Pi4 Firmware?
#1
Hello,

I just receive my pi4 last week and trying moode 6.2.1.
First of all pi4 runs pretty hot, even at idle. As I see raspberry released a firmware which fixes usb3(?) power consumption and lower board temperature a little bit.
I would like to try that, but I'm not sure if this firmware update breaks my moode or not?
If it's ok to update firmware, is there any special repo to add?

Anyone has any experience about this?

Thanks

I'd recommend buying suitable cooling like the Flirc case, I don't think any Pi since the Pi2 has not required cooling to avoid hitting the SoC's thermal limit under load.
That said, like the others, the Pi4 will not be damaged by running without cooling, it'll just hit the thermal limit (~80 celcius) under load and be clocked down by the govenor to stay within that thermal limit affecting CPU performance accordingly.

My primary concern is not temperature related. It is power consumption related. Tests shows lower current and voltaje consumption (60ma and 0.3w more or less).
For headless job as moode it will be around max 60C which is ok to me...

It doesn't break Moode.

Nor does the new boot firmware updater.

Cheers,

Procedure to install the Pi-4  f/w update is below.
Code:
sudo wget http://moodeaudio.org/test/vl805_update_0137a8.zip
sudo chmod +x ./vl805
sudo ./vl805 -w vl805_fw_0137a8.bin

sudo reboot

Thanks for the link. I found another, more recent firmware from raspberry foundation;

"We have received an updated USB controller firmware from VLI. This firmware enables PCIe APSM and should not have the device hang issues seen with the 0137a8. It should also resolve issues seen with poor performance when single USB2.0 devices were intermittently transferring data."

Nice, thanks for the heads up :-)

Hi All,

I thought I would try the firmware. It dropped my temperature by a massive 1 degree, from 52 to 51 degrees C. I have a fan and huge heatsink.

@starbender - Understand you are not worried about temp, but I thought I would just list my experience.

Is there any inbuilt command to verify Power usage?

Thanks for the info.
If you mean current usage, you can't. You need to check it with ampmeter.
If you want to check voltage usage;

vcgencmd measure_volts

edit: my pi4 sits around 59-60 C with passive small heatsink and mounted vertically..
