Hi all,

I am using K2H evm with ramfs boot.  I want to check the cpsw logs, it is prefered to check these logs from ARM side, so how to check these cpsw_stats and PA stats to know that the packets are reaching upto that points through ethernet.

Regards

Tushar

    Tushar,

    You can try the below sequence for check the cpsw stat,
    root@keystone-evm:~# ls -l /sys/devices/soc.0/2090000.netcp/cpsw/stats
    root@keystone-evm:~# ethtool -S eth0

    root@keystone-evm:~# echo 0 > /sys/devices/soc.0/2090000.netcp/cpsw/stats/A
    root@keystone-evm:~# echo 0 > /sys/devices/soc.0/2090000.netcp/cpsw/stats/B
    root@keystone-evm:~# ethtool -S eth0


    Please have a look at this wiki, get more detailed information.
