I have a pair of tweezers handy for exactly that purpose - especially useful for the official display.

Am i the only one experiencing garbage on the serial port? (i mean the gpio rx/tx pins) - cable is good since it works fine on my raspi2.

I am testing with the latest jessie image, and after logging via ssh the board seems fine.

Another question: is there a way to disable _forever_ the wifi / bluetooth? I noticed that, upon boot, wlan0 is always up (as is bluetooth) and removing these lines from /etc/netwowrk/interfaces:

allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

didn't make any difference.

Out of interest, what is that option? I can't see it documented anywhere (at least, nowhere that Google has spotted yet) and I'd like to play with a 64-bit Debian.

You'll still need a a Pi compatible kernel, built for 64-bit (which doesn't currently exist), but if a kernel dev wanted to work on this, it is possible.

Is anyone using the Pi 3 with a wireless keyboard ?
I would like to use the onboard wifi for a network connection and use a wireless keyboard & touchpad as well but I was worried about possible conflicts or interference.
If anyone knows of a keyboard that works (or knows that I am worrying about nothing) please let me know which

I'am trying to add support for the WiFi/Bluetooth in DietPi for the RPiv3. Unlike OSMC/OpenElec/UbuntuMate who most likely had this information prior to the RPiv3 release, i'am having to play catchup :)

From what I can tell, there is a new .deb package that isnt available on the Jessie repo, yet exists on the Raspbian image:

No. It's probably not complete garbage. It seems to be login prompts cycling through different baud rates (as if it's trying to auto sense).

Drill a hole in the card and put a bit of string through it so you can pull it out.

I'm sure that will work....

a "tag" made of tape works better, and can be folded up flush with the case.

Like this ?

That is a bit of a sticky label folded back on itself so it sticks to both sides of the card for extra strength.
Great minds etc etc :D

Just to be sure that I am on the same page. Does this change means that the PL011 is not available anymore on external header pins 8/10 ?

This seems to mean that the default "ondemand" governor is now unusable if you use the serial line ?

CSI lanes?

Is there anyway to expose the extra lanes.... or have these already been on in the Pi3?

Thinking of the replacement camera module, and higher FPS feeds to feed the now faster VC4.

specifically looking at 720p60 (really really this time) 720p120 and maybe like 1080p50 or 1080p60. or even the 480p240 ?

We are operating EnOceanPi's on our RPis.
Could it be possible that this modul generates a conflict with the WiFi modules or BT on the RPi3?

Not so much a question but more of a tip for Pi 3 owners that use a case..

I use the Flirc case and with the new non latching Micro SD card reader implemented on the Pi 3 it's almost impossible to get the SD Card back out without taking the case apart or poking at the SD card with a pin and needle nosed pliers (pretty sure that's not going to be great for the health of the SD card) so you may want to think about buying a micro SD card extension cable.

Another alternative is a bit of paper taped to the card to pull it out. Right now I am using tweezers to get the card out, but will probably switch to the tape... has the advantage of being able to label cards.
