I have a customer asking the following question. Please advise what they need to do to get running. Thanks!
I’m having trouble running the AM3352 board in bridge mode:
[root@alarm alarm]# brctl addif br0 eth0
[ 606.819494] br0: port 1(eth0) entered blocking state
[ 606.824613] br0: port 1(eth0) entered disabled state
[ 606.839543] cpsw 4a100000.ethernet eth0: failed to initialize vlan filtering on this port
[ 606.856116] br0: port 1(eth0) entered blocking state
[ 606.861167] br0: port 1(eth0) entered disabled state
[ 606.874195] cpsw 4a100000.ethernet eth0: failed to initialize vlan filtering on this port
can't add eth0 to bridge br0: Invalid argument
Bridging is a critical feature for our application since our firewall is designed to be transparent. I’m also running the same application on an Intel platform using the same distribution of Linux, i.e. Arch Linux and it works like a charm. I believe the problem with the AM3352 platform is the AM335x CPSW.
