Dear Kok:

The macros `NAND_CTL_SETCLE' and others need to be defined for the hardware in your system to set/clr the CLE (CommandLatchEnable), set/clr ALE (Address Latch Enable) and a few others.

How these work is described in the readme for nand and once defined, this code will compile and work properly.

The issue is that each board has a different implementation and macros are required to accommodate the various addressing schemes used by hardware designers for nand access.

Hi; I have the following error when building nand_base.c:

Any insight is appreciated.
