Hello everyone!
I have a problem with my warp7 board.
I've already read every topic or post I could find on the Internet.
I did everything like in this tutorial: Warp7 Yocto : Part2 : Flashing Warp7 binaries or user guide from github.
Unfortunately I could not flash new kernel to my warp7. I am using Ubuntu on VirutalBox as a host computer.
The problem shows up when I try to mount eMMC space, using uboot ums command for that. (=> ums 0 mmc 0)
It works but only partly. My host computer detects some memory mounted after "ums" command. But something is not right. And when I am trying to flash kernel some problems show up.
Warp7's eMMC memory shows up as a sdb device.
At first when I tried to flash kernel it showd that "no mdeium found".
Then "no such device or address" even tho when I checked by diffrent commands you can see that there are 3 partitions.
I even checked that on Windows and on OS X. Both systems showed one partition "boot imx7s-"
I don't know what I am missing and where the problem is 
I wanted to flash new kernel to have enable wifi.
Here are some photos:
If anyone can help me solving this problem I will be so, so grateful!
