You can also look at my NOOBS enhancements called PINN at https://github.com/procount/pinn/blob/master/newfeatures.md where I will eventually integrate NOOBSCONFIG to make it even easier to use.

Re: Request for official Raspbian image: execute script at b

We have the same goal. You can use it headless too. If you only want to install one OS, you can configure it to install that one OS only on boot - no interactivity required. See https://github.com/raspberrypi/noobs#how-to-automatically-install-an-os . And noobsconfig will still customise it as you w...

Re: Installed Official 7", now I can't get HDMI to work

It sounds like you are using NOOBS. So you actually have 2 operating systems installed. First the Pi boots into NOOBS (a very basic linux os) and displays on the HDMI screen correctly according to your display_default_lcd=0 setting in the config.txt file in NOOBS. (EDIT:Actually the current version ...

Maybe try putting the 19V dc power cable through a ferrite core? *shrug*.

Re: (Capacitors) Any electronics guru's hanging around??

The size of the capacitor required (C) is dependent on the impedence/resistance (R) of your laptop, how long an interruption (T) you wish to withstand, and the minimum voltage (Vmin) required to sustain the laptop in operation. As soon as power is removed, the capacitor will start to discharge expon...

Re: (Capacitors) Any electronics guru's hanging around??

A similar issue happens with users of Motorola Lapdocks when the screen is closed - it disconnects the USB power to the RPi momentarily causing it to reboot.
Some people used Supercapacitors ('supercaps') to ride out this interruption.
You might find some solutions if you google for the above issues.

Re: Noobs Install - Add others for offline install

Thanks. I like to think of PINN as more of an enhancement than an alternative to NOOBS ;-) VNC is already included in NOOBS. It is largely undocumented, but there are references to it on here and in github. Add 'installvnc' to recovery.cmdline and the output will be on VNC instead of your monitor. I...

Re: Noobs Install - Add others for offline install

There is a limit of about 4GB on NOOBS to store the compressed images because of the requirement to be able to install RISC_OS and it's unusual file system, which is why the other OSes were dropped from the full version as they increased in size. So any "NOOBS Heavy" would have to omit RISC_OS. With...

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

Code: Select all

root=/dev/mmcblk0p6
might be key to the problem.

When installing your 5" LCD you probably only want to add

Code: Select all

fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo
to your cmdline.txt, rather than replacing it altogether.

NOOBS (1.4.x) uses an old kernel and old boot files that do not yet support the 7" touchscreen display. However, if you copy the bootfiles from Raspbian Jessie onto the Recovery partition, the NOOBS recovery program can be displayed on the touchscreen. The touch interface still won't work as it need...
