Old updated SD card RPi 3 no ethernet

Do I need to do something special to get my old SD card to boot the RPi 3? I have done: sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade But the lights on the ethernet port never turn on. They did turn on before I did the sudo apt-get updates though?! I have no monitor connected to...

Re: BCM2837 datasheet?

I wonder this too, seems they are still on 40 nm if you google = heat problems.

Really the bus and memory needed upgrading more than the CPU = new platform.

Re: Early RPi 2 randomly segmentation faults process

Just to follow up now I'm suspecting it is the SD card after all. When I had the power outages (not good for SD cards BTW) the following script was not run: swapoff -a sysctl -w vm.swappiness=0 Basically maybe the swap partition has taken a hit after being power cycled in use after the first failure...

Re: Early RPi 2 randomly segmentation faults process

Exactly, so I'm trying to figure out if it's a one time freak occurrence or if others with early RPi2 from the white black latch factory are seeing failures too after 1 year of 24/7 operations.

Re: Early RPi 2 randomly segmentation faults process

So the white latches are just to point out it's one of the first RPi 2 out of the factory. And not the same factory as todays RPi 2, the metal on the HDMI port is different too (matte aluminium instead of dark shiny). Edit: Precisely AndyD. I have changed nothing, it has been running flawlessly for ...

Early RPi 2 randomly segmentation faults process

The RPi 2 I bought directly after release from pimoroni has started behaving weirdly.

It has black camera and screen latches instead of white.

Anyone had the same experience?

My other 4x RPi 2 (white latches) are 100% stable.

Just to complete the picture, the Rift or Vive are never going to run on a raspberry pi. They have closed source hardware drivers.

Re: Processing 3 is running for the first time on a Raspberr

Sweet! So does it only support OpenGL 2 or can my game http://aeonalpha.com that uses OpenGL 1 mostly (I use shaders for VR barrel and chromatic aberration) run on this. Is it hard to port this to LWJGL or do I need to switch to JOGL? BTW if this can run old OpenGL I'm going to build a Pi VR headset...

Oh, in that case it's "safe". It's on the top of a 2 meter bookshelf. You should see the similar 150W power supply next to it! Closed plastic PSUs last about a year on full blast, these open metal ones last at least 5.
