I have this MT29F128G08EBEBB that's listed as a problem chip and there is no chip config for it. It's from a Lexar 16GB with controller SM3257EN Q BB. So I decide to look at the ONFI data and see if I can figure out a config to read the NAND. The problem I see is that using the ONFI info the dump size would only be about 1/3 of what I expect it to be. Or I'm just looking at it wrong Smile
My math comes up with 6,572,941,312 but I expect it to be 3 times that size.

I can read with other reader, not zeros. Interesting too, I can get a 224/224 ECC in FE. But I'm just trying to figure out the correct chip read settings right now.
