I have made it work after 2 years ... QNX BSP Support is added to Raspberry (bcm2835)... I made it open source ... Hack: Raspberry Pi(BCM2835) QNX 6.5 Sp1 Source code

I thought at first it might be simply an advert, but some digging found this. http://swhwc.com/bussiness/products.html?lang=en Mark

yes there are restriction on distributing the final qnx image ( it used to be 150$ per system run time license , now they might have reduced it ) , but no restriction on giving the BSP source code .. Its free and apache license .. I have updated the source code link.. (Need QNX 6.5 IDE to compile )

There is a company that has done a port of QNX to Raspberry... http://swhwc.com/?lang=en

After some research I found , It is possible to Make QNX porting for Raspberry PI .. The documents available in the public domain are more than sufficient .. I have got a hobbyist license for QNX6.5.0 . My attention got diverted towards WinCE( Got dreamspark licence for wince 7) ,as there is a partial porting already available & I got extensive experience on Windows based systems . https://ceonpi.codeplex.com/ . dboling did a wonderful job.. He has finished the kernel startup/serial & graphics support.. He got struck with USB ... I tested it using Rasperry B+ module, its working well .. Since there is No usb support ,we cant feed any input to the OS.. So I added some application in the startup OS routine to turn ON LEDs , It is working well .. I am adding the USB support , just half way through ... once it is done ,i will put the code in Github.. For those who are interested.. here is the method .. we can add usb driver support in 2 ways .. 1. USB bare metal code is available here https://github.com/Chadderz121/csud By exploiting the USB stack , we can just get the mouse & keypad data and using that data we can simulate the window events (mouse movements /key press)... Kind of PS/2 keyboard mouse , but still it will use USB port. I know , it is a bad way of coding , but the advantage is, time will be greatly saved ... No coding required 2.Other method is tinkering the (ochi/echi/uhci/) code & making it work with Designware stack .. It is the best method , because once usb stack is UP , keypad ,mouse ,touch , pen drive ,LAN everything will work automatically .. Parallely I am going to work on QNX too ..

It's a link external to the website I suggest you make contact with the owner of that site. Electronics / Embedded / Firmware /Software /Hacking Mark

On the site intro they wrote: This is a very primitive BSP presently but capability can be expanded (to some degree) per user needs. Due to the lack of hardware manual from Broadcom, I heard no one wanted to develop QNX BSP for Raspberry Pi. Our Vietnamese engineer friends have gone through incredibly hard development without any hardware manual. They had to reverse engineer hardware spec from reference code. Now Broadcom and Avago merged we will see what happens to the documentation situation. Noticeable the reverse engineering of their guy but if by one side there is no hardware info by the other there is - at least, but I think can be found more - a whole bunch of different linux versions running on the PI. Why not to take a look on how these distro works, plus the sources (opensource) libraries to manage the various hardware features, GPIO and so on instead of risking to become crazy with a hardware exploitation ? It's just a doubt. Enrico
