<tt>You are requesting about 2000 512x512 blocks of memory. Try
either smaller nxb/nyb or use maxblocks setup option to lower the
number of blocks. I believe some information about FLASH memory
allocation is provided in the user's manual.<br>

<p>Hmm, somehow Flash is statically allocating more than the
Linux 2GB limit. I'm surprised that anything is statically
allocated.

<p>I tried to increase the number of cells in my 2d model to
512 by 512. It will not compile at this size and I get an
error about static memory. Is there a way I can solve this?</p>
