I got the prices for the NAND flash. It looks like "you can't boot from it" but you can "use it as your root file system"... which is what we would be using it for. ---------------------- Dear Mr. Carlson, The 128MB NAND FLASH is $15 each, the 256MB NAND FLASH is $20 each, and 512MB FLASH is $30 each. The EP9302 is not capable of booting from NAND FLASH. It can used as Linux root file system. The optional A/D converter is currently unavailable due shortage of parts. _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
