Rock 4C+ Best debian ISO

Hi ,
I’m goin to buy da Radxa 4C+ board . I know raspberry pi 4 but i’m new with this board
I wish to use a Debian 13 without graphics ( only cli / term ) bacause board will act only as server
I also see that official image is only the Debian 11 with kde
What image do you suggest to use that have a good ( best support ) and continous update ?
Thanks

The official image is already Debian 12 now. But for your use case a 3rd party Debian 13 should be fine.

Maybe also see Pure Debian 13b on the board? - #2 by radrocks

Also note it is not Intel/AMD PC’s here, ‘ISO‘ means CD-ROM iso9660 read-only filesystem, and does not contain a pre-installed Linux OS, rather is starts an installer program (on UEFI x86-64) so that guides you with installing Linux on destination storage while applying various settings, preferences and credentials.

Older SBC’s do not contain standard UEFI BIOS/firmware/bootloader, so need dedicated bootloader per type of board (mostly U-Boot) that is why endless amount of images are available, they are essentially all the same, or can be, except for the hidden U-Boot at the start of the image. The 4C+ has no storage for firmware, so you need SD-card (or extra eMMC) for bootloader. If you use modern, good enough U-Boot, it will understand EFI bootable images (or ISO) so if you search more, you can find Debian ARM64 ‘ISO’ that you write to an USB-stick and then with U-Boot/UEFI on SD-card, you can install Linux the traditional way like on PC’s, but you need yet another additional storage device (a SATA SSD connected via SATA-USB3 adaptor for example).

So ‘Best debian ISO‘ is really depending on your OS/Linux installing skills and or what you want/need. I use Raspberry’s with Debian, but it needs special/foreign UEFI in addition as well, so not as easy as computers that come with UEFI out-of-the-box. But once done, it is then the same als all your Debian computers, so quick security updates etc.
