| # FWU Metadata Configuration File |
| # |
| # Format: <device> <offset> <metadata_size> <erase_size> |
| # |
| # This file describes where the FWU metadata is stored. You can specify |
| # up to two entries for redundant metadata copies. |
| # |
| # Device: MTD device (/dev/mtdX), block device (/dev/mmcblkX), or file path |
| # Offset: Byte offset from start of device (hex with 0x prefix) |
| # Metadata Size: Size of metadata structure in bytes (hex with 0x prefix) |
| # Erase Size: Sector/erase block size (hex with 0x prefix, defaults to |
| # metadata_size, required only for MTD device) |
| # |
| # Examples: |
| # |
| # MTD devices (NOR/NAND flash): |
| # /dev/mtd0 0x0 0x1000 0x1000 |
| # /dev/mtd1 0x0 0x1000 0x1000 |
| # |
| # Block device (eMMC/SD): |
| # /dev/mmcblk0 0x100000 0x78 |
| # /dev/mmcblk0 0x101000 0x78 |
| # |
| # or: |
| # /dev/disk/by-partlabel/metadata1 0 0x78 |
| # /dev/disk/by-partlabel/metadata2 0 0x78 |
| # |
| # Regular file: |
| # /boot/fwu-mdata.bin 0x0 0x78 |
| # |
| # Default configuration (update for your platform): |
| /dev/mtd0 0x0 0x78 0x1000 |
| /dev/mtd1 0x0 0x78 0x1000 |
