Description

GBL file specification.

Specification of the GBL file format. Each struct represents a valid GBL tag, and an GBL file contains a series of tags.

Data Structures

struct EblTagHeader_t
GBL tag header. Must be the first element in all GBL tags.
struct EblHeader_t
GBL header tag type.
struct EblApplication_t
GBL application tag type.
struct EblBootloader_t
GBL bootloader tag type.
struct EblSeUpgrade_t
GBL SE upgrade tag type.
struct EblMetadata_t
GBL metadata tag type.
struct EblProg_t
GBL flash program tag type.
struct EblEnd_t
GBL end tag type.
struct EblEncryptionHeader_t
GBL encryption header tag type.
struct EblEncryptionInitAesCcm_t
GBL encryption init tag type. Used with AES-CCM encryption.
struct EblEncryptionData_t
GBL encryption data tag type.
struct EblEncryptionAesCcmSignature_t
GBL encryption AES-CCM MAC tag type.
struct EblCertificateEcdsaP256_t
GBL certificate chain for signing.
struct EblSignatureEcdsaP256_t
GBL ECDSA secp256r1 signature tag type.
