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。
错误 write: No buffer space available write(s, &frame, sizeof(struct can_frame)) 的输出结果为-1; 1. 2. 原因 由于缓冲队列空间不足; sudo su root@super:/sys/class/net/can1# cat tx_queue_len 10 root@super:/sys/class/net/can1# echo 1000 > tx_queue_len root@super:/sys/class/net...
can通信发送提示 No buffer space available 由于缓冲队列空间不足 设置即可 echo 4096 > /sys/class/net/can0/tx_queue_len

是这样的,使用am335x sdk包里面的DCAN驱动,驱动移植配置完毕,使用canconfig等工具配置,测试发送接收都是正常的,然后用两块板子对接can总线,写can socket通信的应用层代码进行发送接收测试,然后在调试过程中出现no buffer space available 这个错误信息,是缓冲区的问题?怎么解决这个问题?请各位高手指教……...
