  1. If I check the logs, it says "could not detect attached switch" and "couldn't create dsa switch instance (error -22)" but then plugging into either port 1 and/or 6 on eth0 works (in a switched fashion). > grep mvneta /var/log/kern.log /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 2.757054] mvneta f1030000.ethernet eth0: Using device tree mac address 00:50:43:84:25:2f /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 2.766103] mvneta f1034000.ethernet eth1: Using device tree mac address 00:50:43:0d:19:18 /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 2.775131] mvneta f1070000.ethernet eth2: Using device tree mac address 00:50:43:25:fb:84 /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 5.870134] mvneta f1030000.ethernet eth0: [0]: could not detect attached switch /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 5.877581] mvneta f1030000.ethernet eth0: [0]: couldn't create dsa switch instance (error -22) /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 5.921177] mvneta f1030000.ethernet eth0: [0]: could not detect attached switch /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 5.928620] mvneta f1030000.ethernet eth0: [0]: couldn't create dsa switch instance (error -22) /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 8.276781] mvneta f1030000.ethernet eth0: configuring for link AN mode fixed /var/log/kern.log:Feb 12 08:36:58 localhost kernel: [ 8.289888] mvneta f1030000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off How do I get DSA up and running? Would you happen to have a primer on DSA ? Seems that at least the marvel bit is compiled in. > uname -r 4.4.1-marvell > lsmod Module Size Used by marvell_cesa 26406 0 dsa_core 15184 0 Also, the ports on eth0 only work in one mode, GbE, no flow control. Tested alternate modes: # 100mbps Full Duplex Connected, no traffic Half Duplex Connected, no traffic Full Duplex, Flow Control -No Connection- # 1 GbE Full Duplex Connected/Working Full Duplex, Flow Control -No Connection- However eth2 will work in 100mbps perfectly fine. I haven't yet installed an SFP yet so I can not say there, whether that affects the operation of the eth0 ports (1-6). Maybe it is missing the driver / I am missing the driver as you say Igor -- And once I have that installed it will Auto-negotiate properly? Ideas ? Suggestions from here? Thanks! -Eric
  2. I was hoping someone using a clearfog board could help me out with a working config for the switched ethernet ports on the clearfog board, to be able to access them as individually as possible as the hardware and linux allow for. Anyone with a Clearfog board by chance? Thanks! -Eric
