load ubootloader succeeded, but still cannot flash data into emmc #20

I use RK3288 chip

under ubuntu 16.04

sudo ./rkdeveloptool db rk3288_ubootloader.bin

it showed "Downloading bootloader succeeded.", but still failed to use wl command "Did not find any rockusb device, please plug device in!", or it will hang and no responding

But I can flash image with Android Tool (RKDevTool 2.39) without problem (with same boot loader)

I found the reason.

I was using a Virtual machine (Virtualbox) to operate the device. When I changed to use a physical computer with a Linux to try again, it works

Hi,

Just in case someone met the same error : it's possible with virtual box, you just have to allow the USB Device all the time going under USB parameter and adding it. Just connect it from the drop down USB menu is not enough.

Bye
