# Key features
 - The real cross platform. Linux, Windows, MacOS(not test yet)
 - Multi devices program support
 - Daemon mode support
 - Few depedencies (only libusb, zlibc, libbz2)
 - Firmware (uboot/kernel) uses WCID to auto load the winusb driver on the Windows side. Windows7 users need to install the winusb driver from https://zadig.akeo.ie/  Windows10 will install the driver automatically.

# Examples:
```
  uuu u-boot.imx            Download u-boot.imx via HID device

  uuu list.uu               Run all the commands in list.uu

  uuu -s                    Enter shell mode. Input command.

  uuu -v u-boot.imx         verbose mode

  uuu -d u-boot.imx         Once it detects the attachement of a known device, download boot.imx.

                            u-boot.imx can be replaced, new file will be download once board reset.

                            Do not unplug the SD card, write to the SD card, nor plug in a SD card when debugging uboot.

  uuu -b emmc u-boot.imx    write u-boot.imx to emmc boot partition. u-boot.imx need enable fastboot

  uuu -b emmc_all u-boot.imx sdcard.bz2\*
                            decompress sdcard.bz2 file and download the whole image into emmc
```
