Unable to clone nand-flash

[Pragmatiko]

Hello guys,
I am going crazy for to clone nand flash MT29F8G08ABABA WP of Philips TV.
With programmer i read original flash but if i copy dump on new flash the tv wont turn on.
With original flash tv work.

Can someone explain me why?

Thank you.

Thank you.

When you read the original you saved it as a dump file. Can you compare a read of the cloned nand flash to the dump to verify.

Well, when i do a verify i see that some bytes also if same value are allocated in different address.

If that's the case then it hasn't made a true copy and the clone would be invalid.

Which would be the solution for to get perfect clone?

Re: Unable to clone nand-flash

Unfortunately I'm unfamiliar with the IC. All I can suggest is try and google as much information as possible and double check you programmer settings.

which NAND programmer you have?

SmartPro 5000U Plus

Maybe this programmer cannot clone or repair bad memory blocks from MT29F8G08ABABA, he just ignore them.

Re: Unable to clone nand-flash

have you program any other NAND chip with this programmer?

the reason I ask, sometime the software for the programmer isn't correct for NAND memory chip.
I had a Wellon VP896 and Its never read or write to the NAND memory chip I was trying to read/write too. Tech support at wellon claim their programmer can read/write to NAND chip. I never got a successful read.

when reading a NAND memory the software shouldn't read bad blocks, if there is an option in the configuration setting about reading bad blocks you shouldn't read bad blocks.

when writing bad block should be skip, the programmer software should control this function

Re: Unable to clone nand-flash

I will try to contact programmer.support for to ask the correct programmmer configuration for to have a perfect clone.

Yes i have already cloned some.others nand and ever worked.

Re: Unable to clone nand-flash

Solved, need to put right programmer configuration

Re: Unable to clone nand-flash

also I notice that some NAND memory chip has no bad blocks or very little. does your software tell you how many bad blocks the chip have if you erase the chip.

Most Micron NAND memory I have read has no or very little bad blocks.

I have the TNM5000 and its works great!! no problem reading or writing to any NAND memory chip !!!

the software is well layout with good features.

Re: Unable to clone nand-flash

yes you don't want to read bad block with copying NAND memory. doesn't the software inform your how many bad block is there when you erase or do a blank check?

I am facing the same problem with this device on ChipProg 481.
Can you please help?

Re: Unable to clone nand-flash

You need to ask right config device to support of you programmer.

Re: Unable to clone nand-flash

Hey Prag can you share the config you used? I am trying to clone MT29F2G16ABAEAWP and the chip will never verify. it has the wrong data in the wrong address
