1. build and install ===================== $ make $ sudo make install

2. dnw tool usage ===================== Connect board to PC and open minicom. Boot board and enter U-Boot command line mode. Then run command "dnw " in U-Boot. U-Boot may print bellow message: Insert a OTG cable into the connector! OTG cable Connected! Now, Waiting for DNW to transmit data

Now, you can download your file to board by follow command on PC end: $ sudo dnw <file_to_download>

Note: If your board isn't FL Ok6410, please set right load-address via "a" option. Above steps have only download file to board's RAM, so you need flash it to nand via U-Boot command "nand write".

If above doesn't work, pls check if you can see bellow message in dmesg. usb 1-1: new full speed USB device using uhci_hcd and address 2 usb 1-1: configuration #1 chosen from 1 choice secbulk:secbulk probing... secbulk:bulk out endpoint found!
