eMMC not recognized

[cfdiaz]

1) connect the adaptor with eMMC to Ubuntu (I assume desktop). Does it show up in Disks utility or when you do?: 

Code:

sudo fdisk -l

2) If the above doesn't work, please follow the instructions here and see what you get when you do 

Code:

rkflashtool n

1) It doesn't show up with eMMC placed. If I connect the adaptor without eMMC then show up as "SD card reader".

2) I need to adquire a USB A-A cable, I'll try when I have it.

Also try a Android microSD to eMMC image from here, but screen remains black after "Rock 64" initial message.

Thank you for your help
