Are there any blackfin experts here looking for a challenge ? Over at Eevblog forum we have managed to hack the 50 Mhz DS1052E Rigol scope to the faster 100Mhz DS1102E just by changing the serial number. But on some occasions this has not worked and we need to reprogram the boot flash from a copy that is from a working scope. The problem is nobody there seems to know the blackfin processor ...

Hi there, I am intending to design a PCB for the Blackfin 531/2/3 dsp. I have not any experience in PCB design when it comes to such a high performance processor before, and I would like some help and advice on it. It will need to interface with an omnivision camera module. My concerns are to do with the chip's packaging, and th

HI, I would like to boot the blackfin via the spi interface and I am not sure how to get the initial code into the eeprom. Does this prom have to be programmed via an external programmer or is there a way to get code into the spi eeprom via another method? Regards, Jeff

Hello everybody, I have two problems: I bought a EZ-KLite Blackfin 533 and I want to use it with a version of VisualDSP++ that I bought for a Shark processor. However I don't know if it is possible to use the 32 bit version of Visual DSP++ for Blackfin, I think that i

Hi All, I would highly appreciate if any one can answer my query. I have written a small program in C to check the cycle consumption for different operations in Blackfin (BF535) I am using the demo version of Visual DSP++ 3.5 simulator for this purpose. The code which I have written is as follows... void main(void) { long int a,b,i1,i2,i3,i5,i6; a=4; b=2; i1 = a+b; i2 = a*...

I've been evaluating the Blackfin using the EZ-KIT and a JTAG ICE. Looks good on paper, but I have run into a problem. MemDMA to L2 SRAM doesn't seem to work. DMA to other destinations works, but not L2. It partially completes and then locks up the DMA engine. Is this a k

Hi Group- My application is running on a Blackfin BF532 mainly collecting analog signal samples and doing some simple processing on a per- sample basis. The data rate is 4M SPS so I'm digging for any speed optimizations I can get. I've observed a situation in which _adding_ lines of code makes the execution time _decrease_! Here's my code: #define BUFFER_SIZE 32 static long gB...

I'm using the VDK for a blackfin project. Its not clear how to configure the core and system clock. The kernel tab has a nice "clock frequency" parameter that you can set but I can't find any explanation of what it does with this. How does the setup code know

Hello out there, I just wondered whether anyone of you has already solved the problem I am currently facing. I want to implement a multi section biquad iir filter on a Blackfin DSP. The problem with the filter routines that are provided within VisualDSP are: iir_fr16(): ----------- The function normalizes the a0 coefficient to 1. Since a1 and a2 also must be 1 or less in fraction...

Hello everybody. I have a problem with blackfin 533. I want to use the video input example but it doesn't work. The problem is that it doesn't enter the ISR routine. I use Visual DSP++ 3.5 with blackfin 533 ezlite . I don't know what to do, the PPI register is correctly

Hi all, Does anyone know if it is possible to use the VisualDSP++ software that comes with a Blackfin ezkit with a custom designed Blackfin-based board? The reason I'm asking is that I'm planning to design a Blackin based board with hi-speed ADCs and DACs for processing modem

Hi, I'm Marko from DSP research group of Institut Teknologi Bandung Currently I'm tackling with the implementation of a statistical signal processing algorithm on Blackfin BF561EZ. I just started working with the machine thus, you can consider me as a newbie. In my work, the machine needs to handle calculations with real numbers. The problem is even the algorithm is successfully compiled, the m...
