Can I use eth0 and eth1 on K2H with both NDK running?

- EVMK2H(66AK2H12) with using TI RTOS

- ccs version : Version: 6.2.0.00050

- NDK : ndk_2_24_03_35

- PDK : pdk_k2hk_4_0_2

I am still confusing that below scenario is possible?(really sorry for bother you :<)

- NDK running with dhcp on eth0 at DSP core_0 and NDK running with dhcp on eth1 at DSP core_1

If above scenario is possible, I could 'ping' both Ethernet port(eth0 and eth1)

    Hi,

    I've notified the ethernet experts. Feedback will be posted directly here.

    Hi,

    The NDK runs on top of the NIMU driver, the NIMU driver runs on core 0, it can be changed to run on other cores (see e2e.ti.com/.../370255). But NIMU driver doesn't support simultaneous multicore operation (e2e.ti.com/.../167588). Those discussion applies to K2H as well.

    There is PA multicore example under PA driver, this doesn't use NDK.

    Regards, Eric

    Hi Iding.
    Thank you for your reply.
    Unfortunatly, the two pages you've mentioned don't exist.("Unfortunately, the page you've requested no longer exists. bla~ bla~)
    Anyway, If NDK cannot run on multicore at simultaneously, How about below scenario? Is it possible?

    -NDK running with dhcp on "eth0" at "DSP core_0", PA running on "eth1" at "DSP core_0".
    : I've tested above scenario. However, I've met the error message "QPPI initialization fail~~".

    To sum up, I would like to use both eth0 and eth1. How could I solve it?
    Is there another solution except using PA.
    (PA solution uses both eth0/1, but it cannot run NDK. Therefore, the DHCP and ARP feature is not available.)
