C6472 CSL DUAL EMAC EXAMPLE

HI,

I recently began working on the C6472 EVM board and am running the CSL EMAC _DUAL_EMAC example. This works fine for me but am actually trying to do the reverse of the example in that I am trying to receive data in through one EMAC and send out the other. It is currently working in sending data out and then reading in. This is fine but attempted to supply data from external source but doesn't seem to receive any packets. I am probably just doing something incredibly stupid.

Does anyone have experience of this example,. I thought that it would be straight forward ,

have tried replacing receivefilter from DIRECT to ALL in DUALSENDRECEIVE().

Am supplying correct packet size of 1600. Any ideas anyone?

    Hi,

    still having problems to receive data with C6472 EMAC CSL. Can anyone tell me what causes a HWRX interrupt?

    Also looking to generate data externally to send to C6472 but having problems with correct packet structure. any ideas?

    Hi, apologies again I know I've recently posted same question.

    Working with CSL Dual EMAC example and is working fine. Packets are being sent and received from Eth1 to Eth 0 over external cable.

    I just cant seem to be able to recreate receive packets from ext source. Sniffed packets being sent from eth1 to eth 0 using wireshark. consists of mac address and payload. But when try to supply this same data from smartbits directly to eth0 the Hw0RxInt is not being fired. Am I doing something really stupid?

    Have sniffed the packets coming from smartbits and is identical to that being sent from eth1. Any help would be great! getting desperate!!!

    Jay,

    I went ahead and merged these threads.  The question thread has been forwarded to an individual that has more knowledge in this particular area and hopefully he will be able to address it soon.  Please feel free to continue to append to this thread instead of creating new threads.

    Best Regards,

    Chad

    Jay,

     

    What version of CSL do you have?  Have you tried the latest CSL: http://software-dl.ti.com/sdoemb/sdoemb_public_sw/csl/CSL_C6472/latest/index_FDS.html  which includes an example?  Typically, most customers use the NDK examples that come along with the SDK and EVM.  The NDK provides a complete IP/UDP stack.  You can download at:  http://www.einfochips.com/TI/EVMC6472_SDK_Setup_4_0.exe.  This also contains the latest CSL package.  I would suggest trying that out.  I'm not familiar with the dual emac example.  Have you looked at the RX statistic registers for good and filtered frame reception when trying to send via smartbits?
