5) define the boot order
now I can set the boot order with the command:

sudo raspi-config
chosing Advanced options > Boot Order
Schermata-2022-04-23-alle-11-28-22.png

6) set the root PARTUID of SSD
On SSD I can now set the new PARTUUID for root volume:
sudo nano /boot/cmdline.txt
and replace the SD PARTUUID to the SSD PARTUUID:
root=PARTUUID=9efc3dd8-01 root=PARTUUID=0860e500-02

7) define the mount point on SSD
sudo nano /etc/fstab
fstab.png

Now, rebooting I have this:
astroberry@astroberry:~ $ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    0 465.8G  0 disk 
├─sda1        8:1    0   256M  0 part /boot
├─sda2        8:2    0 146.5G  0 part /
└─sda3        8:3    0   319G  0 part /media/astroberry/astrofoto
mmcblk0     179:0    0 116.2G  0 disk 
├─mmcblk0p1 179:1    0   256M  0 part /media/astroberry/boot
└─mmcblk0p2 179:2    0 115.9G  0 part /media/astroberry/rootfs
where "sda" is the SSD and "mmcblk0" is the SD.
If I remove the SSD it boots with SD and I have:
astroberry@astroberry:~ $ lsblk 
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk0     179:0    0 116.2G  0 disk 
├─mmcblk0p1 179:1    0   256M  0 part /boot
└─mmcblk0p2 179:2    0 115.9G  0 part /


The speed is improved:

I had a 500 GB SSD used as cache on my NAS but the estimated lifespan was going too down so I’ve replaced it.
Now I’m using the SSD in an USB enclosure attached to Raspberry Pi 4 to boot Astroberry, but due to low estimated lifespan (1%), (and because I don’t know where to store the Astroberry microSD without loosing it :) ) I’ve set the microSD as fallback.
Here how I’ve made it.

I’ve just seen the indi_joystick driver. Once added as as AUX device, connecting an USB Joystick I can control the focuser. I’ve also installed

sudo apt-get install joystick
and added a Bluetooth PS4 controller. I hoped in an analog control (slow focus in to fast focus in and the same for focus out) but I see only "Focus in", "Focus out" and "Abort focus" buttons.

Hi there, I’m building and Astroberry focuser . In KStars control panel I can see a Joystick control but I can’t find informations about how to connect the hardware and how to setup. Is it a “GPIO” or USB Joystick?

I’m having the same issue with a Sony a6400. It crashes sometimes sending the images to plate solver too. I’ll try with a NEX6 soon.
