Radioberry not working properly

[Jan Jaeger]

Hi,

I have a radioberry from AURSIINC (CL025), and am having trouble getting it to receive signals.

It does not respond for quite some time after the gateway is loaded.   

The gateware load succeeds, but the first communication over the /dev/radioberry does not work for 15-20 minutes.  It simply does not respond.

GPIO PIN 25 (Data available) only becomes high after that time, and the icoctl to read the version only returns the right version after that time. 

Once it is in this state it will actually read data from the device, but (I think) it reads at a much to slow rate.   Also, the contents of the data that is read is mostly zeros. (Frame header and counter at the start of the frame seem ok though)

Currently using an RPI5, but getting the same results with a RPI4.  Current running a 6.6 kernel, but getting the same issue with a 6.1 kernel.  My guess is that the issue is related to the radioberry board.

The FPGA seems ok, as I can load the code, and it eventual does something.

I curerntly suspect the issue to be with the AD9866 or the maybe X400 clock.

Any suggestions are appreciated

Which software do you use.If its pihpsdr you have to switch off gpio when compiling.
