Encouraged by success with other tiny OS and bluetooth combo keyboard, I stepped neck deeps in code I have no clue, but learned alot so it suprised me on a google search to find this http://barryk.org/news/?viewDetailed=00322 I was doing the same mucking about in fatdog and they got same version to work just FYI I do not know where they store the patched source.
Only other difference was the file [etc/dbus-1/system.d/bluetooth.conf] obex related stuff
Code:
<!-- This configuration file specifies the required security policies

We all do it, but we shouldn't. Always RTFM !
"RPi 3 Model B Uncased Version:
This product should be operated in a well ventilated environment and should not be covered."
Of course, there'll always be some joker ready to sell you one of those cute little boxes to put it in. And, doubtless, sell you another board when yours burns out...

Update on cooling. It transpires that mini 5V 40x40 fans are often fitted to laptops. Won't need to look too far for a dead laptop! Otherwise, eBay has them for 99p from HK incl. shipping. Screw one to the edge of the plinth onto which you screw your RPi. No need to throttle a 12V unit. For extra sound suppression, run the 5V fan off pin1 (3.3V) of GPIO.

Thanks for your quick answer.

I have a general question about these puppies based on DEB packages. I should be able to install any apps through the Package Manager, right?
I tried to install apt-get. Well, did not manage to make it work. Here is the message:

If that's something easy to fix, let me know! Thanks


A couple of thoughts about this...

If you chose to update the package database in the Puppy Package Manager, that might be the cause. There might be an update of that lib that is causing trouble.

Quirky has it's own package manager, Puppy Package Manager. The Debian package management database and infrastructure is not there, apt-get probably won't work properly.

1. I have installed Quirky Xerus 8.1.2 in 16 GB. After installation, it shows two drive i.e MN0P1 & MNop2. mn0p1 shows 75Mb (vfat) and MN0p2 (Ext4) shows 6.8 GB. What happens to balance disk space. What went wrong?. After format it shows 16GB. Image written through windisk manager.


The first time you bootup, QuickSetup runs. The window has a checkbox with letters highlighted by a red background for maximum prominence, informing to tick this checkbox for the second partition to be expanded to fill the drive.

So nothing is wrong. You wrote an 8GB image to a 16GB drive, leaving about 8GB empty space. QuickSetup offers to fix this at first bootup.

@rameshiyer After we redo the factory default firmware aware fat to a different unsupported by firmware ext4 we lose much of the corruption support and will be faced with a increase in used blocks at the end of range being re-mapped for dead or near dead overused blocks at the beginning. Keeping unsupported ext4 and other non-vat at first half sized of listed size will keep the corruption level and base speed solid for the normal lifespan of a fully supported full sized in hardware orginal vfat.
So your setup as is is perfect, however would like to only fill first half my 32G which doesn't seem an option. Also would like a roomier first part vfat. Also if we resize the default fat to smaller than full size other than replacing it with a image overlay of fat, we keep the firmware support Wink and the speed boost. Have two identical sdcard from same lot, one is unchanged ( running fastdogarm, and a media version kodi that do not need unsupported image overlayed ) and still maxes out at 100MB/s where best I can get from this 22MB/s which is still fast to me Smile

You are right and I see the problem now...I managed to get rid of this error by installing a newer library (libapt-pkg5.0_1.2.15_armhf.deb) BUT I need now to create a new user (_apt). This is not going to lead me anywhere because adduser command doesn't exist (single user distro! ) Sad
End of game!

In the start menu there is a menu item to run the first run setup again,
even if you have already setup your system, so you can expand the useable space to be greater than 8 GB.

lol, right its really coming together with BKs vision, was reviewing stuff in the new kernel and its got so much neat stuff support compiled in and just waiting for use, the software defined radio stuff is there, joysticks, media like cdroms support there. I now can run puppy and download images from overhead satellites, track airplanes nearby etc. all those cool project that once needed a bloated RaspianOS are in sight.

Have powered up RPi3 with Quirky. It works, but:
Using an experimental layout of HW it was necessary to switch off - hard reset - a couple of times. This upset the booting procedure much more than expected, including a complete reset. During this stage, error messages overwrote the screen in several places making the underlying text unreadable. Something got written to the SD card, too which eventually rectified itself (I think). In my opinion, which may not be shared, I would like that an hard reset never writes to the SD card; maybe not possible?
After booting, there were too many options to run in the Quick Setup. In particular, selection of the video output default caused problems and freezing before it could be changed. Suggest the default is recast to always be AUTO.
There were some minor issues running the browser at first (not 'first run' related) but these also seem to have been cleared.
It was good to find Hardinfo retained because this is vital for HW experimenting. Thank you.
I fixed a small HS temporarily on the cpu, but it showed 50C in free air (no fan - yet). This confirms my recommendations above, viz. this system needs an heatsink AND fan combo, the former being affixed with a silver-loaded adhesive paint.
Otherwise, an interesting project all round.
For the record, I used a PSU like the one illustrated by BK on his blog and attached it directly to pins 4 & 6. This is an high quality switched-mode item by Cisco so I'm trusting that bypassing the on-board resettable fuse probably isn't going to be an issue.
There was some 'hash' on some areas of screen, hdmi, which did not go away. My hdmi-vga converter, sold for use on RPi B+ didn't work - it does on B+ and Zero.

Now, I'm away to get my Christmas lights coupled to a motion detector and the door video-phone to activate using the GPIO pins.

Sad!

PS: Please can we have a completely updated image. Some of us aren't too hot fixing SW!

@sage I had similar but not as bad experience, check your fstab file in /etc for a malformed mount of root, BK says the upgrade does not touch fstab ( which I did check, he is right OF COURSE, but its been malformed since 8.1.1 ) the new kernel has a issue with that where last versions somehow worked, ( I can't see how /dev//sdb2 never existed for me ) with new kernel all versions back to 8.1.1 freeze unless changed.
Second, it is possible to run without sdcard, with either two methods I posted for you a few pages back, Dons ideas and Patks. My method is easiest, and moves root to a usb spinning harddrive so boot sdcard is removable.
On the heatsink front, The fanless metal case has worked well enough for me and I have run some CPU swamping software and played high bitrate full screen max res videos at same time, even case upside down (wifi issue work-around) it never got hotter than mid 50C

Many thanks, TXD. Your first two paras are outside my ambit - I do HW!
As for mid-50C, in my opinion it's too hot bearing in mind the physical size both of package and features inside package. The instructions are clear. Putting it in a case probably violates your warranty! No case to answer, so to speak!

@Sage yeah right no one going to believe you do not know your way around a keyboard, text editor and that soft-mushy stuff called software, look at BK blog he is off on a multi-day massive compiling bender so quit pretending you need BK to roll a 8.1.3 clean image. Rolling Eyes
We ain't buying ( OH I AM JUST A HARDWARE GUY, DERP DERP!) Wink

Yup, and I don't believe folks 'round here don't know which end of the soldering iron to hold and things like fitting heatsinks...

Ah, yeah your right.. I have more soldering irons than radios Wink But I am horrible about burning and cutting my fingers on sharp metal so not much desire. Heck last night I cut my finger on a plastic fake pineneedle.
