eMMC not recognized - cfdiaz - 01-16-2018

Hello,

I Bought 64GB eMMC and USB ADAPTER FOR EMMC MODULE from pine64 and nothing happens when I connect it to computer, if I connect only the reader without eMMC then a light is turned on and computer detects the device.

Tested on diferents computers.

Can the memory be broken or maybe I'm doing something wrong?

Thank you.

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 Smile

What about ?

Code:
sudo fdisk -l

Also, it can take a long time for Android to boot the first time from a SD card.

Wait several minutes for Android, maybe not enough. SD card become unusable after some attempts.

Thank you.

Hmmm, perhaps you could join the IRC and have someone help you troubleshoot further and determine if its a fault with the eMMC itself.
