Thank you, Jason; Lincoln; Mark - this is a great endeavor !

I started watching a couple of weeks ago and missed out on the Developer Kickstarter - so I contributed at the next level. I'm a hack SBC developer - but I'd like to contribute. My Vantec NBA-200U was delivered yesterday and my pi is playing XM radio over it now over the 'front' channel. If it will be possible to get an 'early adopter' product, I'd like to help with some home automation ideas I have.

I followed the DEVELOPING.md instructions an did a deploy. The first time through: I followed the script's instructions to " set RPI_IP_ADDRESS. When I run_debug_webserver --mock-ctrl I get 3 errors:
line 41: venv/bin/activate no such file ( I have venv installed and a django instance installed)
line 43: flask: command not found ( I've not installed flask )
line 44: deactivate (command not found)

I've attached (renamed to .txt)
asound.txt
my asound.conf for the mock board. did I follow instructions correctly ?

Please advise on how I should correctly setup for development...

Looks like there is a bug in the deploy script that doesn't handle the case where venv is installed but hasn't been created. Let me see if i can give you a quick fix.

Can you attach the output of the deploy script? It calls the update_config.bash script that installs most of the necessary packages. You can also try running update_config.bash on its own and checking the output.

You may also want to ad the line set -e to the top of the update_config.bash script so that it stops at the first error.

pi@raspberrypi:~/amplipi/AmpliPi/scripts $ ./deploy

Please set RPI_IP_ADDRESS, for example:
export RPI_IP_ADDRESS=192.168.0.140
for ssh key access
export RPI_IP_ADDRESS=pi@192.168.0.140

@vszander I've updated the comment above. If you checkout ampli in /home/pi you wont need the mv command.

my Django is served by apache... so I'm hoping they can both co-exist. since nginx is serving for port 5000. I didn't see you post about not installing 'unit' so it got installed ( I can always roll-back by pi's SD card ).

But my update_config.bash is throwing errors ( python 3.4 is installed - maybe I need to get 3.7 ), maybe it wasn't designed to build from the pi itself ?
output:
E: Unable to locate package /home/pi/AmpliPi/config/../debs
E: Couldn't find any package by regex '/home/pi/AmpliPi/config/../debs'
E: Unable to locate package /home/pi/AmpliPi/config/../debs
E: Couldn't find any package by regex '/home/pi/AmpliPi/config/../debs'
Updating AmpliPi's Nginx Unit webserver configuration
Failed to restart unit.service: Unit unit.service failed to load: No such file or directory.

If it would help, I could collaborate w/ you on webex ? my gmail is: daytona.zander1@gmail.com

The deploy script should have copied everything into /home/pi/. Running stuff from the repo folder /home/pi/AmpliPi will not work since the base folder is now /home/pi/AmpliPi instead of /home/pi. Try running the debug webserver from there:

cd ~
./scripts/run_debug_webserver --mock-ctrl # --mock-ctrl pretends there is a AmpliPi controller there

We are working on packaging AmpliPi into a release, so all of the relative path issues will be solved relatively soon. Sorry that you had so many issues with this.

Thanks, Lincoln. I understand, now, how you are developing - and it makes sense. I'm working to create a similar setup. My delay has been: I had to upgrade my version of python and openssl... hopefully I'll have a breakthrough soon. I'm trying not to burn up your time ( which is better spent getting ready for production) on my silly questions ! Kind regards, Van

Hi Lincoln, Hope you are well ! It looks like there are some delays in developer units ? I'd like to contribute - but I had so much trouble getting an SD card image to work .. Is there a way I could get a linux 'dd' image file for a a basic/ latest build ? I purchased the recommended sound card and would like to see if I can contribute. Thank you for your efforts ! Van

What pi are you using? In our office we have a pi3 and a pi4, so we can pretty easily make a working image for either a pi3 or pi4.

I also have both. But it seems like the AmpliPi will ship with Raspberry Pi3... so lets go with that. I think you also asked what my IP was... my public is: 67.191.140.146 inside, my NAT'd addresses. 192.168.35.138 Raspi 3 192.168.35.144 Raspi 4 If you plan to ship with Raspi4 , I'd also like to work on a Raspi4. Thanks ! Van

@micronova-jb is working on creating a defacto image for our first 5 AmpliPis. We should be able to get you something that works in the next couple of days.

Hey Van! Sorry for the delay - I was trying to figure out a way to actually get this to you today. Does this Google Drive link work for you? You may have to request access: https://drive.google.com/file/d/1HLGoI8innn-Ur6-T1AUBfP6ZJbJZ4Etn/view?usp=sharing

Better yet, this should be easier: https://www.dropbox.com/s/hpqvukgqshzna7d/aptest_1.4.img.7z?dl=0
