can you check if this is set to ondemand or performance?
# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
(in my case with a RPi CM4 the performance governor increases temp from 40 to 48 degrees)
Try the new build, I store all the kmod locally.
The fan on the rpi5 will activate pass 50°C, OpenWrt uses less resources than other distros, for this reason in a well ventilated case the fan will not spin unless the rpi5 is stressed.
I have the rpi 5 in a case and fan works.

Seems to be set to "ondemand"
Thank you!
Everything works with this build.
I like all the additional utilities I had no idea openwrt had~ I'm having alot of fun with them 
Unfortunately the uhh... A76 chip seems to at least for me like to scale beyond, and heat the SDcard... like... Scary kind of heat. I Might need to invest into a different storage method~
I just slapped a random case fan I had laying around and the thermals seem to be okay around the cpu now, but the sdcard is still a bit more than warm
My ambient temps is atm 18c so an external fan really helped improve the temp (previously would go around 50c-60c)
as long as you take regular backups (like after every working config change) and don't store anything else on the μSD (like docker/lxc containers doing heavy I/O) you can easily restore the working state on a new card
Thanks @mj82 !
As a naïve noob I bought a Pi5 and USB ethernet dongle hoping to use it as a router. I flashed the Nov 29 image from git, and it all worked straight out of the box.
I didn't expect it to go so smoothly. Now with Cake, I'm now realising how but my previous router was at introducing lag to my connection.

Total newbie here, bought a Pi5 at Microcenter, mainly because it was only $5 more than a 4.
Apologies if I am in the wrong place, redirect me if necessary, but I was attempting to openWRT a pair of Merakis using this guide https://roamingviews.com/tech/how-to-flash-openwrt-on-cisco-meraki/ and I do not have a ttySO, I only have a serial0 of ttyAMA10. Do I need to buy an older Pi?
No, the RPi5 can do everything the RPi4 can. The problem is 'just', that the RPi5 isn't quite supported by OpenWrt yet - meaning you either have to wait for the support to be merged or build from source, using the existing pull request yourself.
If you only want to use the RPi5 as serial terminal, running an already supported distribution, you should be able to so - how the serial interface is named is immaterial to that.
So it has more to do with me not knowing what I am doing besides following a guide than anything else? I don't know the ins and outs of openwrt, or even the pi itself.
I wouldn't have the slightest idea of where to begin with building or pulling, so if spending another $50 or whatever on an older model accomplishes the task, I have no issue doing that.
You can achieve the task described in the guide you linked using only USB TTL serial adapters. Much less expensive and simpler than spinning up a whole computer just to access another device's terminal.
Since you appear to have access to a Microcenter, here are your USB TTL options that you can pick up today (if they're in stock of course):
- Adafruit Industries USB to TTL Serial Cable
- Can be directly connected into male UART headers without extra jumpers
- Inland FTDI Adapter USB Controller
- Uses Mini-B, not Micro-B or Type-C
- Has 5 V/3 V switch
- Adafruit Industries FTDI Friend
- Uses Mini-B, not Micro-B or Type-C
- Adafruit Industries PiUART
- Designed for accessing the serial console of Raspberry Pis, but can be used with other devices with jumpers
- Adafruit Industries MCP2221A Breakout
- Requires soldering headers to the PCB
- You can ignore the I2C/GPIO stuff, the serial port function works by itself
All of the above options will work with 3 V systems (i.e. basically anything that runs OpenWrt). You plug them into your PC and they show up as an ordinary serial port. Use a terminal emulator like PuTTY and you're in business.

I will try this route. Thank you friend.
@mj82 - This is a great start to supporting this hardware. I did notice that lm-sensors could not pickup the thermal sensors on this board. I think the patches ported over from bcm2711 might need to be tweaked.
Also, what do you think about my 16k pagesize PR?
On my board lm-sensors detect fan speeds and system temperatures.

mj82's openwrt ^?
Yes OpenWrt from the link posted above.

I compiled htop with libsensors support yet the option to display the CPU temp is not available... sensors does work though as you pointed out... why does htop not?
EDIT: something wasn't selected. Rebuilding my .config gave htop with the functionality I expected.
I installed the pi 5 RTC battery and is working as expected, I unplugged the pi last night, reconnected this morning with the internet disconnected, time was kept.
# hwclock -r
2023-12-15 11:32:55.036617-05:00
To check the status of the RTC battery

Is there any update or ETC for official support/build of OpenWRT on Raspberry Pi 5?

status is in https://github.com/openwrt/openwrt/pull/13987
"when it's ready".
NanoPi R6s: two 2.5 Gbps interfaces; one 1 Gbps interface. Four A76 cores (like in the Raspberry Pi 5) and four additional A55 cores (eight cores combined). Want one? I have an extra I can UPS to you.
