After studying chapter 7 of the Hardware Reference Manual at:
and the AD7606 Spec Sheet
I am using the BF548 EZ Kit as a reference design for a BF547 based system I am designing. On page 118 of
what is the point of the jumper at pins 1 & 3 at…
I need the EBIU settings for the ADSP-BF547. The settings that spread sheet shows does not include settings for the ADSP-BF547.
I am using the schematics at:
as a reference to design a system based on the ADSP-BF547. I would like to have the debug capability of Boundary Scan. Section C3 on page…
One of my customers asked about using the FFT function of BF547.
When using FFT function (cfftf, cfftrad4) provided by VDSP ++ Library while implementing FFT with ADSP-BF547 DSP, phase angle error occurs more than 1 degree.
FFT function driven…
The datasheet states that "Use of an internal voltage regulator is not supported on automotive grade and 600 MHz speed grade models." for the BF547. However, the internal regulator works fine in our ADSP-BF547-KBCZ-6A, without the ability to adjust…
We are testing a new board based on BF547. As a base we use the uboot for the ADI BF548 EZ-Kit board
Our uboot steady hangs on:
CPU: ADSP bf547-0.2 (Detected Rev: 0.4) (spi flash boot)
Board: ADI BF548 EZ-Kit board
I call the function memcpy several times in a row.
after few calls the processor crashes. the length off the buffers I copy is fixed.
I can see,in the disassembly window , that only before the first call , the compiler assign the value off the buffer…
We have developed Blackfin based board using BF547-Rev04.
At the moment we face strange probably hardware issue.
Let me share few details
- The DDR routing due to a PCB mistake is not perfect now so we had to
reduce the SCLK to 75 MHz
- We use toolchain 2011R1-RC4 and uClinux 2011R1-RC3
- The DDR routing due to a PCB mistake is not…
