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!



This may help...there are instructions in here about expanding the drive space...

Well then you are stuck with the old firmware, which does not work well at all with INdI...... Simples...
I was only trying to help...

Some problems with the current values, but this must be due to my old firmware version which I cannot update because Pegasus does not provide its firmware on its site :(


They do provide firmwear updates, you have to connect the UPB to a windows machine and when you open the software it will check and find the firmwear update and then install, it’s an automatic procedure....

I followed the article
Disk /dev/sda is my disk
and the article said to
root=/dev/sda2 rootfstype=ext4 rootwait
in cmd.txt - is this correct to type it "sda2" even though my disk is "sda"?

Then when I reboot and "df -h" it says I have 28 gig freespace which the article says I need to free up space....
Do I need to check which disk I've booted off or something?

Thanks for this help[ I really appreciate it.

Hello,
The link I sent you above with the instructions I have only used with raspbian based SM Image and the older SM image based on Ubuntu 18.04, I have not tried with newer ones so can’t comment on those...
As for the SDA disk you need to find out the number of your external SSD drive and I put that there, if there are no other drives attached it will be sda1....it WONT be just sda there will be a number after it..

Yesterday, I also ordered Flirc aluminium heatsink case (without cooler) and SSD.
And I already have a Pi3 so I was planning on using the same power supply (different cable) which is a PowerBank that supplies 5V/3A.
www.avxperten.dk/powerbank/powerbank-300...-deltaco-pb-1069.asp

I have a CEM25P mount so I hope to get the time from the GPS module on the mount, so maybe i dont need the RTC module? Or will that still be necessary?

I also heard about the interference issues so I bought a USB WIFI Dongle with 5 dbi antenna for the Pi and a non-powered USB hub (can supply a maximum of 900 mAh which is enough for camera and guider)
So I was planning to still use the USB ports directly in the Pi (for the USB3 Hub and the SSD harddrive for example). But maybe that is a bad idea?


It’s not about what power the hub can supply, it’s about what power the RPI Can supply to the hub, and it’s certainly not 900ma to each port, you need a powered hub or you may as well Attach everything to the RPI direct as you are not gaining anything at all...

I just ordered a Pi 4 and I am planning to install StellarMate OS on it, but I won't bother if there are any known issues :-)

I would prefer to use StellarMate OS but if that is not an option I will go for Ubuntu with KStars/Ekos instead (or maybe Astroberry server).


Stellarmate works perfectly fine with the rpi4, and has done for some time now... :)

In terminal

If you run these commands, you will end up with the nightly INdI version, and not the stable version, and the nightly could be buggy....so think before you update the INdI core...

It was in earlier Pi's, buhas been widely reported that you can't do it with a Pi 4? My Pi 4 lost it's microsd card reader (seemingly a not uncommon occurrence . If I could boot from an ssd I could salvage it.....

Yes it can be done with an rpi4 but you still need an SD card in the rpi with the boot partition, then everything else runs from the SSD
