Trying to compile for the arm943e-s.

Question one. How do I select this from the gcc command line?

Question two: when I do compile I get the following error message:

/cygdrive/c/DOCUME~1/Mike/LOCALS~1/Temp/ccihgTxF.s: Assembler messages: /cygdrive/c/DOCUME~1/Mike/LOCALS~1/Temp/ccihgTxF.s:676: Error: ARM register expe cted -- `mcr p15,0,addr,c7,c6,1' make: *** [ucs.o] Error 1

command line options used: arm-elf-gcc -I blah blah -D blah bla -g -c filename.c -o filename.o

Thanks, Mike

Go to:

and follow your nose to:

+3 GCC Command Options +3.17 Hardware Models and Configurations +3.17.2 ARM Options

then look at the option -mcpu=name

You have already got the answer to question 1.

As for question 2, unless it's changed in recent ARM variants, I believe that mcr requires a register and not an address.
