Re: Automated OpenVPN Server Setup Script

i setup a pivpn box and managed to connect to it correctly using openvpn for mac (which i installed using homebrew) when i try to connect from another raspberry pi (under exactly the same conditions as the mac) using openvpn (installed via apt-get install openvpn on the second pi) i get errors as sh...

Bare Metal HW-RNG

Been trying to find some information on using the HW-RNG on the raspberry pi 2 in c / asm. i tried searching the linux source for a hardware specific version of arch_get_random_long() (see below) but can't seem to find one that would be the right one. https://github.com/raspberrypi/linux/search?utf8...

Re: Raspberry Pi 2 (bcm2836) multi core

Thanks for the prompt reply. I managed to get it working, as per the information posted. it turns out i had an issue with setting the sp incorrectly for each core. once i sorted that out, it worked a treat. i now have 3 cores (Wynken,Blynken & Nod) fighting over led's to flash, and incrementing a me...

Raspberry Pi 2 (bcm2836) multi core

I was looking at https://github.com/dwelch67/raspberrypi/tree/master/multi00 which states in the readme: So thanks to JS2 in the raspberry pi bare metal forum for the info Not sure where or if this is really documented. But if you write to address 0x4000009C for core 1 0x400000AC for core 2 0x400000...

The next version

Ok, this question might have been asked before, but....

Will the good folks at raspberrypi.org be releasing a raspberry pi version 3?

Or will they be going straight to version 3.14159265358979323846264 ?

I mean, it must have crossed their minds, surely.

Re: Cross Compile Tool Chain Distros

Cross Compile Tool Chain Distros

Not sure if this has been suggested, or even better if it has been done, but i was thinking it would be great if there was a linux distro based perhaps on debian, which is designed to be loaded onto an x86 machine (or virtualbox) which gives us an uptodate, clean build of a working cross compile too...

Bare Metal "Hello Framebuffer World"

Ok so this might be a complex hello world "assignment", but i was pondering how hard it would be to code a bare metal hello world (as kernel.img which is loaded by start.elf) in c, which then loads a hello.bmp (or hello.png, whichever is easier) and displays it as a static image, viewable on the hdm...

Re: Mixing 8 raspicam images in real time

i realise this is an old topic... but anyway how did your project work out? one thing i though of was to roll your own parallel data exchange (2x 8 = 16 bits wide) between the camera pi's and the processing pi - using the GPIO pins. you'd need to write a custom driver for it, but given it's specific...
