i know how to de solder the 2gb nand flash but is it possible to upgrade it to let say 4gb or 8gb nand? Is it any limitation?

You can buy them with 2, 4, 8 or 16GB installed so I shouldn't see why not. I've got the 16GB

i buy it with 2gb..before this i have removed the nand flash as i thought its bricked because of the nand flash is broken..then i resolder it and flash with new fw i get from Xaueious and it worked..its hard to get the nand flash replacement here..unless i can get from the pendrive..

hi could you please explain how to do ???? bernie67

since the new flash is empty, it is impossible to flash it following the usual flashing procedure and we have to use "needle"-method when flashing first time after soldering new flash to the board, am i wrong? and of course flash should be of those supported by RK2808 SoC, yes?

 

[hucqim80]

yes..you have to do the "needle method"..I want to try this but i don't have any nand flash at the moment..
