Re: Sound & latest updates...

Hi, Check your sound configuration , you may be able to set your audio sound card playback interface rate at another value than 16000 Hz. There is no /etc/asound.conf on my system. On my side, I'm just using the PI3 jack output for speech synthesis. Testing with : speaker-test -r 22050 or 16000 soun...

Re: Pi4 && Aeotec Z-Wave USB Stick Gen5

My opinion is that it's not a fault of the USB chip to refuse to talk to a device that could potentially fry the port logic. This device have an internal battery to allow standalone in-place z-wave associations with remote modules that may be too far from the machine hosting the home management stu...

We are still thinking about how, if we were to go ahead, the CM4 would work, as as stated above, there are not enough pins on the SODIMM connector to expose everything. + Ethernet GMII should be there also to allow SoC controller to drive an external PHY...

Re: RISC-V

In that respect RISC V has been doing very well for quite some time... I think we must be careful. I was quite sure, by the end of the 1990's, PowerPC would be x86 killer. A newer&clean design, already thought to evolve nicely to 64bit (no need for another instruction set: Hello ARM!)... But IBM op...

Re: RISC-V

Always worth remembering that this stuff is very niche, as in, sales are low compared with x86 or ARM, so comparing with ARM or x86 space is a bit apples and oranges. Your question was indeed "why x86/ARM" does not do the job in critical SW applications, not epsilon market shares (for now). For thi...

That's really a kernel logging question. All we do is put a critical message in the kernel log. What the kernel does with it after that is down to the kernel.

Anyone can change the settings in the driver itself. I'm don't have time to incorporate some sort of device tree settings stuff, so that will have to do until someone else steeps up to the plate. That'll will always be better than current log-spam. But to tune this, a sysfs entry is more convenient...

Yes, the 5V to 3V3 conversion keeps working, even with inputs as low as 4.0V, but that is not the whole story! The SoC itself also uses 5V directly, HDMI uses 5V, and thus so do external HDMI to VGA adapters. Most importantly all USB devices (keyboard mice etc) use 5V directly. So no the PI is NOT ...

ALL forms of data storage are prone to complete loss of data. SD cards are no different. If you want (near) 100% availability, use ucarp and rsync or something similar. Do you understand that, with specific hardware controlled by the PI, this would also double all the associated devices (for ucarp)...

It' isn't a big problem if you have a backup/restoration plan (and the backups!). Plan ahead!
