Configuration msp430-unknown-none not supported

问题

How do I get rid of the error I got on make TARGET=sky?

ERROR 1: (.text will not fit in region rom)

I am using mspgcc version 4.6.3. Some sites suggested to use mspgcc version 4.7 to get rid of ERROR 1.

While following the instructions on https://github.com/contiki-os/contiki/wiki/MSP430X I got the following error:

ERROR 2: (Configuration msp430-unknown-none not supported)

checking whether times is declared... yes

*** Configuration msp430-unknown-none not supported
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory `/home/taare/tmp/gcc-4.7.0-msp430'

Was trying to update mspgcc a correct way of getting rid of ERROR 1?

If yes, how do I solve ERROR 2?

If no, how do I solve ERROR 1?

回答1:

Answering my own question for future users.

Even after optimizing the code if section '.text' will not fit in region rom error persists then it can be solved in following ways:

Use any of the other contiki platforms according to the radio needed.
Try updating your mspgcc to latest version. [This might not always solve your problem. On some other forums I read this suggestion,so I have listed it here.]
