Hello, I am trying to run a project created for SHARC processor. I have a C function that is called from an assembly routine. When I run the project the emulator stops at the first line of the C function and outputs this funny message: "target halted due to software breakpoint but no breakpoint found at address..." I know that the problem is related to interrupts. When I click on F11 (ste...

Analog Devices DSPsHi, I'm in the same position: I work for a small company with an open-source mentality that balks at paying thousands of bucks for the VisualDSP toolset. So when we wanted to make a product with a DSP, I chose the ADSP-2181, used the old command-line assembler that came with the EZ-KIT, and made my own debugger that connected through the DSP's IDMA port. The 2181 is a pret...

Hi, I am trying to call an FFT library function from assembly code. I am working with ADSP 21396 processor (SHARC). I picked _cfftn_nonSIMD. I've tried using the SIMD version but it doesn't work. Anyway, I don't have to use it since the FFT calculation is not under tight timing constraints. The problem with the nonSIMD version is that it doesn't give correct results for 4096 points. _cfft128...

Hi, Has anyone ever managed to use the onbard USB-based debugger interface of the EZ-KIT Lite to debug an other board ? I am wondering what it takes to make this work. Maybe just directly using the TDI TDO TCK TMS TRST lines of the EZ-KIT Lite ? There might be a kind of protection though ? or maybe not ... ? ADI provides the schematics for the EZ-KIT Lites, but of course, the USB part...

I don't know how your fifo is connected -- but if it is connected in parallel, you just need to connect the fifo output lines (FIFO[11..0]) to the highest portion of the data bus -- that is D[31..20] if you use a Sharc -- and tie the lower end of the data bus to GND via a read-strobed bus
