 384 (Block 6) | 64752 kB1 | Registry, OS image and splash screen.2 |
| 32768 (Block 512) 3 | (total flash size) - 64 MB3 | Data used for user. Mounted as \FlashDisk on WinCE |
The size of the section for registry, OS and splash screen can be modified through the configblock setting part.nonfssize.
The actual size is: ((part.nonfssize * 1024) - 784) kB ↩︎
The location of OS / Registry / Splashscreen inside this section depends on the order of flashing. These three parts can even be interleaved. ↩︎
Starting position and size are affected by the configblock setting part.nonfssize.
The starting location is page (part.nonfssize * 512) (block part.nonfssize * 8).
The size is (total flash size in MB) - part.nonfssize MB. ↩︎
