Research on UFS Firmware Optimization Method

In order to solve the problem of slow data transmission in large capacity storage media UFS in vehicle domain controllers, this paper proposes a firmware optimization method that improves code execution efficiency and saves code execution time by regrouping firmware level codes; At the same time, by storing the optimal voltage in the chip, the time to find the optimal voltage is reduced. The experimental results indicate that the data transmission speed of UFS is significantly improved during low-temperature shock starting.
