Re: Buster Image with DRAWS software

Edward Seeliger
 

I apologize - I deleted my message that started these comments once I realized the .xz file was compressed. I used 7-zip to uncompress it (internet search told me how). Etcher loads the resulting .img file without errors or  problems and it does boot on my RPi 3 B+ with DRAWS attached. aplay -l shows the URDC card. Using N7NIX's update process (prog_refresh.sh) updates the scripts and shows all the programs are at current versions.
My other test is to run GPSMON to verify that GPSD and the GPS are working. When I first used the image, GPSMON worked. But after I expanded the image for my 32GB card, GPSMON no longer works. GPSD starts but does not allow GPSMON to work.
I have no clue why after expanding the image GPSD/GPSMON no longer works - I ran N7NIX's gp_install.sh script but that did not fix the problems.
I did not try any other programs.
Suggestions are welcome - I do have my own image that works and is fully expanded.

zip definitely works, i did that yesterday.

It seems this taring it to an .xz file was not compatible with Etcher.

You can uncompress the .xz file (tar -xJf Buster-Draws-2019-09-01.xz) and flash the resulting .img file to the SD (I tested it and it works) or Ill send another message when the .gz file is uploaded to dropbox and you will be able to download that file and it will work with Etcher (again I have tested).

Sorry for the error.

I downloaded this image this morning - Balena Etcher gives an error that there is no file system but allows it to be copied / loaded onto an SD card. I attempted to run it on an RPi 3B+ with DRAWS mounted on it but it does not boot - so Etcher is likely correct that it has no readable FS.

Perhaps this helps... from the rasp-config documentation 

Advanced Options

Expand Filesystem

If you have installed Raspbian using NOOBS, the filesystem will have been expanded automatically. There may be a rare occasion where this is not the case, e.g. if you have copied a smaller SD card onto a larger one. In this case, you should use this option to expand your installation to fill the whole SD card, giving you more space to use for files. You will need to reboot the Raspberry Pi to make this available. Note that there is no confirmation: selecting the option begins the partition expansion immediately.

I think the early adopters case should be for the pi3 only, this is what I paid for. 

Now, if they ever redevelop them and then have them made, there will be unused holes that will look bad.

I was beginning to think I would never see the case I ordered. Guess there is still hope.

Likewise. After doing some work on RPi4 to confirm there were no issues on Buster (on either the RPi3 or RPi4), I've moved my DRAWS / udrc hat to an unused RPi3 sitting in a little box above a shelf mounted older Icom radio; it's now on the air full time as a local APRS digipeater and IGate and will soon have a second radio providing service to a secondary "low power" APRS device frequency in our area.

Yes, I'd love a case. One user here noted 3D printing one; that might be an option I'll pursue. In the meantime, the device is being used.

Buster Image with DRAWS software

For those that want to just download an image for their DRAWS setup - here is an image that should work on Pi3 or Pi4 based on Buster.  It uses the DRAWS drivers that NW Digital submitted to the Raspbian source tree and now come with Raspbian.  So you should be able to update the software with the normal sudo apt update and sudo apt dist-upgrade.

Just download the file - it is a .xz and Etcher will flash it directly to the sd.  The account is the normal pi with the normal password of raspberry.  It should boot into the desktop.

You will want to expand the SD file system - just do a sudo rasp-config then go to option 8 - Advanced, add chose expand file system.

When you have booted the image with the DRAWS hat installed enter the command aplay -l. It should list the udrc soundcard.  If you have a newer board or if you are curious you can try commenting our the dtoverlay= line in the /boot/config.txt file and see if the soundcard still shows up.  If it does, you can leave the line commented out.

In any event - here you go - enjoy.  https://www.dropbox.com/s/wpap6fhkctqalxt/Buster-Draws-2019-09-01.xz?dl=0

Well, I've got mine just sitting bare at the moment, haven't done a lot other than tested receive with the board due to lack of time.

My plan is to throw it into the top-box on a bicycle, it'll be interesting to see how the DIN-6 connectors fare with the vibration. It'll be doing APRS/AX.25 packet and voice relay via WiFi (either using something WebRTC-based or using mumble, we'll see).

I don't dare even try though without that little computer in a case to stop it getting dinged up, and it'll need to be substantial on the RF front as it'll have a HF antenna (with 100W pX TX power) and a VHF/UHF antenna (with 50W/20W pX TX power) within a 1m radius of the computer.

I understand the hold up is that the case is being re-designed to accommodate the Pi4; hopefully without reducing its utility to Pi2/3 users.

The questions in my mind are how many of those waiting for a case are actually wanting to use it with a Pi4, and how many cases of the older design were "in stock" at the time the decision to re-design the case was made?

I can only conclude that perhaps not many were in stock and the wheels of manufacturing hadn't yet started turning on a new batch.

Hopefully the re-design is a short process, otherwise maybe it'd be worth maybe just doing a production run of Pi2/3 cases in the mean time so that those of us with older stations can protect our investments from the elements.

I also have been waiting for mine for the same reason. My hat is just sitting not in use until I get the case. Sure do hope we get an update soon. And it would be nice to know they know I paid for one along time ago.

I really hope I can get the discounted early adopters case I ordered last April. Or it would be nice to know if we will ever get the case. I wanted for its emi shielding and power port. Cases for these boards are limited.

Lets confirm that measure_deviate.sh is working properly. Could you
please cut & paste the console output of all the commands below.

piver.sh
udrcver.sh

# Using o-scope check both left & right channels.

cd
cd n7nix/deviation
./measure_deviate.sh -c left
./measure_deviate.sh -c right

# Verify gpio 7 is set to correct mode
gpio readall | grep -i "gpio. 7"

Thanks,

Sounds great, Basil!

We currently have 9600 APRS available with satellite FalconSat-3, so I'll give that a try when there's a favorable pass.  With the volume of cubesats being deployed these days, hopefully there will be more with 2-way 9600 capability soon.

With an FT-857d connected to the DRAWS & up/down freqs being

Of course the UISS program on Windows is more capable, but sometimes
