Problems solved by technology

This method is simple and effective. However, once the controller product is in the mass production stage, the solid-state hard disk hardware circuit board usually does not lead to the relevant GPIO pins. If you update the firmware, you have to operate the GPIO, which will consume a lot of time and efficiency. low

Abstract

The invention discloses a firmware updating method and a firmware updating device for a solid state disk controller. The method comprises the following steps of: operating a working code of the solidstate disk controller; Judging whether the solid state disk controller receives a handshake frame of the upper computer or not within a preset waiting time; If not, the solid state disk controller working code loads the firmware loading program in the memory to run in the RAM, and if yes, the solid state disk controller downloads the firmware programming program to the RAM. According to the method, the operating mode of the controller does not need to be switched by operating a GPIO (General Purpose Input / Output) of the controller, and a handshake frame mode is used instead, so that the firmware updating time can be reduced, and the firmware updating efficiency is improved.

Description

technical field [0001] The invention relates to a solid-state hard disk, more specifically to a method and device for updating firmware of a solid-state hard disk controller. Background technique [0002] The current method of updating the firmware of the controller is as follows: figure 1 shown. If the controller needs to update the firmware, first configure the Bootrom (controller working code) to be in forced download mode by changing the input voltage value of the external GPIO pin of the controller, then power on the chip, the Bootrom inside the chip will run, and the Bootrom will pass the control Download Mploader (firmware programming program) to the RAM space inside the chip through the interface specified by the device, and then Bootrom jumps the running pointer to the location specified by RAM to execute MPloader. Mploader will re-initialize the system hardware, download the firmware from the interface specified by the controller to the RAM space inside the chip,...
