porting QNX

Hi all,
    we are trying to port QNX on mpc85xx board. we downloaded the BSP 
file and got the image (ifs-cds8555.raw).
we downloaded this image  onto RAM location(0x100000) using tftp and 
when we try to boot it, the system gets hanged.
Can anyone suggest me any idea to solve the problem.
Thank U

Re: porting QNX

Hi, V.Murugadoss.

I'm trying to port QNX on my own board as well.

Though I don't completing the work, I'd like to tell you somthing helpful.
I met almost errors and mistakes at several callouts e.g. interrupt and timer.  As for me, because of unfamiliar 
assembly code, there would be errors in these region.

Best regards.

Pusik.

Cf. I attach the file downloaded from qnx.com about QNX startup.  This presentation is useful.

Re: porting QNX

Hi Pusik Park,
    Thank you for the resource. Pl clarify one more doubt. In my bsp 
file in ../src/.../startup location, i don't have IPL folder/file as 
specified by the qnx documents. As this is initial program which takes 
the control from u-boot. Do this affect the process r this may be the 
problem. Give me some suggestions.
Thank u

Re: porting QNX

Hi,

You don't need an IPL when you have U-Boot. The IPL can be seen as a ligthweight version of UBoot that will only make 
minimal board initialization to allow us to boot a QNX image.

In your case I will first start looking at the memory layout of your system. This is normally one of the first issue you
 might have. Then I'll check my serial interface to determine if it is similar to (same controller and pinout) the 
reference BSP I'm using. 

One trick we are using he is to write dirrectly to the TX data register of the serial driver at the entry of main 
function in your startup. Since U-Boot already initialize the serial interface you should be able to send a character 
without writing any code. This way you'll know for sure if you reach the main function of the startup lib.


Cheers,

Nicolas
