Abstract

The invention discloses a firmware hot update method and device, a chip, a medium and a program product, and belongs to the field of chips. The firmware comprises a first segment of firmware and a second segment of firmware, the first segment of firmware is used for loading the second segment of firmware, and the second segment of firmware is used for realizing a configuration function of the firmware; the method comprises the following steps: in response to a power-on operation, running a first segment of firmware; the first section of firmware is used for loading the second section of firmware so as to run the second section of firmware; in response to the firmware upgrading instruction, overwriting the second segment of firmware into the updated second segment of firmware; the updated address of the second segment of firmware is the same as the address of the second segment of firmware; in response to the update instruction, re-operating the first segment of firmware; and loading the updated second section of firmware through the first section of firmware, and running the updated second section of firmware. According to the scheme, the hot update of the firmware in the chip can be realized under the condition that the Boot ROM does not exist in the chip.
