| 2 | =========================================== |
| 3 | |
| 4 | The FLASH Image System (FIS) directory is a flash description |
| 5 | format closely associated with the RedBoot boot loader. |
| 6 | |
| 7 | It uses one single flash eraseblock in the flash to store an index of |
| 8 | all images in the flash. |
| 9 | |
| 10 | This block size will vary depending on flash but is typically |
| 11 | 32 KB in size. |
| 12 | |
| 13 | Required properties: |
| 14 | - compatible : (required) must be "redboot-fis" |
| 15 | - fis-index-block : (required) a index to the eraseblock containing |
| 16 | the FIS directory on this device. On a flash memory with 32KB |
| 17 | eraseblocks, 0 means the first eraseblock at 0x00000000, 1 means the |
| 18 | second eraseblock at 0x00008000 and so on. |
| 19 | |
| 20 | Example: |
| 21 | |
| 22 | flash@0 { |
| 23 | partitions { |
| 24 | compatible = "redboot-fis"; |
| 25 | fis-index-block = <0>; |
| 26 | }; |
| 27 | }; |
