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 update method and device for a solid-state hard disk controller, wherein the method includes the following steps: running the working code of the solid-state hard disk controller; judging whether the solid-state hard disk controller receives a handshake from a host computer within a preset waiting time frame; if not, then the solid-state hard disk controller work code loads the firmware loading program in the memory to run in the RAM, if so, the solid-state hard disk controller downloads the firmware programming program into the RAM. The present invention does not need to operate the GPIO of the controller to switch the operation mode of the controller, but uses the handshake frame instead, which can reduce the time for updating firmware and improve the efficiency of updating firmware.

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,...
