RockChips NAND driver & remote upgrade

Postby nmontmarquette » Mon Jun 06, 2016 2:35 pm

We are looking for technical help with the RockChips NAND driver.
We have several in-field customers that would greatly benefit from the RockChips NAND driver update.

Because we need the RockChips NAND update fix, we have to proceed with a low-level format of the entire storage media, leaving the device helpless for several minutes.
We understand we would need a specially made boot & kernel ramdisk working without any storage media and also access to low-level NAND driver functions.
We understand we would also need to update bootloader from 1.22 to 2.25 ( which is a pretty big deal on its own ).
This is all to be done "live" without usage of USB connection.
We understand this is a quite challenging update.

We are first looking into whether a very specific technical reason would make this completely impossible (e.g.: the relevant code being in mask ROM for example )

Any help answering this query is very appreciated.
