NDK - Jumbo Frames support on the C6678

Hi,

I have seen that NDK2.0 support Jumbo frames and the phy on the EVM6678l also support it, does the C6678 internal eth. switch support it? will there be a C6678 example/driver?

Thanks,

HR

    HR,

    Yes the 6678 is supported through the MCSDK.  You can download that here:

    http://software-dl.ti.com/sdoemb/sdoemb_public_sw/bios_mcsdk/latest/index_FDS.html

    As far as jumbo frame support goes, this is supported by the NDK core (out of the box in NDK 2.0, but a rebuild is required for NDK 2.0.1 and up).  I am not sure if the 6678 driver (that's shipped in the MCSDK) supports jumbo frames or not, but I would think that it would.  I can double check for you.

    Also, here are some more links on jumbo frames in case they help:

    Hi Steve,

    I'm using the C6678 MCSDK but somehow I haven't seen the jumbo frames support, It will be great if you can check it,

    Many Thanks,

    Hi HR,

    I spoke to someone on the MCSDK team.  Unfortunately, it looks like there is not any support in the 6678 driver.

    I know that the SDK ships the driver source code, so you may be able to add it and rebuild the driver.

    Hi Steve,

    I will to change the driver, I will post a question on the C6678 to see if adding the jumbo packets support is in the driver road map,

    Thank you very much,

    HR
