Thanks for the documentation of the DRAWS Hat! Several questions are answered here.
Thanks, Mike WF8O

I'm sorry Jonathan,
You did show the showudrc and it shows some of the modules, and the /boot/config.txt. If could show all the modules the sudo lsmod and the /etc/modules file that would be interesting. Thanks - Frank - K0FEI

Hi Basil,
Just adding the lines to /boot/config.txt didn't get the tlv modules to load and I could not see the sound card. If I put those lines before the drtparam=audio=-on then aplay -l said there is no sound card found. In the Stretch version there is a module udrc loaded. What does that do and do we still need it? I am presenting my 3d printed case for the draws hat on a Pi4 at the Tech Connect 285 club the first Saturday in September and would like to tell everyone how great the product is. We have a lot of SOTA folks (Colorado is SOTA heaven) and the draws hat is one of the smallest interfaces available. The following Saturday we will be having our annual picnic on a SOTA peak and showing off equipment. The long and short of it is you have a show stopping problem and it would appear you can not duplicate it. I am not the only one who is having the problem. I know what I would do if it were my product. It would not be to blow it off until after some hamfest more than a month down the way. Frank - K0FEI

Hi Jonathan,
Could you look at a couple of things and tell me what you are seeing. 1. Could you enter sudo lsmod. That should display a list of kernel modules loaded. 2. Could you cat /boot/config.txt to type out the config.txt file. 3. Could you enter the nx7nix/bin/showudrc.sh. Its a lot of stuff but it tells pretty much the story. 4. Finally could you cat /etc/modules and get a list of kernel modules that are being loaded. Thanks Frank - K0FEI

Stretch is the best path for Pi 3 and Pi 2. If you have a Pi 4, you will need to use Buster and the edit that Basil lists. Now that the DRAWS™ support is directly in the Buster kernel, it is configuration to activate it. We may put out some images specific to some application groupings on top of Buster with DRAWS™, but they will start on top of Buster. Pi 4 is still leading edge at this point.

Hi Jonathan,
Are you using the hat with the gps antenna on the side with the sockets or on the back of the card? Thanks Frank - K0FEI

If you use a Raspbian image & add these lines at bottom of your /boot/config.txt file: dtoverlay=draws,alsaname=udrc force_turbo=1 DRAWS drivers will be running & your DRAWS hat will be recognized. There is no upgrade path from draws_image13 which uses Debian stretch to the latest Raspbian distribution which used Debian buster. There will be a new image posted sometime after the Pacific Northwest Summer Gathering in the last part of September. In the mean time either use draws_image13 and don't do an upgrade or use the latest Raspbian image. /Basil n7nix Jonathan Visser via Groups.Io <n9tjx=yahoo.com@groups.io> writes:

Why not just simply release a Debian "draws.deb" package that enablesIn the latest kernels supported by Raspbian (4.19.58) DRAWS hat required drivers are in the main stream Linux kernel. You still need to load the overlay in /boot/config.txt but other than that, thanks to Anna, DRAWS is supported in the latest Linux kernel. As far as the DRAWS boot images are concerned they were provided as a convenience to provide a distribution that supports A LOT of commonly used amateur radio Linux software. It would be nice if all those programs were Debian packages but someone would have to step up & do that work. /Basil n7nix

SQL or COR is normally an open collator output from the Radio. Yaesu changed it to an I/O on some models. TNC Cable makers and some TNCs ship with cables that have pin 6 removed for this reason.

I was able to successfully see the sound card when completing the steps that Mr. Hays gave. The issue I have is going onto the n7nix scripts. After running the ./app_config.sh core, I no longer see the UDRC sound card. This was discovered late last night and I have not had a chance to troubleshoot these issues. For those having issues did you continue run that script before testing the sound card? I will try to troubleshoot soon and open a separate thread for the issues with the n7nix config script.
