Hello,
I can compile using 4.7.0 as long as my code fits in rom (without far rom).
However, once my code grows to need far rom, 4.7.0 seems to overflow rom
instead.
I know that far rom has been used successfully by others for over a year
now, so I must be doing something wrong and would appreciate your comments.
Output:

Specialities:
* I'm using a custom MSP430F2617 platform.
* Using Deluge, I set section-start=.text=0x3B00 om tosboot.extra. Thinking
this might be the problem, I have tried reverting that to the standard
0x3100, but this did not help.
The two questions I have are:
1) Why does 4.7.0 seem to overflow rom instead of using far rom?
2) Is it an error that I see a reference
to /home/cire/mm/w/tp/tinyos-2.x/tools.... in my output?
Setup:
* ubuntu 12.04
* TinyOS install yesterday, as per instructions
http://tinyos.stanford.edu/tinyos-wiki/index.php/Automatic_installation
including msp430-47
* PATH is
/opt/msp430-47/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
