c - 执行 msp430x 指令但 mcu 不是 msp430x

Question

我在 cooja 中使用 sky 微粒。相同代码的模拟最初几次运行良好，但现在突然出现以下 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) -

Java 堆栈跟踪:

我正在使用最新版本的 contiki 和 gcc。我尝试在 ant clean 后重新启动 cooja。关于如何解决问题的任何想法？

Answer 1

出乎意料的是，问题不在于环境。我发布了问题 here这对我有帮助。

如果 MAX_PAYLOAD_LEN 太小或太长而不适合数组，则会出现此问题。我已将 MAX_PAYLOAD_LEN 设置为 19。
