Re: Proposal: Raspberry Pi Zero W with 2GB / 4GB embedded

For jamesh: hey I say that the idea is simple, not that it will be simple to do it :) !!! By the way the Jessie Lite do already fit in less than 2GBytes, so one of your points is already solved. And by the way I am talking about applications without monitor, keyboard, etc., a lot of Zero and ZeroW a...

Re: Proposal: Raspberry Pi Zero W with 2GB / 4GB embedded

I see from some tones that some people maybe didn't got the spirit of what is just a proposal (and for an additional edition that wouldn't certainly remove Zero and ZeroW). Maybe also not the target. In any case, first of all it is useful to think about it. And in order to think it is useful to talk...

Proposal: Raspberry Pi Zero W with 2GB / 4GB embedded

This is a simple and effective idea for you Raspberry engineers :D Like a lot of other people here, I am using the Zero or ZeroW for small hardware applications, where I am usually fine with Jessie Lite and 2GB of SD (actually most time I don't ever expand the image to fit the full 2GB). The problem...

Re: How-To Create a GPIO Halt Signal

Thanks! Let's see if I understood, and one additional question. Recap: My power-off/power-cut circuit needs a 0 for some milliseconds, this only at shutdown when the system can be safely shut off. If I understood correctly, to have this for GPIO#8, I simply add to /boot/config.txt this line: dtoverl...

Re: How-To Create a GPIO Halt Signal

Addenda: I'm using Raspian Jessie Lite (but as you can see from my first post of today I was able to find info on this only on FreeBSD)

Re: How-To Create a GPIO Halt Signal

PhilE please better explain. I don't have a complicated ACPI power system. I just have a system where I can cut off power basically with a 0 (I am still undecided if to use any common Push-Button power off IC or another circuit that I designed). You wrote that editing /boot/config.txt with dtoverlay...

Re: How-To Create a GPIO Halt Signal

It seems this is an issue of Free BSD "On Raspberry Pi, GPIO output pins retain state on halt" https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211979 I added a comment to say that it would be handy a conf file or other one-time setup (SIMPLE!) in order to have a behavior like this (for example) GP...

Re: Disabling login prompt

I need to just remove the login rather to disable. My Pi will be the controller of a small hardware without keyboard. Now: $ sudo systemctl disable [email protected].service correctly replaces the commenting out of /etc/inittab that was #1:2345:respawn:/sbin/getty 115200 tty1 now I want it automatically lo...

Re: Removing Login from startup

I am running everything in base console mode as it is really a basic project; I want to start the Pi without a login, and it must start a shell script. Past instructions was: a) sudo nano /etc/inittab disable this line = # at the beginning of the line to comment it out #1:2345:respawn:/sbin/getty 11...
