Re: Reload NOOBS if screen freezes/ kernel panic /5"LCD[SOLV

Well, not sure how I missed this but after I made the last change the touch function of the screen stopped working. Just FWIW. I think I'm just going to leave it disabled at the moment but know I can just revert back to the working cmdline.text if needed.

Re: Reload NOOBS if screen freezes/ kernel panic /5"LCD[SOLV

It's all about partition arrangement. If you put plain Raspbian on your SD card, then /dev/mmcblk0p1 will be the boot partition and /dev/mmcblk0p2 will contain the root file system. (Maybe the setup program assumed this arrangement) If you install Raspbian from NOOBS, then the partition arrangement...

Re: Reload NOOBS if screen freezes/ kernel panic /5"LCD[SOLV

I think changing root=/dev/mmcblk0p2 to root=/dev/mmcblk0p6 might be key to the problem. When installing your 5" LCD you probably only want to add fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo to your cmdline.txt, rather than replacing it altogether. I tried that and it seems to work perfect as w...

Re: Reload NOOBS if screen freezes? Shorcut?

Okay, here is the "fix" that I came across. To recap, it was a new RPi. Newly installed OS via NOOBS download. Everything worked fine. Tried to install a Waveshare 5inch touch LCD. Followed the instructions online, from the included CD and from Youtube Video. After I installed the software to activa...

Re: Reload NOOBS if screen freezes? Shorcut?

I screwed the pooch on this one. I accidentally deleted the one that wasn't working. I feel confident I can repeat the error though and post the results. The cmdline.txt that works is as follows: dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=de...

Even a Blind Pig Finds a Truffle Once in a While... Think this will work or did I just start a bunch of other problems? So far it appears its all working.

Re: Reload NOOBS if screen freezes? Shorcut?

I actually tried this too.

fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)

Could this be a zero-length partition?

Hello, I've been at it for a bit and still haven't had much luck. I'm finally tied in via Terminal/SSH and have the RPi working good.

Currently I have Raspian running on my RPi from newly formated SD card. I also have the SD card that supposedly has errors on it in a USB adapter plugged into the RPi. I changed the directory to the 'media' USB and now not sure what to do. I tried sudo fsck /dev/mmcblk0p2 and it said "could this be ...

Re: Reload NOOBS if screen freezes? Shorcut?

Get a new SDCard, build a copy of Raspbian on it and you have a Linux system that can be used to rescue the borked system. You're saying just put Raspbian on a new SD card and insert that into the RPi and run the OS. Then add my messed up OS/SD card into a usb adapter and put into the RPi and acces...

Oh man, I really don't know what that means? Any further direction would be much appreciated. fsck? Sounds close to what I was thinking.

What screen are you trying to use? Does the RPi boot NOOBS/Raspbian normally if you remove the screen and connect it up to a HDMI TV? Trying to use the Waveshare 5 inch HDMI LCD.

If you are connect to your Mac via the USB, do you still need wifi dongle or Ethernet connected to get updates and have network access?
