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

    thanks but the board doesn't have anything that would look like jtag.

    The test pads on other side of board are spread out evenly, and i can't get trough.

     

    Why can't anyone do it like all winers tek. they genuinly put jtag on sd card making it incredibly easy to reprogram their MPUs. you don't even need to take off the cover. just stick an sdcard like adapter connected to jtag.
