Please use this thread for discussing 4.3.2 - I hope this one will go to production release, but I really value those brave souls that beta test it and help me work the kinks out, so please download, burn, enjoy - and let me know how you get on...
Changelog:
Code: Select all
10-Apr-2025 **Version 4.3.2 BETA RESPIN #3** - Available for Download.
You will find that you cannot upgrade 4.3.x to 4.3.2, this is
because too much of the core system needed to be
modified to produce 4.3.2, yes that really does mean
that you need to burn yet another card to use this one.
I hope this will be the last beta, and *should* go into
mainline / production use once you all have a chance
to test it.
4.3.2 has a seperate set of binaries from all previous versions,
it does still share the scripts etc, but all of the DV
software is new/up to date with current. This may cause
some of you some issues, but please do your testing,
this is why we release as beta after all.
IPv6 has been enabled in this system matching the lastest 4.2.2
build.
Wi-Fi bugs as seen specifically on Pi02W (and only this SBC)
have been resolved *I think*. Thank you to Chip (W0CHP)
from WPSD for the tips.
Kernel changes, I have removed the v7/v7l kernels, they are just
not required, they have some GPU performance advantage
on Pi2 boards, Pi-Star does not need/use the GPU.
Everything from the Pi3 and onwards uses the 64Bit
kernel by default, including the Pi400, Pi500 and the
Pi02W. Please do not confuse this informaton, Pi-Star
still supports ALL Raspberry Pi Foundation hardware,
and should boot perfectly well on all platforms.
Temperature control / Reduction - there was an issue with Pi4
and Pi5 hardware that was causing the CPU to run at
max clock ALL the time, we just don't need that, and it
was causing Pi4 and Pi5 SBCs to run REALLY hot. Now
resolved.
GPU Underclock - This is required on the Pi02W for Wi-Fi
stability, yes this sounds insane, it relates to how
the Wi-Fi is connected to the the SoC, I have also
applied the same GPU underclock on other models, I do
not expect any issues arising from that, but this is
a deliberate move to slightly reduce power use and SoC
temps.
CPU Underclock - Again this might sound a little crazy, but
the idea here is to slightly under clock the CPU to
help keep the operating temps down. Keep in mind that
we already set the throttling temp to 75C (rather than
the factory 85C) in order to prolong the life of any
Raspberry Pi Foundataion boards, this step is more
about helping knock the edge of running temps rather
prolonging life. Pi 4 / Pi 5 retain full clock speed
since most people are running coolers on them already.
