    Hi, DSP2 has no MDIO connection to the switch so it will not get configured, that was the issue. So you need DSP1 to configure the switch and remove the switch config from the NDK running on DSP2. In File "ethdriver.c" you need to tweak the function _HwPktPoll as follows (for...

    Alex Khusidman
    Hi, I'm designing a PCB with 4 C6474 DSPs. Is it possible to use constant 1.2V as core voltage for C6474 DSPs and share core power supply between all DSPs on board rather than dedicating an adjustable power supply to each DSP? If it is possible, what would be the estimated increase of power...

  • Forum Post: Re: C6474 SYS Clock vs FSYNC Clock

    Tom Johnson16214
    There is no requirement for maximum skew between these clock sources. The only requirement is for frequency coherency. Either one of the clocking solutions proposed will be acceptable. Skew matching is not needed between the SYSCLK and FSYNCCK signals.

    A sender and a receiver share the ownership of a shared memory buffer.The data itself doesn't be transfered,but the ownership of the buffer changed from sender to receiver.The sender pass a pointer which point to the shared memory to the receiver,and then the recevier could use those data in the...

    Kaiqi Yang
    Thank you for your reply!And another question,can EDMA3 transfer be parallel?For example,while Core0 is using channel 0 to transfer data to Core1,Core 1 uses channel 1 to transfer data to Core2.

    Kaiqi Yang
    EDMA3 has 6 queues and 6 EDMA3TCs,does this mean there could be up to 6 transfers at the same time cause for every Q/TC there could only be one transfer at the same time?

    Thank you for your reply!I'm using C6474 and I want to get to know the biggest data transfer rate taht EDMA3 could reach,so the number of simultaneous transfers really matters,right?

  • Forum Post: Re: Puzzled by EDMA3

    Kaiqi Yang
    I mean is the total data rate of EDMA3 equals to all 6 TCs put together?

    From sprug11,we konw that the maximum value of ACNT is 65535 and valid values for SRCBIDX are between –32768 and 32767.But when I set ACNT to 65535 and set BCNT to 4,what the value of SRCBIDX should be?

    Ali, I beleive you have one of the TMS320C6474 Mezzanine EVMs produced by Spectrum Digital. You should discuss this with your FAE. If it is a hardware problem, the board may need to be RMA'ed to Spectrum Digital. Tom
