At-Home Amature Development

ohad o.

Hi guys,

i'm an amature programmer and my main interests  lie in the field of OS programming.
lately i've been thinking about how much i'd love to go a layer below the OS - developing something from scratch!
as i'm familiar with ARM (well, more with the instruction set and the results of compiling C/CPP code) i'd like to purchase
a very simple straight forward (i'd appreciate any tip but i'm on a budget) ARM development board
for the my at-home programming games.

i'm looking for something that i can communicate with via my PC without too much welding,
where i can write my own code that will be loaded at boot time (i'd very much like to BE the first code
that's running and not a commercial bootloader - but i'm not picky about this).

it also needs to be easily debuggable, as i obviously will have no software framework.
also, i'd like to have I/O-s i can use because one of my first goals is to write my own "raw" interrupt handlers.

since i'm just starting, a very simple board (even without mmu support - though i'd like to tackle that as
well on day) with little flash and little RAM will do just fine - i don't intend to compile linux or something
along that line - it will be strictly my code.

a search in google revealed way too many possibilities and it's not clear which boards allow
comfortable amature development.

i was hoping you guys could get me pointed in the right direction and maybe some other people will
benefit from you're replies.


thank you all in advance :)

    It depends on what you want do really.

    mbed (mbed.org) gives you a cheap/easy way into bare metal programming with a M class MCU. 

    If you want at some point to run Linux (or a n other OS) then a Raspberry Pi is an option (http://www.raspberrypi.org/), or if you want something with more processing power (and unfortunately a higher price tag) then a Panda board (http://pandaboard.org/).  To do bare metal programming you'd have to buy additional tools for these boards, such as a JTAG interface unit.

    hi ttfn,

    first of all - THANK YOU!
    mbed looks exactly like what i've been looking for! it looks to be a user friendly package that
    lets you code your heart out and allow me to execute at the earliest stage!

    i will research it a bit more and let you know if i buy it.

    again thanks - i can't belive how quickly you've answered :)
