This program is Free Software and has ABSOLUTELY NO WARRANTY please tell me why ? thank you very much i had do this :press AUX and then press Power on, release AUX after 1s. Found DFU Runtime: [0x1457:0x5119] devnum=0, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade" i can download file to NEO both (NAND)uboot and (NOR)uboot. the (NAND)uboot just have one menu "boot". but when i execute “dfu-util -a kernel -R -D ./uImage*** ”. it is also can work. i thank just neo(no other device even  a USB mouse) connect to HOST that dfu-util can work. Xiangfu, for DFU mode you need to stop at the u-boot menu. On gta02, if you boot via NOR (press AUX key before pressing power-on), you will always stop at the boot menu. The NAND u-boot behavior depends on the environment settings, I don't know how you can manually make it stop. Maybe you just have to be quick? GTA01 don't know... Wolfgang GTA01 and GTA02 : to stop NAND u-boot menu should press AUX key and press POWER key and hold both all them until the screen show the menu.
