Raspberry PI 5 & DietPi

[morphious]

Its official - Raspberry PI 5 was announced for mid-end of month of October shipping.

Of course, my question will be, how long before DietPi supports the new board?

*my personal interest is an upgrade from Pi 4 to Pi 5 with PCIe m.2 SSD to speed up our WordPress hosted website.

I already ordered RPi5 8GB to upgrade my 24/7 running RPi4 4GB with DietPi

I hope that idle power consumption will be better than RPi4.

“At idle, without any added cooling, it sits at around 50.5 degrees Celsius and consumes around 2.7 Watts.”

But Jeff mentioned in his video that RPi 5 has lower idle power consumption that RPi 4:

we are checking for developer samples. Let’s see how this is going.

Explaining Computers on YT did a power measurement…running wide open…it was pulling 6 watts…and was about 50-70% faster across the board on almost all benchmarking metrics

Best review yet!

Looks like good start but many issues to resolve before Dietpi is stable for Pi 5… Please keep us informed!

RPI5 update: I’ve set up my Pi 5 using the github migration script and run rpi-update for the latest bootloader (EEPROM).

Linux PI.sl.com 6.6.16-v8-16k+ #1732 SMP PREEMPT Tue Feb 13 13:13:56 GMT 2024 aarch64 GNU/Linux

I’ve installed the Geekworm X1001 MVMe HAT with a Samsung 970 EVO Plus m.2 SSD.

I used rpi-clone to clone from the SD used to migrate to SSD drive. Changed the boot order from BOOT_ORDER=0xf461 to BOOT_ORDER=0xf416.

It is now booting to the M.2. Here are the results of the ditetpi-config benchmarks:

An amazing speed increase!

I will use this headless to host WordPress websites. Here are the changes I found to be stable and added to /boot/firmware/config.txt

V9.1.1 updated perfectly on the Pi5 with no issues.

As the unit is sitting at ~45c I upped the default 1500 to arm_freq_min=2800 in the Config.txt. It caused the temp to go up to 47c and Total Watts used at idle increased from 2.032 to 2.1841. Well worth it for the intial latency bump in speed.

I use the same version. Runs smoothly. But does anyone know how to activate OpenCL for Video Core VII on Pi5?
