Re: possible DRAWS hardware failure.

Basil Gunn

From your description your system is either not loading the draws driver
or you have a hardware error.

Please send the output of to my personal email address.


I ran your suggested procedures and I am still where I was when I
started. When I run FLDIGI, after doing all the prerequisites for
shutting down DIREWOLF and and running ./ax25-stop , I still cannot
select a sound card from the fldigi audio setup menu. To select the the
codec from the fldigi audio set up I must have #dtparam=audio=on
commented out in the config.txt file. With dtparam=audio=on commented
out with the # symbol I can then select urdc: - (hw:0,0) , not urdc: -
(hw:0,1) for capture and urdc:-(hw:0,0) for playback. This result is
what you said enumerates with dtparm=audio=on commented out, only hw 0,0
will enumerate.

When following the new draw "getting started doc "DRAWS Raspberry PI
image" from the wiki and run "aplay-l I" do not get the same results
shown in the example of the doc.

This what I see:

I have tried re formatting the micro sd card, changing sd cards, re
burning the image, changing the RPi 3 B+ to a different RPi B+, powering
the RPi/DRAWS board from 12 volt supply. I am out of ideas and because
of the anomaly in the results from aplay -l I think the problem it is a
hardware failure of the DRAWS Board.

If you have any suggestions I am ready to try them.
