    Hi,

    The PC runs Windows or Linux?

    Did you try with the prebuilt U-Boot binaries in the Processor SDK to see if the same issue happens?

    Hi, Bin

        Thanks your reply.

        My host pc is windows, and i just try it use prebuild image, the same thing happened, it`s so bad.

       I try to enable debug and want print some log, the new spl binaries size is 119k and looks like it can`t run normally. 

       To build debug binary, the change is:

    I am not sure if the change is correct, any comments welcome.

    By the way, whether or not spl binary tansfer, the uniflash Progress % always is 0.

    hope your reply.

    thanks.

    Hi,

    Is this on Windows 10 or Windows 7?

    I only use Linux PC and don't have a Windows computer to run this test, but I saw many reports on internet that Windows 10 requires signed USB RNDIS driver for USB devices to be enumerated as USB RNDIS device, so many people got stuck with Windows 10.

    My host pc is windows10, you are correct, It looks like the RNDIS driver is installed, but it's not optimal.

    I reinstall the rndis driver provide by microsoft, everything is ok.

    Thank you very much.
