4.3.9 FS Programming

Table 4-11 lists the FS Programming command.

Table 4-11 FS Programming
Description
Brief This command is used for programming a single chunk of a complete image.
Opcode 0x34
Direction Host to target
Response Ack + 4 bytes status code
Format [USHORT] Length (exclude checksum)
[BYTE] Checksum (exclude length)
[BYTE] Opcode
[UINT16] key size
[UINT16] chunk size
[UINT32] flags
[key buffer in bytes] key buffer
[chunk buffer in bytes] chunk buffer
Comments The status code indicates the accumulated number of bytes received.
The status for the last chunk must be 0 to indicate successful programming, otherwise, a negative status is returned.
Chunks must be serially activated as the NWP assumes orderliness.
Chunk size must be the minimum between 4096 and the residue left from the complete image.
Flags are for future use and must be 0.
If an image is encrypted, a 16-byte key is required.
