Hi,

I have this error, when using restool to create a dpsw with 13x interface (12x dpmac and 1x internal dpni).

MC error: No memory available (status 0x9)

Do i need to increase the DPAA2 MC memory (mcmemsize) ?

[yipingwang]

This is due to default configuration of DPSW, the number of FDBs being 8.

If you limit the number of FDBs to 2, you will be able to create the DPSW with 63 interfaces.

Command : restool dpsw create --num-ifs=63 --max-fdbs=2.

Hello,

You forgot to mention in your previous answer, the following:

ip link add dev br0 type bridge vlan_filtering 1

I needed to put the vlan_filtering 1 in there otherwise it does not work and we get an error.

If you look here: DPAA2 Switch driver — The Linux Kernel documentation

The minimum number of FDBs should be at least equal to the number of switch interfaces. This is necessary so that separation of switch ports can be done, ie when not under a bridge, each switch port will have its own FDB.

So I do not understand how i can put 2x FDB , i need a minimum of 13x FDB (since i have 12 DPMAC + 1 internal DPNI ) for the DPSW that i want to create.

Please can you help me here ? If i put 2x FDB , i do get an error :

fsl_dpaa2_switch dpsw.0: The number of FDBs is lower than the number of ports, cannot probe

[Fa007]

I am using the restool command : 

ls-addsw
  

[yipingwang]

I used LSDK 21.08 pre-built images, and didn't find any problem to run the following command.

root@TinyLinux:~# ls-addsw -i=13

Hello,

You won't have the problem with the LSDK 21.08 as it is using an older MC firmware.

I am using NXP LLDP with MC version 10.38.0. Please try with that version.

mkdir -p yocto-ws && cd yocto-ws

repo init -u https://github.com/nxp-qoriq/yocto-sdk -b mickledore

repo sync --force-sync

Thanks.

[yipingwang]

Please use the following command.

~# ls-addsw -i=13 --max-fdbs=2

Please refer to my attached console log.

[Fa007]

Hello,

The command you provided did not work.

You can tell that because the ethx print did not appear after you executed the command...

[yipingwang]

Please address your current problem in a new thread.

[Fa007]

It should show the following output:
Created ETHSW object dpsw.0 with the following 13 ports: eth10,eth11,eth12,eth13,eth14,eth15,eth3,eth4,eth5,eth6,eth7,eth8,eth9
