Re: 4B/Buster - usb usb2-port1: Cannot enable. Maybe the USB cable is bad?

And did that work? Does squeeze do better? Good question!. I can not say if squeeze is beter or not. All I can say is since reverting to squeeze the problem has not occured with the test camera. This may, of course, just be a co-incidence. Other cameras still show the problem. Some maybe 1 or 2 tim...

Re: 4B/Buster - usb usb2-port1: Cannot enable. Maybe the USB cable is bad?

Has this been fixed yet? Since upgrading to buster several of my pi zero W are reporting this and disabling the attached usb camera. So it's not just one pi / cable / camera but several ! it appears to occur after a spurious read error from the usb device. I'm up to date with software: root@cam2:~# ...

Re: New AWB algorithm in test firmware

How about never update a running and critical system unless you tested the update first on a non-critical system? That would be my favourite. How about "Just let the customers do the beta testing" or "if it ain't broke don't fix it". :) If you would like an experienced QA manager I can come out of ...

Re: New AWB algorithm in test firmware

This was fixed some time ago. You need to set -awb greyworld on the raspistill/vid command line.
But as I wrote.
I'm running motion, not raspistill.

running "vcdbg set awb_mode 0" kills the wifi. This is bad as the pi zeros are headless.

Re: New AWB algorithm in test firmware

Which is why I had backups.
I've been in IT since 1975 and "restore from your latest back-up" was my favourite support reply.

Re: New AWB algorithm in test firmware

I don't use thumbnails. This is the "purple haze" problem reported elsewhere. I'm using the 8Mp NOIR pi cams with no filters with Pi zero W and the motion s/w package.. Examples of before and after the recent update can be seen here on a camera that is lit only with IR leds. http://www.nevilley.org....

Re: New AWB algorithm in test firmware

Ran apt upgrade on 10 Pi zero W running motion over the weekend. Those that use the Pi NOIR cam now have a purple haze. Those running under IR light are unusable. I don't know why but running "vcdbg set awb_mode 0 " appears to kill the wifi ! For headless PIs this is a problem. As these are security...

Re: picam colour wrong after apt upgrade

Thank you for the reply. I have tried the fixes posted in the other threads but sadly they do not work for me. The reason being the wifi dies when I execute "/usr/bin/vcdbg set awb_mode 0 " Being headless units this is a bit of a problem. :( I am now in the tiresome process of recovering the sd card...

picam colour wrong after apt upgrade

Hi been using several pi w with pi noir camera for a few years now running motion software. Two of these are inside closed boxes (one bird nest and one hedgehog hotel) and are illuminated by infra red LEDs. This has produced monochrome images for years. However, after doing an "apt update; apt upgra...

Re: A sign of the times perhaps

I would contact the Norwich Jam organisers directly; it may be that they were not aware of what security were doing, or that there were a problem in this respect. Emails and Fb posts were made when we got home to both the organisers and the venue. A Fb response from the venue agrees it was wrong an...

Re: A sign of the times perhaps

I was at the Norwich Jam and was aware of security checking people's bags on entry - which is understandable - but wasn't aware anyone had been refused entry. What was in the bag that they wouldn't allow in? Two maplin kits that my wife had built (she's a novice constructor) - one a "retro FM radio...

A sign of the times perhaps

A quick heads up for anyone organising a Pi Jam in the near future. Make sure any venue security is aware that visitors will be bringing projects along with them. My wife and I were very disappointed to be refused entry to the Norwich Pi Jam on the 27th May because we had projects with us to show of...

Oh boy!
Yup just a few (dozen) upgrades to do.

Thanks for that.

Now where do I have to monitor to know when to do that again?

no upgrades for months (solved)

Hi, I ssh into my pi every week and perform apt-get update; apt-get upgrade; as root. This worked fine for many months but for the last few months I get a result of: "0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded." Have there really been no updates/upgrades or has somthing on my pi g...

Re: Norwich Raspberry Pi User and Developer Group

Well, I've bookmarked this meeting in my calendar. Unfortunately it clashes with my regular monthly mensa meet so I'll not get there until sometime after 2. :cry:

I'll probably have to bring the geekette with me but can not bring my Pi as it's running 3 websites 24/7.

Nev (yes that one)
