I have heard it both ways. If you are trying to read a 256/512 nand some people say use r/w +64 command and others say use r/w +256 or +512 depending on which you have. So which is it?

If you want to read a big block Jasper NAND, you only need 64MB of it. Here are the commands for reading and writing:

For 256/512 consoles, you read/write a RAW NAND with
-r64
-w64
as everything after 64MB is just Internal Memory.
ecc files need to written with a rebuilt ecc, so they need
+r64
+w64
EDIT: Blakey got there first - you don't ever need to specify +r/w 256

I just realised when you typed that Martin, thanks for the correctionyou don't ever need to specify +r/w 256
.I am reading a 256 jasper and I'm getting the read error I've been reading about. I am getting some bad blocks. Is this bad or can I proceed as normal so long as the nand reads match.

If the block appears in each read, it's fine.
All that matters is that you have at least two identical dumps.

You aren't making things any easier by helping him out, if he wants an answer then I am sure he can familiarise himself with the forum's search feature.
What are the implications of a bad block? I am getting 250 and 210 error if that matters.

That shouldn't be an issue, error 250 usually means a physical bad block which is fine.
Just read a couple more times and keep doing so until you have at least two matching dumps (0 non-matching blocks found).

I only ask because people are saying to remap it to make it all be good. Doesn't the bad block mean that if I wanted to save a file to the internal 256mb memory, it may be problematic? I am just trying to avoid future problems but like I said I don't know what the implications are.

Ah I see now. So is that recommended and if so is there a tutorial for this? I found a video one but it's hard to see in the video what they are doing. I prefer to use jtag tool.

JTAG Tool will re-map bad blocks, I don't know where the feature is in the new version.

Yeah use JTAG Tool. I believe it is the best if you're new to JTAG or if you want one program that does everything.
