Verification method and system

A verification method for verifying a content of a first volatile read-write memory of a chip, wherein a first non-volatile read-write memory of the chip stores a firmware image, the firmware image includes a predetermined calculation value, the chip includes a second volatile read-write memory, and the verification method comprises:

• verifying the firmware image of the first non-volatile read-write memory at a bootloader mode;
• loading a first portion of the firmware image into the first volatile read-write memory, and loading a second portion of the firmware image into the second volatile read-write memory;
• performing a first specific operation according to the first portion loaded into the first volatile read-write memory and the second portion loaded into the second volatile read-write memory to obtain a first calculation value;
• when the first calculation value matches with the predetermined calculation value, storing the first calculation value in the second volatile read-write memory and entering an active mode.

A system, comprises:

• a first volatile read-write memory;
• and
• a first non-volatile read-write memory, configured to store a firmware image, wherein the firmware image includes a predetermined calculation value;
• a chip, coupled to the first volatile read-write memory and the first non-volatile read-write memory, the chip including:
• a second volatile read-write memory;
• a verification program memory, configured to store a verification program;
• a processor, configured to perform a verification method for verifying a content of the first volatile read-write memory according to the verification program, the verification method including:
• verifying the firmware image of the first non-volatile read-write memory at a bootloader mode;
• loading a first portion of the firmware image into the first volatile read-write memory and loading a second portion of the firmware image into the second volatile read-write memory;
• performing a first specific operation according to the first portion loaded into the first volatile read-write memory and the second portion loaded into the second volatile read-write memory to obtain a first calculation value;
• when the first calculation value matches with the predetermined calculation value, performing a second specific operation according to the first calculation value to obtain a second calculation value;
• and
• storing the second calculation value in the second volatile read-write memory and entering an active mode.
