Where can I download the CrowPi2 latest image?
The official CrowPi2 system image is last updated to Debian 12 (bookworm) on 2024-02-03 and it is available for download here.
Note:
- It's normal for your system to restart once, when booted for the first time, in order to expand the filesystem automatically.
- A microSD card with 64GB or greater capacity is recommended for running the latest bookworm version.

At the bottom of the page on how to install the OS Image to an SD card there is a statement that says...."insert the card into the SD card slot on Raspberry Pi. Plug the12V2A power adaptor then press and hold the button for a while until ELECROW logo show on the screen."
Which button?
TIA
It is referring to the Power Switch (6) as shown below:
Do I use the 32 bit or 64 bit image?
It all depends which Raspberry Pi model (i.e. 3B, 3B+ or 4B) you are using. If your Raspberry Pi has 4GB or more memory, it would be a no brainer to use the 64-bit version.
The main difference between 32-bit and 64-bit systems is the amount of memory they can address. A 32-bit system can address up to 4GB of memory, while a 64-bit system can address much more, up to 16 exabytes (which is 16 billion gigabytes).
In summary, a 64-bit operating system typically runs faster and more efficiently on 64-bit hardware compared to a 32-bit operating system, especially when memory usage and application compatibility are considered.
I flashed the 64 bit image but it will not take the over 500 updates. It says there are over 2 GB of updates unless I deselect the bottom few.
The 32 bit version eventually took them all.
Neither one is the same as the OS that came with my CrowPi2, especially the getting started.
This is very frustrating since I have hardly started to use it.
I managed to install about half of the updates but the CroqPi2 became more unstable. Now there are 250 left and I get "Fail to Process Request" when trying to install just one (e.g. "Mathematica and the Wolfgram Language" or Enu version of the.... or Mesa VDPAU or any above them in the list. When I reboot and select the Raspberry (menu) I get a black line across the top and can unlock it by selecting the Calculator. Very unstable behaviour.
Raspberry Pi 4b, 64 bit OS, CrowPi2.
Has anyone successfully used this download and updated it?
Can I buy the OS on a micro SD card?
I've tested downloading and writing a new copy of the same OS image to a 32GB SD card. It boots and operates correctly on my CrowPi2. But there are some issues.
These are my observations:
An error message Failed to load dtoverlay 'pac9557_i2c' appears at the upper right-hand corner after showing the CrowPi2 Software Desktop, caused by a line statement dtoverlay=pac9557_i2c,addr=0x18 in the config.txt file.
Corrective action: This can be easily corrected by comment out (#) or delete that offending statement in the /boot/firmware/config.txt file.
The root partition did not automatically expand to occupy the full SD card capacity. Thus, the possible free storage shows 1.6GB out of 25GB total.
Corrective action: Run raspi-config to expand the filesystem. Afterward, the possible free storage should be improved to 5.6GB out of 29GB total.
The Raspberry Pi OS is quite outdated as expected. When proceed to update in the Terminal,
Corrective action: Use a SD card with a storage capacity of 64GB or greater. Also, using a card with the A1 or A2 rating is highly recommended for best performance.
I think the bottom line for your trouble is there are not enough free storage space for using a 32GB SD card, I presume that's what you're using. So, start over with a 64GB or greater capacity SD card.
Hope these can be of help to you !
Thanks, I am using the download without modification on a 32 GB card and it works OK.
I will pick up a 64 GB in a few days and try it, I can't buy them locally.
@Rovman Just a head-up, you will most likely need to manually expand the filesystem after writing a new SD card with this downloaded image. The root partition will still be only 25GB even if you have a 64GB or greater capacity SD card. If you're not familiar with the procedures, follow the instructions on 'How to expand the Raspberry Pi filesystem'.
Alternatively, if you’re satisfied with your current software setup, you can use the SD Card Copier utility to clone your current SD card to a new one. The process will automatically create the root partition size based on the available storage space of the target SD card. See 'How to backup the system SD card' for instructions.
