Designing compatible hardware for the .net micro framework

[Bekhit@discussions.microsoft.com Amr Bekhit]

Hello,

I have recently come across the .net micro framework and I am starting to
evaluate it to determine if I should use it for an upcoming project. As with
other users, there didn't seem to be much information regarding the design of
custom hardware. Although I do plan on getting one of the evaluation boards
for prototyping, ultimately, I will be designing the hardware myself,
deciding on the BOM and layout the PCB. I have a few questions:

- The website presents a list of various ARM cores which the framework can
run on. Assuming that I choose a device with a compatible core and meet the
minimum memry requirements, can I choose any ARM device I want? Does it
matter if the ROM/RAM are external/internal?

- I currently have an LPC3250-Stick, an evaluation board for the LPC3250 ARM
9 device. The board has 32MB of SDRAM and 128MB of FLASH. According the
Getting Started section of the micro framework website, I need a minimum of
64KB RAM and 256KB Flash, so I should have more than anough memory on this
evaluation board. Could I run the .net micro framework on the LPC3250-Stick?

- Is there a detailed specification on the hardware configuration needed in
order to deploy a .net micro framework project?

Thanks,

--Amr

Hello,

the LPC3250 you are describing is certainly suitable for the .NET MF. You
can actually use any ARM core, provided that the memory requirements are
satified.
In order to deploy applications you will have to implement at least one of
the following transports: USART, USB or socket. TYpically USB and socket are
the fastest choices, but USART is the simplest.

We have no other requirements

Thanks
