Re: heatsink -- was [Re: Raspberry Pi 4 is announced]

[Alan Corey]

Thank you, I hadn't looked at that.  So there's Debian for it, not
just Ubuntu?  I have 3 Raspberry Pi 3s but for a higher performance
machine I have a Rock64, which isn't entirely satisfactory.  I'll poke
around Odroid's forums a little and probably order one.  It looks more
like a car stereo and in fact it even has audio DACs.  Support for the
Rock64 is mostly in Chinese, this is Korean, we'll see.

Hostname v buster

[Gene Heskett]

Greetings;

I just updated a pi3 to buster, presumeably rc2.

But I used RealtimePi to install a 4.19.50-rt-v7 kernel into the image.

That conversion insists the hostname is realtimepi.  In stretch I could 
fix it to the name I'm used to by setting hostname, then sudo chattr +i 
hostname, and it would stick over a reboot, but not in buster, despite 
the immutable bit being set, its been reset to realtimepi after a 
reboot, this despite an lsattr still showing the i bit is still set!

So that I need help with, and since my network is static, avahi is 
screwing with my routes, and that disables my dns lookups outside of my 
local network because it issues a ping to an outside address from 
the .local address in the 169/24 block.

So I've got to nuke whatever is sourceing the 169 junk to the ifup 
command.

Help please & many thanks.
 
Cheers, Gene Heskett

Re: heatsink -- was [Re: Raspberry Pi 4 is announced]

[Alan Corey]

Unless you're going to overclock it (which I'm not sure is possible,
probably) you don't need a heat sink.  It will throttle (reduce speed)
if it gets hot.  A heat sink keeps it from overheating so soon so it
can run at full speed longer.  If you run cpuminer (to mine Litecoin
or Bitcoin) it will overheat a Pi very quickly and slow down, even
without overclocking, because it's so CPU-intensive.  You can run less
threads to run cooler.

What I'd like to see is a massive heat sink that dwarfs the circuit
board and becomes dominant, sort of like with Pentiums, could even
have a fan.  You'd mount the heat sink then bolt the Pi to it,
probably with heat sink compound or a heat-conductive washer.  The
connectors and wires would go wherever they ended up.  There could be
such setups as aftermarket addons.

I don't like that they continue to push the power connector to its
limits instead of going to something else like a coaxial plug like the
Rock64 uses.  I'm not sure it it's still a microusb or not.  But you
can always power through the GPIO connector.

And this uses _micro_ HDMI connectors, as opposed to the Zero which
uses _mini_ or the earlier Pis which have just a regular HDMI.  So if
you have a slew of Pis and Zeros you need 2 adapters for video.

GPIO pinout at 
https://www.element14.com/community/docs/DOC-92640/l/raspberry-pi-4-model-b-gpio-pinout-with-poe-header?ICID=rpimain-smartpanel-pi4doc
I'm not sure how different it is.  The Pi GPIO has gotten to be a
defacto standard that other manufacturers also use.  I see there are
still multiple 5 volt and ground pins so they can be paralleled for
more current capability.

I welcome the 4 GB of RAM the most, I use 2 swap files and get tired
of waiting for swapping and unswapping.  Hopefully the ethernet is no
longer tied to the USB.

There is a new case and power supply, at least partly for the 2
micro-HDMIs.  A Rock64 fits into a Pi case but the power connector is
different so it needs some filing.  The cases are sort of a nuisance
because the wires dominate everything and are much heavier.

heatsink -- was [Re: Raspberry Pi 4 is announced]

[Rick Thomas]

So when I buy one of these in a couple of months, do I need to buy the heatsink 
too?  Will the heatsink fit into the standard case?  If not, is there a case 
that will fit?

And, finally, is there a version of Debian that will run on one of these?  Or 
should I just plan on running Raspbian?

Thanks!
Rick

No big surprise there.  Something about 1500 more on 7/4.  I got on
the list to get emailed when they get them.  Oh well, time to get
adapters ordered, and a different power supply.  Looks like they built
it to bolt a heat sink onto, there's free space around the CPU.

FWIW, I've just found that raspbian now has a buster download (in 
progress but failed and restarted many many times, and that CustomPiOS 
has been updated to buster's kernel, which is or should, generate a 
realtime image based on buster with a 4.19-50-rt-v7 kernel, which should 
be new enough to accelerate the video, but the wording is vague like it 
needs a rpi-4 to work right.  So we'll see if it will build.  Then we 
try it on a pi3b. More later, maybe.
