I've just started using VisualDSP and the BlackFin. My host computer is a 1.4GHz P4 running WinXP and using USB to communicate with the BF533 EZ-KIT LITE. Everything works, but it is really, really slow! - It takes about 6 seconds to run to the next breakpoint, even if that breakpoint is on the next line. - It takes at least 1 full seco

Hi all, I am trying to send the data out from the processor's(BF533) memory back to the "terminal screen"....through the UART. so what I did was I added "STDIO_UART.C" file from the STDIO_UART project to my "Audio"project

Hello All, I would highly appreciate any help regarding the following issue. I have a code written in C, which I intend to test on the Visual DSP++ 4.0 Simulator(Licenced version). The code is working fine when I select BF535 simulator as target but when I select BF533 simulator as target (which is the processor which I intend to use at later stage)the simulator gives the follo...

Hello friends Am using BF533 EZKIT board. The SPort1 is configured with internal tx clk. This means that i must be able to see the clk signal at TSCLK1 pin of the SPORT1 connector (pin 4). I have configured TSCLKDIV TFSDIV etc. But when i monitor using CRO i am unable to see any signal.What would have gone wrong? I also wanted to know if TCLK signal appears continuously at TSCLK pin or it...

Hello. I have a ADSP-BF533 EZ-KIT. Does someone have an example in C how to write/read in/from the flash memory? I studied the example Flash Programmer from the installation CD but it's to complicated for me and I don't get it how it works. Thank you.

Hi, I am new to ADSP-BF533. I'm working on a image processing project for video input on the Ez-Kit Lite board. Color video data are captured and stored in the BF533 external SDRAM in the following order: Cb0 Y0 Cr0, Y1, Cb2 Y2 Cr2, Y3, Cb4 Y4 Cr4, Y5, Cb6 Y6 Cr6.... where each Y, Cr and Cb is 8 bits. My problem is this: I want to do this kind of transferring: Cb0 Y0 Cr0, Cb2 Y2 ...

Hi all, I am using BF533 EZ-KIT Lite for my project on video processing. I have tried running the example codes( both C and ASM) for video input. The problem is I am getting a gray image on image viewer once I run the code and halt it. So please tell me where this image is stored(memory address)? and what should be the configurations of image viewer window. I also tried VideoEcho code...

Hi Group,   Sorry for posting this twice if I did.   I have an application in which I am using a BF533 to read a combination of user buttons to capture a frame of video, buffer it and display it back out to a video monitor.

Hi, I am working with an ADSP BF533 ez-kit and need to change the sampling rate to something quite low. The audio codec is AD1836 and its documentation pretty much only tells me that I can have sampling rates of 48 kHz or 96 kHz. I worked w/ a BF535 and I was able to change the

Hello people. I'm using BlackFin BF533 EZ-Kit with ISP1761 as a USB Host Controller. I could succesfully enumerate the internal root hub thanks to the documentation from NXP: AN10037, AN10054. (BTW, also found out some corrections to AN10037, such as writing HC Status Buffer Register) Well, I can send and receive tokens to the root hub, set its address and power the ports using the SetFe...

Does anyone know if there is a file size limit the the memory dump feature of Visual DSP when using the BF533? I'm using one of our own boards (not EZ-Kit Lite), along with HPUSB ICE for the emulator, and VDSP 3.5, but VDSP locks up (it seems) with memory dumps of any size. I can't find any reference to an upper size limit for memory dumps... And, does anyone know what's happened to bl...

Hi all, i have big problem with EZKit Lite BF533 & VisualDSP 3.1 If I declare big array in SDRAM and build projects I must wait too long (more then 2 minutes, depend to array size), then VisualDSP upload my code to EZKit. Did have somebody similar problem? Know

Hi all, I have some problems about the connection between JTAG header (2x7 pins) and ADI BF533. I had followed the schematics provided by ADI, in which construct the JTAG header from BF533 (EMU, TDO, TDI, TRST and TCK pins) using two ADG774ABRQ. However, I failed to connect my board to the USB ICE emulator, an error code 0x80048008 occurs. Did anyone try the ADI JTAG header connection bef...
