Installed into the first 0x4000 sector of the eMMC storage's BCPKG2 partitions, "BootConfig" contains data used to configure TrustZone/OS behaviors.
BootConfig is normally all-zero for retail units, however TrustZone additionally sets the loaded configuration to all-zero when running on a retail unit anyway.
Format
Despite having 0x4000 for storage, the actual loaded BootConfig is only 0x640 bytes, with the following format:
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x200 | Unsigned Configuration |
| 0x200 | 0x100 | RSA-PSS Signature |
| 0x300 | 0x100 | Signed Configuration |
| 0x400 | 0x240 | Reserved |
