The question on this was posted by inquisitor in the FPGA section, but here is the answer again for those who look here for it:
When you purchase a Numuru board, a link to the download site will be sent in each e-mailed order confirmation. You will then have 28 days to download the complete Namuru source code 3 times. This includes all of the reference designs. This is available as a ZIP file of about 20MB containing the very latest code.
We use this mechanism to avoid unwanted attacks on the site and corruption of the source code.
If you have already purchased a board, and you missed the 28 day window or just need an update, follow this link, http://www.dynamics.co.nz/index.php?mai ... ducts_id=8
to place an order for a free download of the source code only.
You will receive an e-mail with an order confirmation and a download link as described above.
From time to time you'll see posts on this forum (in the General section) about various updates from the developers.
