Partition layout¶
In your board definition (board.hints) you need to define a kind of partition table. Here you give ranges in flash memory predefined names.
ZRouter expects to find these geom_map names:
| kernel | start address could be where bootloader ends, end address can be detected automatically if you define a searchkey |
| rootfs | start address could be where kernel ends, so you can usually use the same searchkey as before |
| config | size depends on flash size, e.g. 0x00200000 bytes (2MB) |
| upgrade | use start from 'kernel' and end from 'rootfs', so these partitions are covered at once |
This geom_maps have to be defined by every board itself, because the boards use different areas in flash to store bootloader and data for wireless initialization.
