Z28 [RK3328] 1/8

Some Time ago I bought a cheap Z28 TV Box fromGearbest for 27€. I was curious about this chip after I saw a Picture of the Rock64 here on Armbian.  When I first connected the Box it only comes up with 720p Resolution, far away from 4K at all.

 

Some other things happened, Rock64 was send to Devs and Developement seems to become more and more Stable, so it tried to check Ayufans Android Image on this Box. I got me the Android Tools and flashed the Image to the box on a Windows Machine . Adroid came up without Network, (as expected) but seeing this Image Booting made me thnking of trying the a Desktop Image on this Box.

The Android Image can be flashed via Android Tools, but not the Linux Image. To make the Box boot from SDCard it has to be Set to Maskrom Mode. This could be easily done with the Android Tool.

1. Start the Android Tool on Windows

2. Go to Upgrade Firmware

3. Load some Firmware for this Box (the one from Ayufan or some of the originals..)

4. Plug a Male to Male USB Cable to the OTG Port of this Box, while Pressing the Reset Button for ca. 5s

5. Now go to "Erase Flash" , Done the Box is now in MaskRom Mode..

 

Just like always prepare a SD Card with an Image and watch Ubuntu comig up on this Cheapo.

 

I am writing now from this Box and even this is an early Stage of Developement, it looks very promising. (Just found that "Take Screenshots" is not working...)

Haha. Amazing. Great to hear that it also works here :) I wonder if I should also not adapt Android to work too.

Porting Android to this is Box would be fine, since the upcoming the Rockbox would be the same Hardware. I saw Widevine on your Android Image :)

I found the Error, it is my USB to Serial converter, when it is plugged in i have to wait. The Box is working when the converter is plugged of...

I am going to look at the solder points tomorrow.

@r1kaomsk, the 4.4.x BSP kernel tried to store MACs in the GPT vendor partition on the eMMC. ayufan changed that for Rock64 images to the SPI flash since eMMC are removable here...
