This is correct.  Both flash devices map to the CS2 address space (0x02000000 -> 0x04000000).  J4 determines what device actually gets used (i.e. is enabled)

Hello

 

When I was experimenting with NAND programming I managed to corrupt

the NOR. I think both NAND and NOR use addresses 0x02000000...

and if J4 was not set correctly for the mode you were using, corruption may occur.
