I have to design a new hardware with a uP (not determined yet) to run JavaME applications.
I’ve searched information about how do it, but for the moment it has been useless.

Can anyone explain how I can do it?

From what I found in my search:
– Using a uP (ARM for example) with an OS (ie: Linux) (using JIT for better performance)
– Using a uP with Jazelle. Do I have to use also an OS???

The application is an alarm control system, so it doesn’t need graphical interface.
Minimal requirements are: ethernet port, 2 UARTs, SPI bus, I2C bus, min 16MB ram, min 4MB rom, IO ports.

Any suggest?

Regards,
Juanma

    Since you are using JAVA application, I guess ARM926EJ (with Jazelle core) might be helpful.

    What I am not sure is, why would you need a Java application for an alarm controller?

    Anyway,

    • Step-1: Decide on the microcontroller
      (ARM with Jazelle) seems to be a good
      bet, considering the large number of
      tool chains and eval boards already
      available
    • Step-2: Based on your requirement
      decide on an eval board from a
      vendor. Most likely, the vendor will
      also give you, the schematic, ported
      embedded linux version with the
      associated drivers
    • Step-3: On top of the embedded Linux
      write your application
    • Step-4: Check the final RAM and ROM
      size after you finish developing the
      application
    • Step-5: Modify the schematics and
      design your own hardware

    This is normally how we develop embedded hardware …
