Hi All,
suppose the image I want to flash is bigger than the available ram in
the unit.
Is there a way to copy the image f.i. in pieces into the flash?
nand write should have a 'continue on last block' option for that purpose.
Thanks!
Jaap

Something like that would be nice.

That could do the trick also. You would have to do some arithmetic to
calculate the next startaddress in the flash.
So there is not an out-of-the-box solution at the moment?

There isn't.
