Yes - you can boot directly from ‘any’ USB storage device. My Astroberry implementation now resides on a Sandisk Extreme SSD which is super fast. I have also tried out a 1TB 2.5” hard drive in an IcyBox USB3 carrier. It works pretty well although RPi agnostics tests gives an overall FAIL due to random read /write speed being a little below the test threshold score.

Progress !
So I now have Astroberry 2.0.1 running on my RPi4 directly from a Sandisk Extreme SSD. I followed a couple of videos on Youtube ( youtu.be/zVhYvvrGhMU and youtu.be/AskGItLhESk ). Once I had Raspbian Buster running from the SSD with no microSD card, then using Balena Etcher, I burned the Astroberry 2.0.1 image to my SSD. I copied into the boot partition the 14 .elf and .dat files which are on the GitHub repository (as described in the second YouTube video, and as I had already found successful with the plain Raspbian) . So Astroberry now boots at lightening speed from the SSD. Only one small problem yet to solve - I need to expand the file system to occupy the whole of the SSD. At present I have access only to around 8GB of the much larger SSD. I tried using raspi-config Menu item 7 Advanced Options Menu item A1 Expand Filesystem but get the message "sda2 is not an SD card. Don't know how to expand".
I guess I need to seek some help from the experts on the RPi forum!

One final 'cure' remains for me to test, to attempt to drain down the internal power source which maintains the date and time and camera optional settings. I have removed the main battery, but I haven't a clue how long I will need to leave it to drain down, or if this may be any help at all! By the way, the camera seems to function quite normally when used in standard camera modes (P, AV, T, Auto etc) with shortish exposure times up to half a minute.

I am using the Astroberry Server 2.0 on my Raspberry Pi 4 4GB, and have carried out a sudo apt update && sudo apt upgrade, but otherwise not looked deeper at which Indi driver I am presently using.


Not sure why this problem suddenly occurred after six months and more than a thousand image captures (mostly Darks and test exposures!), however it seems to have been cured by going deep into the ‘custom’ settings menu on the camera and disabling all of the features that are not needed when imaging, especially long exposure noise reduction.

It seems that the RPi foundation has issued a beta version of the USB bootloader (which does not require a microSD card in addition). I presume I could install Astroberry onto my USB SSD after setting the SSD up as the (only) boot device. But is there a way of using the Astroberry 2.0.1 image file directly?

Have you tried installing it by hand?

Not yet - my software experience is limited - I would need my ‘hand’ holding by someone more expert.....

Radek,
I have been following some work on building a live stacking function to run on a Raspberry Pi 4 (see als-app.org/index.html ).
In the latest communication from the authors, they have developed a software package to run on the RPi4 under Raspbian. Although in an early stage version, could this be added to Astroberry? (see post #8 in this thread www.cloudynights.com/topic/683836-als-astro-live-stacker-v06/ )

I sympathize with your frustration - the learning curve for linux/kstars/ekos/indi is just as steep as the learning curve for much of the things we attempt to do in AP, but from what I have read, taking the 'Windows system' approach would be equally fraught - I read on other forums the difficulties that others have in piecing together a Windows-based NUC with many hardware and software issues.
We Astroberry users all start from the basis of one hardware platform, these days mounted on the Raspbian linux distribution which is in massively used and professionally supported, with the Astroberry collection of open source softwares as the icing on the cake.
You are right that there are missing features of KStars/Ekos/indi such as you mention 'no USB/DSUSB long exposure control, no dual camera sync for dithering/guiding'. I don't know what these are and if your setup needs them then there is no instant fix. You would have to submit some requests for new features to be added to the Indi forum and hopefully some of the excellent voluntary development team would see the benefit of adding to the Indi arsenal.
You mention technical issues of connecting 'the moment I try to connect to astroberry from outside network it collapses'. It's just possible that this may be due to some interference that other users have been reporting between the USB3.0 functions and the 2.4GHz WiFi channels of the RPi. I personally set up the Astroberry hotspot to prioritize the 5GHz bands.
Overall I am amazed at how well Astroberry on the RPi4 functions, how reliable it is, and I am enjoying advancing slowly on my AP journey with its help (and the posts on this forum and elsewhere)!
