config.txt file on Raspbian NOOBS?

Fri Dec 29, 2017 1:44 am

Hi, I recently downloaded Raspbian NOOBS onto my SD card, but when I saw a video showing me how to use a VGA monitor with a Raspberry Pi, I have to edit the code in the file config.txt. When I went to my SD card, I did not have anything named config.txt. Can anyone help me find the config.txt file? I formatted my SD card, removed partitions on it before putting Raspbian on it, and it still does not work. There is no other way that I can make the Raspberry Pi boot up at the moment. Any help would be appreciated.

NoobS is a installer / chooser and when you have installed an OS you use the NoobS "Edit Config"

https://github.com/raspberrypi/noobs/bl ... /README.md

Regards VGA you need a converter, something like these:

https://www.pi-supply.com/product/hdmi- ... pberry-pi/

https://www.modmypi.com/raspberry-pi/ac ... -convertor



I am at a loss why NoobS is needed IMO it is just easier to use Raspbian Stretch with Desktop and create a bootable SD Card with Etcher

I looked at the websites, and I have the converter, but I need a little help on getting to edit config. How can I choose the OS? I can not boot up my Raspberry Pi without my VGA display.

The HDMi-VGA should just work without configuration.

What are you using to power the Raspberry Pi ??

A micro USB to USB charger. I plugged it into my computer. I also tried using it with a 5v wall outlet adapter.

That works OK with RPi1B, RPi1A, RPiB+, RPiA+, RPiZ.
It's going to be marginal with RPiZW.
It's not going to work well with RPi2B (mod1)
It's totally unsuitable for RPi2B2 or RPi3B.

Even with the working machines you may not have enough left in the power budget to drive a HDMI to VGA adapter.

A PC USB3 port will supply 900mA, whilst USB2 500mA maximum and therefore underpowered:

1) A ('phone) charger is not the same as a power supply in that, whilst one may be marked, say, 5V 2A, there's no guarantee that it can provide both at the same time ie. at currents >1A many such devices' voltage falls below the minimum recommended (low voltage threshold) of ~4.6V for a pi (esp. a P3B)
2) Most (USB 2.0) ports on a computer can only supply ~500mA (AIUI USB 3.0 ports can supply a higher current but probably will not be switched into that mode by the lead connecting such to a pi.
3) It depends what you mean by a "5V wall outlet adapter" (and, maybe, where you are) - mains sockets with USB charging ports (or similar, pass-through, adapters) are becoming more common, but are, in essence, chargers rather than power supplies (see 1).
W.r.t. to NOOBS' config.txt, IIRC the NOOBS installer does not normally require/use one itself but, as has already been mentioned, provides a built-in editor to edit those it creates for the O.S.'s it installs. It's default video modes are selected by pressing/toggling a numeric key (1, 2, 3, or 4) during (first) boot, and one of those is a "low-res" HDMI mode which should be supported by most, if not all, current HDMI-to-VGA active converters (HDMI-to-VGA cable adapters are not active devices and will not work). If "toggling" an appropriate numeric key does not work (historically this has been an issue with some wireless keyboards not being detected properly) then either, if you can, try a different keyboard, or, with a simple editor (notepad+, nano) try creating a config.txt on the first, FAT32 partition of the uSDHC card. NB. on most Windows computers this will be the only visible partition.
Trev.
Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm
