Re: what is needed for Vk-172/Vk-162 Cold Boot

How many satellites was it seeing the last time you used it? If it can't see enough satellites, it won't cold boot.

Re: Raspbian NTP clock synchronisation- how often and where?

Look at the minpoll and maxpoll settings in ntp.conf. "man ntp.conf" says: minpoll minpoll, maxpoll maxpoll These options specify the minimum and maximum poll intervals for NTP messages, in seconds as a power of two. The maximum poll interval defaults to 10 (1,024 s), but can be increased by the max...

tty related - but serial tty, that is - it's really helpful if the user is added to the dialout group that owns the serial devices. Maybe that's what you were thinking of?

testing ≠ development. Pixel and the various Debian-based distros I've been using (usually at newer than stable) since the late 1990s have been pretty solid. Guess I've been lucky.

Re: UTC-time in RPI? Good method?

as epoch1970 (eponysterical!) says, the system clock is always UTC. So any RTC should also be set in UTC. Since your computer is on a network, it will likely also be running NTP which also assumes UTC. So doing anything else would be fighting against a whole bunch of system settings. Why create work...

They've only got a much smaller amount of RAM; something like 64 K. Maybe a bit too cramped for SmallTalk

Re: Unable to locate package

These aren't Raspbian repositories, and most of the binaries aren't for armhf. You may have to build from source: please see https://github.com/analogdevicesinc/libiio and Building on the Linux Host Target for more details.

You should also take that line out of your apt config file.
