[mc1322x] building on a mac

[Dean Hall]

Update to my instructions:

- sudo port install arm-elf-gcc
+ sudo port install arm-elf-gcc +interwork

With this change, I still get interworking warnings and a curious  
error in the same line of start.S that was mentioned in today's "ROM  
vars" email thread:

/opt/local/lib/gcc/arm-elf/4.3.2/../../../../arm-elf/bin/ld: Warning: / 
opt/local/lib/gcc/arm-elf/4.3.2/../../../../arm-elf/lib/libc.a(lib_a- 
strlen.o) does not support interworking, whereas per_redbee- 
econotag.elf does
../src/start-romvars.o:../src/start.S:124: undefined reference to `no  
symbol'
collect2: ld returned 1 exit status

Many of the binaries are built.  For example, blink-allio_redbee- 
econotag.bin is 2520 bytes (I post this for comparison, I don't know  
what its proper size should be; please let me know if this is in the  
ballpark).

I've installed the FT2232 drivers and get these devices when the  
econotag is plugged in: /dev/tty.usbserial-000030FDA and /dev/ 
tty.usbserial-000030FDB so I'm presuming the one ending in 'A' is for  
the JTAG and 'B' is for UART1 (I saw this in the docs somewhere).

Then I installed 2 CPAN modules:
     http://search.cpan.org/~cook/Device-SerialPort-1.04/SerialPort.pm
     http://search.cpan.org/dist/TermReadKey/ReadKey.pm
to get mc1322x-load.pl to run:

$ ../tools/mc1322x-load.pl -f blink-green_redbee-econotag.bin -t /dev/ 
tty.usbserial-000030FDB
..............................

The periods lead me to believe the perl script is not receiving data  
from the UART.  The FT2232 shows up on my USB scan.  I'm just not  
transferring data yet.

another step closer,
