Simultaneous operation of PCI and GbE on C6452EVM

 

Does C6452EVM support simultaneous operation of PCI and GbE?

 

  • The C6452 does support both ports operating at the same time. The SGMII pins are not shared with other functions, so there would be no physical limitation to using PCI at the same time.

    I do not have an EVM for the C6452, but as long as both ports are made available on the board then they should both be available for use simultaneously.

    Do you have any reason to doubt this capability on the board, or was the question more related to the DSP's capability?

  • This question came from C6424EVM configuration actually, and C6424EVM's PHY chip output falls into Hi-Z when selecting MII. (This is natural manner due to PCI and MII pins are multiplexed.)

    Since I don't have detail information of C6452EVM, I was wondering if simultaneously PCI and SGMII operation can be realized or not on C6452EVM. (and also same question on DM648EVM)

  • Perhaps you can post this request on the internal forum where you may get access to internal documentation to help your research?

  • Thanks for your advice, and I'll access to internal site for further investigation required.
