does anyone know the pinout of rockchip rk3026?

I've taken apart an tablet and i want to reuse it.

 

I've done this in past but this time i have problem finding full datasheet, and finding the jtag to backup and rewrite firmware.

 

All i was able to find was brief datasheet that didn't had the pinout.

 

 

Martin.

    Chinese are known for a lack of technical information. But if you can match the jtags on the board JTAG Pinouts to the chip this may help. Clem

    Yes i've heard about that but this one is tqfp but the rk2926 leaked datasheet has only bga version.

     

    Do they have it mapped same way by the pin numbers ?

    I have asked to a China producer, then I saw the link too. As far as I know yes, the internal features are different in some parts but the pinout is the same as Chinese can reuse the same board designs with the new hardware with minimal modifications.
