Hello sir,

I'm working on Hyundai GMS30C7201 board, using ARM Linux V.2.4.18 Rmk 3.

In addition to NOR Flash, we mounted KM29U64000T 64Kbit NAND flash on the
board to use as a disk, I changed sample VIA board driver according to the
directions given in the Document directory and by referencing addresses in
hardware.h (NAND_BASE 0xf2000000, physical address is 0x08000000).

When I boot the system, VM error is appearing, as below and system is
crashing. When I test ioremap for physical address 0x0800000, system is
giving no nand flash found message.

Please inform me about the casualities, if you have experienced with such
problem.

Thanks,
