如何消除我在make TARGET=sky 上遇到的错误？
错误 1：（.text 不适合区域 rom）

我使用的是 mspgcc 4.6.3 版。一些网站建议使用 mspgcc 4.7 版来摆脱ERROR 1。
按照https://github.com/contiki-os/contiki/wiki/MSP430X 上的说明操作时，出现以下错误：
错误 2：（不支持配置 msp430-unknown-none）
checking whether times is declared... yes
checking whether sigaltstack is declared... yes
checking whether madvise is declared... yes
checking for struct tms... yes
checking for clock_t... yes
checking if mkdir takes one argument... no
*** Configuration msp430-unknown-none not supported
make[1]: *** [configure-gcc] Error 1
make[1]: Leaving directory `/home/taare/tmp/gcc-4.7.0-msp430'
是否正在尝试更新 mspgcc 以摆脱 ERROR 1 的正确方法？
如果是，我该如何解决ERROR 2？
如果没有，我该如何解决ERROR 1？
【问题讨论】：
-
您可以在这里获得 msp430 4.6：simonduq.github.io/resources/mspgcc-4.7.2-compiled.tar.bz2
-
这对您的问题没有帮助，您的闪存空间不足 6342 字节。您无法为 Sky 构建任何东西。选择另一个 msp430 平台。
-
谢谢！其他的 msp430 平台是什么？还是需要程序在本地运行以满足内存限制？
-
contiki-os.org/hardware.html - 你至少需要
msp430x之一。 -
@kfx 这个问题应该不回答吗？
