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

Thanks,

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.
Provide the output of showudrc.sh describing what you did doesn't work
for me.

lsmod | grep -i tlv320*

snd_soc_tlv320aic32x4_i2c 16384 27
snd_soc_tlv320aic32x4 40960 1 snd_soc_tlv320aic32x4_i2c

snd 73728 14 snd_compress,snd_timer,snd_soc_tlv320aic32x4,snd_bcm2835,snd_soc_core,snd_pcm

This works with the latest version of Raspbian which uses this Linux
kernel

uname -r
4.19.57-v7l+

If you do not see the udrc driver enumerated:

aplay -l | grep udrc

card 1: udrc [udrc], device 0: bcm2835-i2s-tlv320aic32x4-hifi
tlv320aic32x4-hifi-0 []

then you are not using the latest Raspbian image it's that simple.

Also Beta image 13 works as long as you do NOT do an upgrade.

It would not be to blow it off until after some hamfest more than a
month down the way.
It's 2 weeks a way, thanks for your concern.

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.

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.

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

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.

Use the latest Raspbian image that supports Debian buster and add these

There is no upgrade path from draws_image13 which uses Debian stretch to
the latest Raspbian distribution which uses Debian buster.

This is because the transition of the DRAWS driver support to be in a
native Linux kernel. 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.

In 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.

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.

Second that notion.  There is  a lot of what I consider unwanted fluff in this image since I don't care about packet radio.  I would really like to have a clean image with only the necessary drivers and such and then I could install my own programs, and select the HF programs that I want to use.  So perhaps a "minimal" image that gets the DRAWS functioning properly on the RPi??

Hi Mike,
I can confirm that I am powering it via the 12 volt plug. When you write up your clean install, please could you specify which version of the buster image you use....
