picore 8.1.5 rpi3 boot codes
« on: May 05, 2017, 09:43:48 AM »
The answer is probably so simple that I'll feel foolish, but how the hell do I enter boot codes for my rpi 3? Install was easy, boots fine but I can't access anything by hitting f2, f3, or f4 as suggested.I'd like to get this thing configured, but with my clinical depression being what it is I just don't have the patience or inclination for a lot of trial and error.


I'm not sad, I'm depressed - there's a difference.

Hi,
You have to edit  cmdline.txt  on the first partition of your µSD card.
Or  cmdline3.txt  if you're using a RPi3.
Download a copy and keep it handy: Core book ;)

As I can't seem to find such a critter on my rpi3, and considering that said file would be accessed in order for piCore to boot, I'm going to have to assume I need to do this "offline" That is, remove the card from my rpi, stick it in my card reader and pop it into the usb slot of some other computer, like my lappie.

As I can't find the file I'm guessing that's the way to do it. Thanks for the tiip.

Hi Captain.Midnight

I think that partition gets unmounted after booting, so you probably have to mount it to access the file.

I really couldn't say for sure. I'm quite new to picore so I was probably doing something wrong. What you say sounds right though. As the card is unmounted after boot it IS offline. Perhaps if I had actually installed more than just the GUI, say an editor, file manager, etc, I would have been able to find it, so I did put it in my lappie. Hopefully my depression will lesson by tomorrow, I've really had enough for now (connectivity, not picore) so I'll make the first in a long series of mistakes and then I'll try it your way.

Let's mark this one as solved.
