出现[ 324.952121] omap_i2c 44e0b000.i2c: controller timed out

在做一个管理通道,在初次建立TCP连接,设备回进行认真。

程序暂时跑在beaglebone black的板子上,每次在处理认证过程的最后一个包时候就出现内核打印。


[ 324.952121] omap_i2c 44e0b000.i2c: controller timed out
[ 325.971994] omap_i2c 44e0b000.i2c: controller timed out
[ 326.991932] omap_i2c 44e0b000.i2c: controller timed out
[ 326.997452] dummy 0-0034: Error -110 reading from cec:0xfe

请问这个是什么原因?看打印应该是i2c的问题,但是我现在暂时还没用到i2c。

最后一个error就不知道是啥了。请帮助下我,谢谢各位了。
