Is there any way to dump more than 0x100 bytes from nand flash?

Is there any way to dump more than 0x100 bytes from nand flash?

[Calvin Johnson]

Hi,

In U-Boot there is "nand dump <address>" command which is very useful
to check the contents of the NAND page and OOB area.

I tried searching for an alternative in Barebox, and found that we can
use some thing like "md -b -s /dev/nand0.barebox.bb". But this will
dump only 0x100 bytes. In order to increase the size, I need to
compile again.

Is there any way to dump more bytes from the NAND flash and from
different blocks/pages?

How are the experts working with this?

Thanks for your help,
Calvin

please try "md -b -s /dev/nand0.barebox.bb <dump offset>+<dump size>",
e.g.
  md -b -s /dev/nand0.barebox.bb 0+0x200

Sorry, I'm not an expert :)))
