Problems solved by technology

[0003] Multi-core SSD firmware generally has a data volume of several hundred KB or more. The system needs to provide a continuous memory area for storing SSD firmware information. The general method is to store it in SRAM (Static Random Access Memory, Static Random Access Memory) or DDR ( Double rate synchronous dynamic random access memory, Double Data Rate SDRAM), but because the SSD main control chip has to adapt to SSD products of various structures, but in order to control the development cost of SSD products, not all SSD products can provide large ISRAM Or the SSD memory area, which makes the current method of loading SSD firmware not fully applicable, which will increase the hardware cost of the SSD

Abstract

The present invention relates to a multi-core firmware loading method, device, computer equipment, and storage medium. The method includes acquiring SSD firmware and packet header information; splitting the SSD firmware to form several data packets; and handling the several data packets one by one. , to obtain the accumulated CRC value; judge whether the accumulated CRC value is consistent with the packet header information; if so, release the cores of the main control chip to run the SSD firmware; if not, return to obtain the SSD firmware and packet header information. The invention abandons the concept of unified processing and handling after the transmission of the serial port Xmodem protocol, realizes reducing the dependence on the hardware conditions of SSD development, and reduces the hardware development cost of SSD products.

Description

technical field [0001] The present invention relates to a solid-state hard disk, and more specifically refers to a multi-core firmware loading method, device, computer equipment and storage medium. Background technique [0002] At present, the process of loading the firmware of the SSD controller is as follows: figure 1 As shown, after the chip is powered on, the multi-core loading project is loaded by the code embedded in the microcontroller and used for the normal operation of the chip, and then the SSD (Solid State Drives, Solid State Drives) firmware is downloaded by the multi-core loading project through the Xmodem protocol of the serial port To a continuous memory area, parse out the packet header information and SSD firmware information in the SSD firmware package, after the CRC (Cyclic Redundancy Check, Cyclic Redundancy Check) check is correct, through the DMAC (Direct Memory Access Controller, The Access Controller) module transports the SSD firmware to the execut...
