The section offsets are relative to a base, which is typically 0x80000000 pointing to the base of DRAM. | The section offsets are relative to a base, which is typically 0x80000000 pointing to the base of DRAM. | ||
Before being decrypted, the encrypted header's CTR additionally encodes metadata used to validate package2's contents as follows: | |||
* Size of the entire package2 with the raw header = ctr_word2 ^ ctr_word3 ^ ctr_word0 | |||
* Metadata version field = ((ctr_word1 ^ (ctr_word1 >> 16)) & 0xFF) ^ (ctr_word1 >> 24) | |||
In [4.0.0], the metadata version field must be less or equal to 4. | |||
