Greetings,
I'm not 100% sure but I think I found the problem. The nand drivers used
doesn't recognise the 2k pagesize. I've got a linux where the chip is
not supported an I change the necessary values to the apropriate ones in
nand_ids.c. The chip is recognised but the programs probably interprete
this as a 512k pagesize.
A small test Programm brought some more clarity in the whole situation.
At first we wrote some bytes with a ICD in the NAND.
A Linux Test application - I used a standard read command (see below)-
could read out the appropriate code but nanddump could not.
Testprogramm reading the first page:
Code (READ1_1 = 0x0 ; READ1_2 = 0x30):
...
// Read first Page
printf("Trying to read the first Page\n\n");
nand_mem_write(CLE,READ1_1);
nand_mem_write(ALE,0); //Collumn address bit 0-7
nand_mem_write(ALE,0); //Collumn address bit 8-11
nand_mem_write(ALE,0); //Row address bit 0-7
nand_mem_write(ALE,0); //Row address bit 8-15
nand_mem_write(ALE,0); //Row address bit 16
nand_mem_write(CLE,READ1_2);
for (i=0 ; i<264; i++) {
Address=i*8;
printf(" Addr %x: %x %x %x %x %x %x %x %x
\n",Address,nand_mem_read(),n
and_mem_read(),nand_mem_read(),nand_mem_read(),nand_mem_read(),nand_mem_read(),n
and_mem_read(),nand_mem_read());
Output:

debugger test programm.
