You can manually copy the files in the u disk install directory to /mnt/nand1-1/ to complete the installation.

I ask for help. When I upgraded the firmware, something went wrong. I tried to copy the files to / mnt / nand1-1 / to complete the installation, but the software was not updated. And I made a fatal mistake and removed them from the folder and turned off the power. Now with USB also does not read. Is there a way to fix this?

Hello. How did you solve the DDCSV update problem? I have the same problem.
Is it necessary to connect to the serial port? What is the voltage and speed of the serial port?
Where to download 2016-02-09 installation package? DDCSV upload via serial port or usb drive? In zip frome facebook all files in folder "install(2016-02-09)", do I need to rename to "install"?

At the end of the system startup phase, there will be a delay of 3 seconds, then copy all files in /udisk-sda1/install/ to /mnt/nand1-1/.

If the automatic upgrade fails, there may be two reasons:
1. Before the copy, the system has not recognized the u disk (the different u disk mount time is not the same);
2. For the u disk without partition, the file system is mapped in /udisk-sda/ instead of /udisk-sda1, so it cannot be copied correctly.

If you can't upgrade with using diffrent u disks, then you connect to the serial port, baud rate 115200, ttl level, to analyze and solve the upgrade failure reason through HyperTerminal.

This problem may be caused by the u disk problem or the oxidation of the gold finger surface of the usb socket (poor contact). You can try another u disk, and check if the gold finger is oxidized.

Thank you, the problem was solved by replacing the flash drive and installing it into the controller without an extension cord.

I have the same problem. How can I solve? I tried to use the different USB ,but does not solved. Can I copy the file directly into the nand1-1 folder instead of the file?
