[oc] EEPROM Programmers using FPGAs? now its EPROM vs FLASH time



Dani,

I don't know much about FLASH memory, more acquainted with EPROMS from
previous projects plus EPROMS are easy to get here. The development
system is using 4 EPROMS to give me 4MBytes of space to store a copy of
ucLinux on it (should be enough? lol). Final one will use a smaller
EPROM or FLASH perhaps so I can send updates in the post or via the
Internet.

My final ucLinux computer is aimed to cost less than £25 (thats about
USD $38), hence why I'm worried over the costs. There are 8bit 'Rabbit'
computers on the Internet for $25 but mine is 32bit (OpenRISC hopefully
so watch out Damjan!)

How easy is it to use FLASH? As easy as SRAM? What sort of access speeds
do you get from them? And how much do typical units cost?

Paul
