Original question:

TDA4VM: how to configure CPSW9G vlan

TDA4VM: TDA4VM

Part Number: TDA4VM

Hi,
we use TDA4VM, QNX+RTOS, based on SDK8.0
Now we test on QNX console that:
cpsw2g(which from doc I think that it connect to A72 core, QNX system) with vlan function work;
but cpsw9g(which from doc I think that it connect to R5F core, FreeRTOS system, connect to QNX with IPC) with vlan function not work.
Can you give some advice or a patch to make cpsw9g work well?
We have a requirement of 5 vlan and IP.
Thanks.

    Hi,

    The VLAN support for CPSW9G virtual driver is available in the Processor SDK QNX 8.1 release. The SDK 8.0 release does not have this supported fully. 

    In the 8.1 release, a special command-line option called "joinvlan=" is provided to support this. More details can be got by running "use devnp_cpsw9g.so" command on the QNX prompt.

    For example, if VLAN 5, 6, 7, 100, 101 are needed, then the driver must be started with --> io-pkt-v6-hc -d cpsw9g joinvlan="5;6;7;100;101" -p tcpip

    Hope this help.

    Thanks.

    Hi Praveen,

    Thank you very much for your information.

    Since our project is using SDK8.0 as base code, now if we upgrade to SDK8.1, it will
    cost extra time and work. So, Is there a possible that provide a patch to support vlan
    feature in SDK8.0 ?

    Thanks.

    Hi,

    Providing a patch release is not possible at this time as we are currently busy with our SDK 8.2 release activities. Our suggestion would be to compare the code difference b/n the 8.0 & 8.1 especially the DEVNP driver source in the Processor SDK QNX.

    Thanks.
