The new Raspberry Pi 4

Post by locutusweb »

The new Raspberry Pi 4 B is here: ... 4-model-b/ Yihaaa!

Just one simple question: will my favorite Pi OS run it? (that's ofcourse DietPie :D )

I would also like to know if DietPi will support the new Raspberry Pi 4. As I understand the CPU is ARMv8 instead of v7. would that pose a problem?

According to Debian it should work.

2.1.2. Three different ARM ports
The ARM architecture has evolved over time and modern ARM processors provide features which are not available in older models. Debian therefore provides three ARM ports to give the best support for a very wide range of different machines:

Debian/armel targets older 32-bit ARM processors without support for a hardware floating point unit (FPU),

Debian/armhf works only on newer 32-bit ARM processors which implement at least the ARMv7 architecture with version 3 of the ARM vector floating point specification (VFPv3). It makes use of the extended features and performance enhancements available on these models.

Debian/arm64 works on 64-bit ARM processors which implement at least the ARMv8 architecture. ... .en#idm275

Also it looks like Dietpi added support for ARMv8 back in 2017

DietPi-Software | Gitea: Install updated to 1.3.1 (for new installations only). Added support for ARMv8. Now installed to
/mnt/dietpi_userdata/gitea, runs as dietpi user: ... 9863#p9863

@locutusweb @lasy @Edward
To clean things a bid up:
  • Jep RPi4 has an ARMv8 capable CPU, but this was already the case for RPi3 and even the later RPi2 models:
  • To assure compatibility of their software across all RPi models, Raspbian calls all RPi models as armhf, the RPi1+Zero as ARMv6 (with special hard-float capability) and all other models as ARMv7.
  • So theoretically Debian ARMv8 works already for quite a long time on RPi, but we stick with Raspbian as DietPi basis, as it assures full compatibility, a wide user/support space and the benefit of ARMv8 is marginal, when loosing some special compilation settings + performance-related packages from Raspbian, possibly even negative.
  • RPi4 requires a new kernel tree (v7.1+) and bootloader files. So our current image does not work. Also, due to not further mentioned compatibility reasons, Raspbian for RPi4 is only offered as Buster version. Luckly we started early to make DietPi Buster compatible ;).
  • Fourdee create a first DietPi image based on the new Raspbian: ... -506389899
  • Note that this is still experimental. On the one hand, Raspbian Buster itself still lacks some features and requires some fine tuning, on the other hand DietPi "dev" code is present on this image, which is currently in Beta, so still might need some fine tuning as well ;).

I'll be playing with the Ri4, when it arrives in the next few days, as a replacement to my Xu4 which runs bittorrent/Plex.
My current plan is to install the Buster version of Raspbian then use the DietPi Prep_System script to convert. Would this be the best way yo go for now?

Jep, the new Raspbian Buster is anyway required for RPi4 support. We also created a first testing image that way: ... -506389899
Note that you must use the "dev" branch version of DietPi-PREP and select it there as well, until v6.25 is released, expected soon:

Received my Pi 4, Raspbian-buster is out, Debian 10 Buster is officially released.

Any updates on the DietPi version that is ready to support this - full release?

I have the Raspberry Pi 4 Model B, 4GB version. If I install the experimental image, will I be kept on the experimental branch? What is the recommended way to install for me?

I own a Pi 4 and ysterday I flashed the experimental image based on Buster (DietPi version 6.25.3) and I have no issues! 8)

I know that in Buster NFtables replaces iptables, does the Fail2Ban dietpi-software work with this new firewall? :?
