SJA1110 Linux DSA driver

yangjinzhuang — Fri, 08 Nov 2024 07:20:00 GMT

Hello,

Can you give me the CLI command to set SJA1110's port mode base on SJA1110's Linux DSA driver?

I can see that it provides support for other features of the switch like VLAN and PTP, but can't see how to config port-mode in the Linux-BSP UM file.

Example of network interfaces when the SJA1110 DSA driver is loaded:
root@s32g274aevb:~# ip addr show
...
7: pfe2: <BROADCAST,MULTICAST> mtu 1504 qdisc noop state DOWN group default qlen 1000
link/ether 00:01:be:be:ef:33 brd ff:ff:ff:ff:ff:ff
8: enet_p1@pfe2: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 00:01:be:be:ef:33 brd ff:ff:ff:ff:ff:ff
9: enet_p3@pfe2: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 00:01:be:be:ef:33 brd ff:ff:ff:ff:ff:ff
10: enet_p4@pfe2: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 00:01:be:be:ef:33 brd ff:ff:ff:ff:ff:ff

Hello @yangjinzhuang,

Good to read you again. About your question, there are no specific terminal commands to interact with the SJA1110, there are several software abstraction layers between the SJA1110 driver and the command line utilities. With that said, I recommend you checking the Linux kernel documentation where you can see the following [https://docs.kernel.org/networking/dsa/dsa.html]:

In this case the "switch" mentioned in the docs, is the SJA1110. This means that you can interact with it with the generally supported network commands.

You can learn more about them by using the "--help" argument, for example:

root@s32g399ardb3:~# ip --help Usage: ip [ OPTIONS ] OBJECT { COMMAND | help } ip [ -force ] -batch filename where OBJECT := { link | address | addrlabel | route | rule | neigh | ntable | tunnel | tuntap | maddress | mroute | mrule | monitor | xfrm | netns | l2tp | fou | macsec | tcp_metrics | token | netconf | ila | vrf | sr | nexthop | mptcp } OPTIONS := { -V[ersion] | -s[tatistics] | -d[etails] | -r[esolve] | -h[uman-readable] | -iec | -j[son] | -p[retty] | -f[amily] { inet | inet6 | mpls | bridge | link } | -4 | -6 | -I | -D | -M | -B | -0 | -l[oops] { maximum-addr-flush-attempts } | -br[ief] | -o[neline] | -t[imestamp] | -ts[hort] | -b[atch] [filename] | -rc[vbuf] [size] | -n[etns] name | -N[umeric] | -a[ll] | -c[olor]} root@s32g399ardb3:~# bridge --help Usage: bridge [ OPTIONS ] OBJECT { COMMAND | help } bridge [ -force ] -batch filename where OBJECT := { link | fdb | mdb | vlan | monitor } OPTIONS := { -V[ersion] | -s[tatistics] | -d[etails] | -o[neline] | -t[imestamp] | -n[etns] name | -c[ompressvlans] -color -p[retty] -j[son] } root@s32g399ardb3:~# ifconfig --help Usage: ifconfig [-a] [-v] [-s] <interface> [[<AF>] <address>] [add <address>[/<prefixlen>]] [del <address>[/<prefixlen>]] [[-]broadcast [<address>]] [[-]pointopoint [<address>]] [netmask <address>] [dstaddr <address>] [tunnel <address>] [outfill <NN>] [keepalive <NN>] [hw <HW> <address>] [mtu <NN>] [[-]trailers] [[-]arp] [[-]allmulti] [multicast] [[-]promisc] [mem_start <NN>] [io_addr <NN>] [irq <NN>] [media <type>] [txqueuelen <NN>] [[-]dynamic] [up|down] ... <HW>=Hardware Type.

Hello, I have read the three posts you posted. Can you provide the download address of dsa for sja1110? I would be very grateful if you can provide some other tips on compiling or using dsa
