Problem with writing SAMSUNG NOR

[gataka]

Hello,

I have very strange problem wile tempting to flash Samsung NOR chip.
I am using Progskeet and WinSkeet40000 flashing program.

I read the NOR with no problem. But when I try to write it it gave error when Verifing sectors from 2048 to 3438 :

[2011-10-01T13:00:36] Verifying sector 2048
[2011-10-01T13:00:36] Verification of sector 2048 failed
//-//-//-//-//-//-/all sectors in bitwin/-//-//-//-//-//-//-//
[2011-10-01T13:00:46] Verifying sector 3438
[2011-10-01T13:00:46] Verification of sector 3438 failed

It give me the same error even if I try to erase some of this sectors. So I assume the are in read only status.

When I write the original NOR there is no error and the console work. But I assume the program cant write it again and the sector are not tauched and they are with the original information, thats why there is no error.

I try many times. What ever I try the same sectors are with error.

I check the chip and tes it with multimeter every thing seems to be correct. But if there is nothing els to try will resolder and solder it again.


I have flash SAMSUNG NOR befor, some times I get error but in different sectors and with some attempts all is ok. But this one is different I just cant write on this same sectors what ever I try.

The console is CECH-2004A with data code 9B. I receive it with version 3.66.

Any ideas?

Use Winskeet4000-2

Where I can download it?

I re-solder the chip and I get the same thing. Its like this sectors are read only.

Edit :

I found the newer version of Winskeet4000. I will try today with it.
