Tool/software:

Hi,

We operating AM3352 with Linux version 3.14.26, Dual MAC mode.

1. PHY switch connect to AM3352 RMII1, and disable MAC2  Ping successful,.After loopback network storm test, it can self-recovery

2. PHY switch connect to AM3352 RMII1, and enable MAC2  Ping successful,After loopback network storm test, it can't self-recovery unless ifconfig eth down/up

3. PHY switch connect to AM3352 RMII2, and disable MAC1  Ping  failed. 

4. PHY switch connect to AM3352 RMII2, and enable MAC1  Ping successful, After loopback network storm test, it can't self-recovery unless ifconfig eth down/up

If we can make No.3 above pinging successful, and try loopback network storm test again ?

Or if there is any other solution to set RMMI2 self-recovery after network storm?
