The only open source assembler I know of is the GNU "as" assembler
(also called "gas"). This uses the standard GNU syntax, which is a
cross-platform standard used for many target processors, but
unfortunately, it does not use the ARM standard syntax you typically
find with commercial ARM assemblers.
 
If anyone knows of a different open source assembler, please tell me
about it!

Their are a number of good commercial assemblers, but I'd probably
recommend the one that comes with IAR Embedded Workbench. Their free
version has a 32K limited C compiler, but their assembler does not
have a code size limit as I understand it, and their CSPY debugger
works with assembler code, also.

For a tutorial on how to code in assembler for the ARM you can
download the "ARM ARM" (the ARM Architecture Reference manual). I
think you can get this from arm.com, or order a hardcopy from amazon.com.

lpc21isp is a fine open source program that can do this. Join this
yahoo group and go to their files section:
