Hi Sergei,
Now I've cleaned it up and get 2C DC 90 95 each time...tested 4 times.
Still 00's on K9K2G16.cfg
Read_ID 2c dc 90 95 Error
H:\Nand\Nand\K9K4G08.cfg
MNG = Samsung
ID = ec dc c1 15
Bits = 8
Page = 2112
Block = 0x21000
MB = 512
COL = 2
RAW = 3
READ = 30
SBACK = 0
RE_Down = 2
RE_Up = 1
SE_ = 0
I get 528Mb (540 672kb) dumps, but if that is the original size I don't know as the packageing don't tell.
I also see FAT, check 300k dump in container.
Regards Bosse

Its ok.

Because K9K4G08 is 512MB.
And MB field in config set to 512.
What original size?
What give read_id in second bank?

Hi Sergei, I don't know what the original size is...as there is no marking at all on the chassie.
Reading from bank 2 give's us this:
Read_ID 2c dc 90 95 Error
H:\Nand\Nand\K9K4G08.cfg
MNG = Samsung
ID = ec dc c1 15
Bits = 8
Page = 2112
Block = 0x21000
MB = 512
COL = 2
RAW = 3
READ = 30
SBACK = 0
RE_Down = 2
RE_Up = 1
SE_ = 0
And just 00's on bank 3 and 4, so I presume that this is a 1Gb nand?

I've now checked the second bank reading, and there is just FF's.
And I read it twice, so I think that bank is just empty...right?

I look partition size in boot sector
There is 1GB.
So you need make 2 dumps with K9K4G08.
Each 512MB.
Second dump can be empty.
I think its
Block_Number / 0000
Marker 513/512
Calculate Block_Size!

Hi, I'll need some guidence here.
I've been trying to check the block sizes, but I'm little unsure how.
This is how far I've come:
I took the two dumps and joined them by dump, got 1.03Gb file.
I opend it up in Flash Extractor, did a FAT search and found it.
The end of that sector is 00 00 FF FF EE 0F (0xcc7200), the next one down is: 00 00 FF FF DE A6 (0xcc7410), next after that is: 00 00 FF FF CA 81 (0xcc7620)...How to calculate the block size?

Okey, now I get it

Some god data some corrupt data, is there any other adjustment to try?
