Not a lot of success with this - emmc on a MatrixTV box appears to have three partitions:
boot0
boot1
p1
parted cannot determine the type of the two boot partitions and I have not been able to mount them.

The p1 partition looks like a system/root partition, with bin, dev, lib etc directories. Writing the uEnv.txt file to the p1 partition has no effect - the system shows no signs of attempting to boot.
The bootable MatrixTV SD card has a single partition which simply has a lost+found directory. However, this partition also has what appears to be 7.7MB of free space in front of it - this must be where the system image resides. Again, this area is not accessible as a filesysystem and it is, therefore, not possible to write the uEnv.txt file there.
I'm not sure what else I can try!
