• BF534 sdram expansion

    customer is running out of SDRAM space on a BF534.  datasheet says can run up to 512M byte without any glue logic. Is it feasible to use multiple devices with the '534 since it has only one /SMS output?

    Currently we are using a Micron MT4816LC16M16A2…

  • BF534 Clock Buffer

    We noticed that the BF534 has a CLKBUF pin which is a clock output that is connected through a PLL and the CLKIN pin. We would like to use just a single 25MHz oscillator connected to the CLKIN and be able to use the PLL to get a 50MHz clock out on CLKBUF…

  • BF534 spurious stack overflow.


    We are having problems with a BF534 running a VDK-based C++ application. Basically, at (fairly rare) random intervals it crashes, locking up with a stack overflow. The system stack is currently 16k, and I have tried both 8k and 32k, and the frequency…

  • System Services Library BF534 (BRAEMAR)

    I am using the BF534 device and the SSL.

    I am trying to configure a callback on rising edge on pin PH12.

    I assume that the peripheral ID is ADI_INT_DMA1_ETHERNET_RX_PORTH_A

    Q1 Is that the correct Perihperal ID to use?  (How could it ever differ?)

  • BF534 l1 memory write problem


    I encountered a problem in L1 memory write, which was a hundred times slower than reading data from L1.
    Take a look at the code below. After adding "Filter_Buffer [j] = mul;" to the loop, the execution time of the loop increased by 8 microseconds,…

  • BF534 timer in WIDTH CAPTURE mode


      I'm using a BF534 with VDSP++ 5.0(update 7) and the SSL to  control a timer to try to capture the width

    of a single, one off pulse.

      I've programmed the timer with:

    static const ADI_TMR_GP_CMD_VALUE_PAIR   ambient_data[] = {

                // maintain…

  • BF534 SSL sets timer pin to output not input?


      I'm using a BF534 with VisualDSP 5.0 update 7.

    In the System Services Library adi_ports_bf534.c there's a routine called ad_ports_EnableTimer()

    and it gets called down the chain from my call to adi_tmr_GPGroupEnable().

    I have set up three…

  • BF534: My initialisation of SDRAM by VDSP fails on real target


      I'm developing a product for the BF534 under Visual DSP 5.0 update 7.

    I've started with the BF537 EZKIT.

      The code will eventually be too big for internal RAM and so I need to boot

    into SDRAM.  I have a small bootload code that loads into…

  • RE: Are there differences between the ADSP-BF537KBC-6A and ADSP-BF537KBC-6AV?


    The difference is in the recommended VDDINT voltage level. As long as you follow voltage specifications and provide adequate current according to the ADSP-BF534/ADSP-BF536/ADSP-BF537: Blackfin Embedded Processor Data Sheet (Rev I, 07/2010) you…

  • How FFT accelerator (FFTA) on ADSP-SC58x/ADSP-2158x is different as compared to ADSP-214xx processors / What are the major features of FFTA on ADSP-SC58x/ADSP-2158x ?

    FFT Accelerator on ADSP-SC58x/ADSP-2158x is a completely new design as compared to the FFT accelerator on ADSP-214xx processors. The major differences/features of the FFT accelerator on ADSPSC58x/ADSP-2158x are:

    • Unlike in ADSP-214xx, the…
