Hi Artem,

	do you remember about my flash problem?

>>/>mount -t jffs2 /dev/mtdblock5 /mnt
>>/>Newly-erased block contained word 0x4c004c at offest 0x00040000
>>Newly-erased block contained word 0x4c004c at offest 0x00030000

I have found the cause : the Samsung S3C4510b when access to the memory =
use
the "cache" by default.
If you have to disable it (like while you program the flash) you have to =
'or
0x4000000 to the base address.

So I have modifyed the file "cfi_cmdset_0002.c" as follow :

	for esample: "do_erase_chip" function

		...
		chip->start |=3D 0x4000000; //my modify!!!!!!!!!!!!!

		chip->state =3D FL_ERASING;

		ENABLE_VPP(map);
=09
cfi_send_gen_cmd(0xAA,cfi->addr_unlock1,chip->start,map,cfi,......


I did the same for every "cfi_send_gen_cmd" : the 3rd parameter has been
ored to 0x4000000.

What do you think about this modify? Do you know a better way?

Now I still have one warning msg :=20
	"Warning: DQ5 raised while program operation was in progress,
however operation completed OK"
Can I ignore this msg?

Thanks!

	Massimo.
