Hello,


I have changed my fmc150 stellar ip star removing the waveform memory from DAC. Now i want to conect the ouput from ADC to DAC, which is easy to do in Stellar Ip.
Now i'm having a problem because i want to send a "copy" from the data that is passing from ADC to DAC, to zedbhost_if. I want to use the existing router, so can i just connect the output from ADC to both DAC input and router input?

I have another problem with the FMC15xAPP that i have modified. I programmed the board with the go *.bit file and everything went okay, the autonegotiation was okay too, but when i run the APP it always say "Could not open device 1000"


I already tried your APP and your bit file and it shows the samething. What is causing this issue?

Thanks

Hi,


How did you connect the ADC to the DAC? I don't think that is easy to do, they have different rates and resolutions, did you match those and get it working? You should focus on that first once that is working sending to host is easy because it is already done. You send a trigger that starts capturing to a FIFO that gets read to the host. Streaming the ADC data to DAC requires matching the rates and resolution., if you just want to capture and repeat that is easier, just wire the adc data to that waveform repeat entity and pay attention to clock domains for commands and data.

So you haven't been able to run the reference application and bit file as provided?


Regards,
Luis

I just removed the waveform memory from the vhdl code and in Stellar IP i conected the output of ADC to the DAC input.


I have tried to run the APP many times, and today it worked only one time.... I have already run it several times in other days and it worked, but now i'm having that error. I followed the doc explaining it. I used the jumpers in my zedboard like in the figure, but when i do it it says "done bit can't go high". If i used the jumpers in programming mode i'm capable of program the board, but then when i run the APP it says "Could not open device 1000"

That won't work, because the two devices are sampling at different rates...

There might be an error in the figure for the jumpers, follow the description in the text not the picture. Make sure you are using the bit file provided by 4dsp not the one you built. Also post your console output.

I thought that after remove the wfm, i just have to take care with DAC and ADC frequencies when using the FMC15xAPP.


I already did everything as the doc say, with your files and the same problem occurs. I attached a photo to see.
