    • In a method of burning a firmware to an embedded device, a booting file is firstly created and saved in the firmware. The booting file includes a boot loader, a first kernel, a second kernel, a first initrd, a second initrd of a firmware, a rootfs, and an application program. The method burns the boot loader, the first kernel, the second kernel, the first initrd, and the second initrd in a flash memory of the embedded device. When the rootfs and the application program are recorded in a storage system of the embedded device, the method downloads the rootfs and the application program from a storage system of the embedded device, and burns the rootfs and the application program to a register of the flash memory.
    • 在将固件刻录到嵌入式设备的方法中,首先创建引导文件并将其保存在固件中。 引导文件包括引导加载程序,第一内核,第二内核,第一initrd,固件的第二initrd,rootfs和应用程序。 该方法在嵌入式设备的闪存中刻录引导加载程序,第一个内核,第二个内核,第一个initrd和第二个initrd。 当rootfs和应用程序被记录在嵌入式设备的存储系统中时,该方法从嵌入式设备的存储系统下载rootfs和应用程序,并将rootfs和应用程序烧录到闪存的​​寄存器 记忆。

    • In a memory testing method for testing a memory module of a computing device, an operating voltage of the memory module is adjusted to a first voltage or a second voltage. A predetermined data set is written into the memory module after the operating voltage of the memory module is adjusted, and the written data set is read out from the memory module, to accomplish a data writing and reading process of the memory module. A register value that presents how many memory errors have occurred during the data writing and reading process is acquired from an ECC register of the memory module, to determine whether the memory module is stable during the adjusting of the operating voltage according to the register value.
    • 在用于测试计算设备的存储器模块的存储器测试方法中,将存储器模块的工作电压调节到第一电压或第二电压。 在调整存储器模块的工作电压之后,将预定的数据组写入存储器模块,并从存储器模块读出写入的数据组,以完成存储器模块的数据写入和读取过程。 在存储器模块的ECC寄存器中,从存储器模块的ECC寄存器获取寄存器值,该寄存器值表示数据写入和读取过程中发生了多少存储器错误,以根据寄存器值来确定存储器模块在工作电压的调整期间是否稳定。

    • The present invention relates to a valve, and a floating action type servo-valve used for fluid control, including a valve body, a torque motor, a pilot stage and a power stage control mechanism. An upper valve block, an intermediate block and a lower valve block are stacked and fastened by a fastener in the valve body. A torsion-bar spring of the torque motor passes through the center of an armature and is fixed to the valve body with a stand. A pilot stage revolving shaft and a power stage revolving stage are provided in a same central line, with a mating between the pilot stage revolving shaft and the upper valve block and a mating between the power stage revolving shaft and the lower valve block. The servo valve includes a shifting enlargement mechanism constitute by a shifting fork and a shifting lever.
