Error reading and writing in several nands family TC58NVG1S3HTAA, TC58NVG0S3ETA10, H27U4G8F2DTR, TC58NVG1S3ETA00. I can't copy using tl866plus. Ja with other programmers will ok.

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

I made the correction of the resistor from 3k9 to 470. This is with the latest update. however when I read the data it is different when I ask to check. When I make a copy it doesn't work, the TV is dead.

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:

The nand data here is 285mb. when I look at the buffer the data is just right in the header the rest is corrupted or different. not being able to send the 2 files because they are large. even compressed the two of about 130mb

I placed a 10uf capacitor for overcurrent protection. I left with a 5uf capacitor but the same problem continues. it seems to be an algorithm problem and not a hardwere one.
作者: admin    时间: 2020-4-21 08:14

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.

what should I do? any other chip other than nand reading beauty. But when and nand corrupts the file while reading.
作者: admin    时间: 2020-4-21 17:27

If all NAND chips are wrong when testing, try it with another NAND Adapter.or you DIYT a adapter by yourself.
作者: marck3    时间: 2020-4-21 17:45

I don't think it's the adapter, not least because the tl866 checks the pins. It may be some internal interference in the programmer. as i said flash memories read and write ok. but the memories are not having a problem during the reading itself.
作者: marck3    时间: 2020-4-21 17:48

I would not be able to send me the programmer's electrical schematic to see if it is possible to add capacitors in the power grids to see if this interference effect that you say so much attenuates.
作者: marck3    时间: 2020-4-23 16:25

I left two mega links above in the post a good file and one read with the tl866plus. download them and try to see where the problem is.

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,
作者: admin    时间: 2020-4-24 13:57

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.

NOW AFTER THE NEW UPDATE AND MODIFICATION YOU HAVE READ BEAUTY. I'M GOING TO TEST THE TV AND POST THE RESULT.

I TESTED A TV TEST WAS 100%. READ OK AND RECORD OK. THANK YOU IF ANY QUESTIONS APPEAR HERE.

Hi, what is the value of C02 ?

    As a User:  For those that want to have the latest board, remember, that a new version (V2) exist,  with this modification already done on PCB, and not expensive....just talk :-)  Unfortunatly  Xgecu doesn't talk
about it's existence...
