Have you worked on topic QNX6.5 for raspberry pi 3(BCM 2837)? I want to install it on BCM2837...will you please help me out?

There is a project I want to work on with QNX on the Raspberry Pi 3. So, I would very much like to see this happen!!

all features of BBB is working fine .. on Raspberry 3 ,hopefully I will get a board by Oct end , Mean while you can copy the content https://github.com/varghes/Raspberry-QNX/tree/master/working_image

to sd card & boot that with raspberry 3 & let me know what error it displays /stucks. I am working on MMC & USB part , may be you can help me on that

Hello,

I am interested in doing work for BBB or Raspberry pi 3 for porting QNX to these targets.

Do you need any help?

Thank you.

Well, at present I am in the process of adding mmc & USB support to BCM2835 , if any one wants Raspberry 2 & 3 (BCM2836/BCM2837) urgently, then they should donate me that board . at present we have fully working beaglebone black (including HDMI video /USB ) + QT apps

Memory map is same , so Single core might run ... I have not tested it on rpi 2/3 ...

To run other cores , we need to turn on SMP , which is not yet implemented ..

AFAIK the PI3 architecture I think there is not a structural difference creating some impeachment that we will expect it can't work. But the best choice is to try.

Hello,

Will it work also on Raspberry Pi 3 Model B?

if not, how much time would it take to port it?

Thank you.

Could you help to introduce how to create an academic license?

Is the progress very complicated?

RE: Raspberry PI - QNX

varghese_a — Sun, 12 Mar 2017 18:04:40 GMT

the link is down ...

I have pushed it to the github ..

https://github.com/varghes/Raspberry-QNX

Source code is free/opensource , but any commercial distribution of final qnx image requires run time license from QNX..

I have kept the final image for testing / academic use.. as this board is normally used for hobbyist..

Thanks for your response will check with owner of the site.

Type QNX into the search at the top left and you'll find several references

It's a link external to the website

I suggest you make contact with the owner of that site.

Hi,

I am working on porting QNX on raspberry pi board. Browsing through internet found this page. I tried downloading the BSP source from this link.

https://www.element14.com/community/external-link.jspa?url=http%3A%2F%2Fihaack.blogspot.in%2F2016%2F12%2Fraspberry-pibcm…

The link appears broken. Can somebody provide the correct link. This would help in speeding up the board bringup activity.

Regards

Anant

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 )

Congratulations ! You are one persistent person. I checked out your link and like I said previously I would really like to experiment with

this but I just can't afford or get around the license requirement. I see that that has (not surprisingly) prevented you from publishing an

image also. Oh well.

I have made it work after 2 years ...

QNX BSP Support is added to Raspberry (bcm2835)... I made it open source ...

Great, I thought so! I would love to experiment with QNX but needing a license gets in the way. If the source is available you might want to take a look at the Linux USB driver

as it has been highly tuned to get decent full USB host performance out of the USB OTG hardware.

I have considered porting a couple of Linux kernel real-time patch sets such as RTAI (Real Time Application Interface) or Xenomai but they tend to be well behind kernel

development so finding a recent kernel compatible version is a problem and I just can't find time to do it. I still haven't heard much of anything good about the official Linux

kernel real time patches.

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 ..

I'm not sure why they say there is no hardware manual as there has been one out for all the SoC peripherals (except USB) for a couple of years now and one for the GPU for at least a year now.

In past I have rebuilt a Ubuntu linux OS inside a Android box with full system replacement (Android dismissed) and to be honest, never opened this stuff , then refactored a tablet with Ubuntu swappable with Android and never opened it

Well spotted.

I just went to see if it was there. I have no use for it but the original OP might ...

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.

I thought at first it might be simply an advert, but some digging found this.
