正在执行msp430x指令，但mcu不是msp430x

Question

我在cooja中使用sky微尘。对相同代码的模拟在最初的几次中运行良好，但现在突然出现了以下Contiki错误

     [java]  INFO [AWT-EventQueue-0] (MessageList.java:261) - Executing MSP430X instruction but MCU is not a MSP430X
     [java]  INFO [AWT-EventQueue-0] (MessageList.java:261) -

我正在使用最新版本的contiki和gcc。我试着在ant clean之后重启cooja。你知道我怎么解决这个问题吗？

出乎意料的是，问题与环境无关。我发布了问题here，这对我很有帮助。

如果MAX_PAYLOAD_LEN太小或太长，数组无法容纳，则会出现此问题。我将MAX_PAYLOAD_LEN设置为19。
