Your best bet would probably be to use 4M of flash and 8M of
RAM. When building software for the ETRAX 100LX, the OS and
applications are compressed and then stored in flash. Upon
boot, the code is uncompressed and is then executed from
If your application needs much RAM, you might want to
consider using more than 8M of RAM, but this is hard to say
without more information.

Again, this depends. The developer board boots up somewhat
faster than four seconds.
