使用CAN接口过程中出现“No buffer space available”提示信息,相关打印信息如图A-1所示。 图A-1打印信息 原因分析 执行命令./cangen can2 &发送数据时,buffer空间不够。 解决方法 执行如下命令,查询CAN口详细信息。 ip -details link show can2 执行如下命令,修改缓冲队列空间长度。

write: No buffer space available write: No buffer space available 因为不可预知另外的can有没有连线,或者有没有挂载上等待接受,如果单方不断发送数据,是不是就会把缓冲区占满,那么有什么比较好的解决办法可以克服这样的情况。 经过这么多天的代码追踪,终于解决了这个问题。
