Re: sudo apt-get upgrade interrupted - now won't boot correc

I did nothing to the SD card before running the Update sequence. It is a 16 GB card, which should be plenty large enough. However, the interrupt was not initialed by the Pi, it was my fault. I was using Putty and reviewing the progress when it asked about changing a "...RULES..." file. I should have...

sudo apt-get upgrade interrupted - now won't boot correctly

Folks....Raspberry Pi 2 running Jessie I was doing a sudo apt-get upgrade when the process was interrupted which returned me to a command prompt. When I rebooted the console log shows several "Failed" messages and it would appear that the rc.local is not being processed nor the networks file. Here a...

Re: How to detect corrupted file system

I guess I need to be a little more specific. First off I'm a novice when it comes to Linux. My Raspberry Pi's (a B+ and a V2) are running headless, so I do not get to see the information displayed on the console during boot-up. My Pi's are running Wheezy with a standard SD card (8 GB) and a 16 GB US...

Re: How to detect corrupted file system

OK, I will read up on fsck, but as I recall it is only good for Linux file systems. I'm sure my USB memory stick is FAT or FAT32.

Thanks....RDK

How to detect corrupted file system

Is there a simple command which will tell me if any part of the SD's file system or my USB stick's (auto-mounted) has been corrupted by a "non-graceful" shutdown? With Wheezy and attached to a monitor I could usually see the error or warning messages on the screen, but not so from PUTTY. With Jessie...

Re: Pi as wireless bridge?

Hi. Just got around to trying this as I have an application for a wireless bridge. No happiness here. I tried the "wait for network..." option in the Raspi-Config and the sleep 10 option in the rc.local (along with the other two commands). In both cases I get "can't add wlan 0 to bridge br0: operati...

Pi B+ SD in Pi V2 - will it work?

I have a working SD card in a Raspberry Pi B+ and I'm wondering if I can simply plug it into my Raspberry Pi V2 and expect it to work? That SD card is from the Wheezie distribution and is fully updated. apt-get update / apt-get upgrade... And, will the reverse work for a Jessie SD card from the Rasp...

Instructions for installing Jessie on Piv2

I'm working from a NOOBS SD which I downloaded from the Raspberry Pi downloads section. Are there any special steps for installing on a Raspberry Pi v2? Or a PiB+?

Are there any issues I need to be aware of? Thanks...RDK

When I join the "boot-up" session with a "screen -r" all is fine and I see the Python pgm running. I have a "try" loop running in the Python pgm which looks for a ctl+c se...

SD Card Corruption

Yes, there are lots of posts out there on this issue. So far I have not had the problem with my 3 Pi's, but I'm trying to think ahead. Aside from UPS power and surge protection, the other popular idea is the set up some of the filesystem as temporary RAM disks. This is proposed several places https:...

Re: Creating and using a script at startup

OK, I finally got back to this issue. I put the suggested script into the rc.local and it works. BUT,.... the resulting SCREEN session is only available to the root user, which, in retrospect, makes sense as it is in charge during boot up and thus when the command is processed. So, is there a way to...

The Serial Port vs HDMI for the console output

If I disable the serial port as per this reference (http://www.hobbytronics.co.uk/raspberry-pi-serial-port) so I can use if for other functions will it also eliminate the display I get on my monitor using the HDMI cable? Will the keyboard still function?

Re: Viewing the Startup Log when running Headless

OK, I tried out these suggestions.
