Re: install OS on Processor

You need some sort of permanent storage, the Pi itself doesn't have any. So it uses the SD card. There is a compute module variant that has onboard flash, but that requires an extra carrier board. You can boot from a USB attached HD/flash drive if you wish, without the SD card. But that is still ext...

Not the touchscreen change, that is in 4.13 [sic], not 4.9.
Hang on, I though BRANCH=next was taking us to 4.14.
Just so happened I did the work on 4.13. It will get cherry picked to 4.14 quickly, if not already.

Re: PiZeroW unrresponive to ping/SSH but still operational - Mystery!

Networking has dropped out.

We are currently investigating various Wifi issues, could be one of those.

Make sure you are running the latest Raspbian, can you try the full version to see if there is any difference?

Worth noting that the entire module is powered off the 3.3v supply going up the ribbon cable, which might be pushing it a bit.

Hmm, not sure you need to backup and entire SD card just to backup a few bits of source code.. Keep a single SD image of your base system once its set up. The use rsync to backup the variable stuff.

Re: Raspberry Pi dedicated touchscreen error after update and upgrade

When did you do the update? We just merged a change to the touchscreen driver which I thought should work OK..

However, even if it wasn't working I would not expect the list of errors you have got here.

If the CPU is 100% , there is not much you can do. I suspect ElasticSearch, running as it does in Java, is simply too much for the Pi to handle.
