Please have a  test  for changing  R1 from 3K9 to 470ohm.
and Please upgrade to the newest software.

I had a test with TC58NVG2S3ETA00
and use 64MB file.  Writting and verifying.   and verifying again  . there was  no problem happend. Your problem must be the problem of signal disturb
Please do another test: change the capacitance C01 from 0.1u to 10uf.

this is my test result:

I am sure this is a hardware problem .

the value of  the file : 0xBF377B00
and read from chip:     0x20377B00

in fact: 20 is the next byte.  
Nand chip received an additional interfering clock signal when reading. so got a next byte value.

If all NAND chips are wrong when testing, try it with another NAND Adapter.or you DIYT a adapter by yourself.

Please wait, I will do more tests to see if I can modify the software at the same time to improve its adaptability to reading,

This problem is not achievable with every chip. After a day of testing, several possible causes were modified. I think it should be fine.


1. please download lasted software . and installation

2. replace R01(3K9)   with 470ohm
3. replace C01(0.1u)  with 2.2u
4. Connect a wire as shown in Pictures.
