1 Q extended data needs to be written into Three DGI: A001, 8020,9020

1.1 A001 extended application configuration

DGI	Length	Value (example)
A001	7 * N	15 01 00 00 FF 00 00 Data is organized in 7 bytes as a unit. Each unit corresponds to the configuration information of an extended application file. The parsing is as follows: 1-byte extended application file SFI; 1-byte file type: 01 indicates a variable-length record file, 02 indicates the cyclic record file; 1-byte Read permission: 00 indicates Read using the Read CAPP Cache command 1-byte write permission: 00 indicates Update using the Update CAPP Cache command 1-byte maximum length of a single record: Limit the maximum length of records that can be used 2-byte file size configuration: for variable-length record files, 2 bytes indicates the default file size, 00 indicates the size is not limited; for cyclic record files, it is the number of 1-byte records and the size of 1-byte records. You can adjust the DGI data domains based on the actual number of application files to be used and the actual SFI. The number and order of units consisting of 7 bytes determine the number and order of keys activated in the subsequent 8020 data domains. They must correspond one to one.

 

1.2 8020 subkey activation for extended applications

The composition and sequence of DGI data are as follows. The key sequence matches the SFI sequence of files defined in A001 and is set as the activation key of each file.

DGI	Len	Value
8020	10 * N	0x13 file extension application enable protection key (16 bytes) 0x14 file extension application enable protection key (16 bytes) ..........

1.3 9020: key verification value enabled for extended applications

DGI data is composed of the following data. The Checksum value (KCV) is composed of 8 bytes of each key pair in 8020 and 3 bytes left after encryption. The Checksum key order must be the same as that in 8020.

DGI	Len	Value
9020	03 * N	0x13 file Compound Application enable protection key verification value (3 bytes) 0x14 file Compound Application enable protection key verification value (3 bytes) .......

3 (READ extended application data) command DATACAPP READ

CPURESET () 00A4040008A00000033301010180B400A8020570 // read 0X15 and convert it into a file. The 0570 record 00B201F400 // read the 0X1E circular file, the first record

DNF can be used to buy extensions. QP will initialize two extensions.
After you buy it, you won't initialize it, but after you switch the skill, your tp qp has never been added.
