This is just a small post to say that info can be found in all sorts of places. This pic has some info on the purpose of some of the discreet components, and I thought it may prove useful, or food for thought to someone.

I found this looking for info on Spectek nand chip PFF69, ID: b5 a4 64 32. at https://www.aliexpress.com/item/32984434603.html

if you ever wondered what the resistors were for, this may help.

Code:
JUMPER SETTING.
Moving  R6 to R7 for 2-chip mounted.
Only one NAND Flash, mounting to U2's side.
R43 for Common NAND  (R43 Close ,R44 Open);Default Set.
R44 for 3D NAND   (R44 Close ,R43 Open)
