I use berryboot to compare the various distros. It saves having to have a
lot of SD card on hand.

It should be possible to make a berryboot package for fatdog arm
but nobody has gotten around to it. Crying or Very sad

don570,
I have recently purchased a pi3, so keen to try armdog!

I followed your instructions on page 1. Created a fat32 partition on my 16GB SD card, starting at 8MB, then copied all the files onto it.

But it won't boot. I just get a big rectangle with rainbow colours in it, and another small rectangle at top right. Then nothing happens.

the rainbow top right is an insufficient power warning

iirc a 2A power source is recommended for the pi3

I also own a pi2, so obvious thing is to try that, and yes, it boots!

So, something needs to be changed for the pi3.

Thanks for that info. Yes, I only have a 1A supply.

Ubuntu-Mate still ran, despite the under-voltage.

I use a 2.1A tablet charger and haven't had any under-power issues on my days old RaspberryPi3 currently doing a looped playback on mine to see if it will break before 30 day full refund window (shipping box was very abused ) Crying or Very sad
Yet to try the Fatdog version but a up-todate full 64bit puppy version would be great. hint-hint Wink

Quite a bit of discussion about non-booting RPi-3, not necessarily a power issue. Detailed discussion is out of my range but seems some mods are need to the SW and multiple attempts to boot.

Incidentally, my early Berryboot with Puppyalpha4 still runs fantastically well on B+. Just wondering whether BK could port that over to the RPi -3 64bit ARM iteration? [-and, separately as a single .img, the Zero].

For a power supply to my raspberry pi2 board I use a modified tablet power supply.

I cut off the barrel plug and substituted a micro USB plug.
I checked for 5v with a voltage meter.

Here is my config.txt file.
Note that I must put in the following because the audio stutters otherwise...
hdmi_ignore_edid_audio=1



Code:
disable_overscan=0
start_x=1

I was able to make a second card work with omxplayer
so it's looking good. Bad news I broke my mouse somehow.

I thought berryboot kernel would work with rpi3??

Discarded Cisco switched mode PSU from a Virgin (Sky?) box will supply 5V @ 3A. Should be sufficient to run plenty of peripherals, probably including a bank of analogue converters and relays for projects.

Don't think the ARM6/7/9/11 architectures are compatible apart from being 32 or 64bit? BK will know.

there is a different firmware loaded for RPi3 but software wise backwards compatible, there was a long black screen on the media OS I am currently running during boot and not the normal loader messages, liken it to the long boot darkness of changing between BIOS and UFI boot-loaders.
I haven't seen any noticeable speed changes, audio is different or my ears are playing tricks (music and effects louder dialog is muted, etc ) Wink can't see why that could occur with HDMI

I made an important upgrade --- Samba and OMX player is now included
inside the package.

File system has been squashed into one file using the command ....
Code:
mksquashfs squashfs-root fd-arm.sfs -comp xz -Xbcj arm -noappend


Also some minor improvements as well.
geeqie and puppy units now work properly.

Now boots directly to desktop because there is no save file.
If you want a save file you can set this with the control panel.

Instructions on first post.

PostPosted: Tue 19 Jul 2016, 19:55    Post subject: Xming and putty for remote control of raspberry pi 2  

I was able to get Xming X server to control the raspberry pi2 computer remotely.

I could even get the raspberry pi 2 to play music
(remotely controled by windows XP).

With omxplayer installed the rp2 will play a video (with sound)
on the HDMI monitor of the rpi2 fullscreen. Cool

Check youtube videos to explain how to use Xming.

DropBear needs to be running on the raspberry pi.
Set with the control panel.



Xming must be running on windows XP,
(Xlaunch.exe will set the window options, it's part of the xming package)
then...
Putty makes the connection to the rpi2 over ssh.
Then login as root , password woofwoof

Then you can launch rox or any gui program installed on the rpi2.

RPi getting very complicated with ARM6/11, 7, model 1, B, B+, model 2, model 3, 32bit, 64bit and now availability in limited quantities of Zero, but only one per punter.

Not sure whether it's your bag don, but a ZeroPup/Dog, albeit 32bit, would be a master stroke, especially with strong terminal options and comprehensive dongle networking drivers (doesn't have on-board NIC). It's 1GHz with 500Mb so putative strong performer with most Puppy incarnations except FD64, albeit with the intention of device control being a principal objective.

{Anyone writing about HW for Zero and RPi s, generally, on this Forum? The 'official' blurbs on the InterWeb are useless invocations to buy ready-made plug-ins. [Appreciate any links to basic hard wiring projects together with operating code, either here or by PM].}

-Corrected some right click icons

See this command for more info

There is no savefile by default, however you are asked if you want to create
a savefile when you quit. Here is some info to read about savefiles.
It applies to fatdogarm as well as fatdog.
