• ADSP- BF536 RTCVDD Power Consumption

    ADSP-BF536 - RTC Power Consumption - solution for UL certified application...

    In order to get a UL certification, we designed in a 1K series resistor to the RTCVDD pin. This value resulted from the requirement, that according to UL, a battery must not…

  • power-up sequencing for giving 3.3V and 1.2 V input supplies to ADSP-BF536/7

    I am using a dual supply LDO regulator with power-up sequencing
    for giving 3.3V and 1.2 V input supplies to ADSP-BF536/7. This regulator has a
    power up sequence and gives 3.3V o/p first and 1.2V follows. Do you see any
    problem with this…
  • How to use HTTP_Server in BF536?

    Hi!

    How can I port the Web server example in the VisualDSP++ to my BF536 board? the example is originally port for BF537.

    I have refered the EE-315 document to  change the PHY driver for my PHY chip;

    then I open the Web server example project grou…

  • BF536 EMAC_TX_DMAUND

    Hi,

    I'm having a difficult time with the BF536 DMA. I currently have a VDK based VoIP-like application which streams RTP out of the EMAC at 1 packet per 10ms. So it's 92 byte UDP plus the ethernet overhead.

    In a 30-second streaming test I notice…

  • changing from bf536 to bf537

    We have recently changed our processor from a bf536 to a bf537, and encountered some difficulties, largly in addressing external memory .  I am told there may be an initialisation file in the environment application which will require changing.  Does anyone…

  • Blackfin BF536 SPI Booting Failures

    I have a Blackfin BF536 processor set up to load the program from an external SPI memory chip. A test stand program is initially loaded on the memory chip, and the Blackfin boots the program from the memory chip with no problems. However, the regular…

  • BF536 MAC DMA acting "funny"

             We are using Blackfin CPU ADSP-BF536BBCZ-4B rev 0.3 and we are having problem with MAC DMA. For certain packets the EMAC_RX_STAT register has the following value (after the packet is received):

    0x82041000 which means that packet length is 0, the frame…

  • Recompiling libetsi library for BF536

    Hello all,

    I am using VisualDSP++ 5.0.10.0 and I need the ETSI library functionality for my Blackfin 536 project. However, there are only libetsi532*.dlb and libetsi535*.dlb files in the Blackfin/lib directory.

    How can I rebuild this project for the…
