ROC-RK3308B-CC V1.0串口打印问题

肖观明

怎么样才能关掉以下的串口打印信息：

[   53.382472] ==> rtl8188e_iol_efuse_patch
[   53.720862] RTW: wlan0- hw port(0) mac_addr =ac:5d:5c:fb:29:fa
[   53.721598] RTW: p2p0- hw port(1) mac_addr =ae:5d:5c:fb:29:fa
[   53.727927] RTW: nolinked power save leave

rtl8188eu打印信息：
方式一: 连上wifi成功后，就不会出现以上wifi相关的打印信息
方式二：echo 0 > /sys/module/8188eu/parameters/rtw_drv_log_level
方式三：修改驱动源码把rtw_drv_log_level的默认值改0
