Hi... using Jtagtool ive dumped 3 nands which are all the same but have read error 250 at Block 2 and also wont open up in 360 flashtool??? And now i cant seem to create the ecc file and wondering if this is why?? i get the Assertionerror. Using nandx and coolrunner on xp. Tanks for any help in advance

traceback (most recent call last):
file "build.py",line 340,in <module>
unpack_base_image(image)
file"build.py", line 98 in unpack_base_image
assert CB_A and CD
AssertionError

UPDATED..
So i decided to do another console and getting same issue of dumping nands that cant be opened or worked with so had decided to reinstall windows etc only to find same issue so now wondering if its my Nandx??? I gonna reflash it again to see if that makes a difference but after that im at a complete loss.

UPDATED
And so i reflashed my nandx as another option and yet same issues. Now ive prob done from 25 -35 jtags and never had a nand reading issue yet and this is really driving me nuts.

I did write this topic on another forum and the only response i had was it could be the nand with bad blocks but tried a falcon and got 3 full dumps identical but yet again all incorrect or corrupt images???

Any help here is well appreciated and thanks in advance.

Yes - block 2 is needed.

do this:

example: your nand dump is called nand.bin

nandpro nand.bin: -r16 bb1.bin 3ff 1

nandpro nand.bin: -w16 bb1.bin 2

Try opening it up in 360 Flash Dump tool now.

I suggest you start to learn how to use nandpro at commandline then, seeing as you're obviously not doing consoles for yourself!! Depending on a GUI is always bad and will get you so far, however you'll come unstuck as you have now.

As for not being able to open others in 360 Flash Dump Tool, manually dump the nand:

nandpro usb: -r16 nanddump.bin
