What do you mean by this? Can you post the build file? What version
of QNX 4 are you using.

Can I mage Dev at 32 on my sysinit?

If you built an image with Proc (the 16-bit process manager & kernel),
then you can’t run any 32-bit process (which require Proc32).

If you mean that you ran several 16-bit drivers (e.g. Dev16, Dev16.ser)
in your image, but also used Proc32, then you may be able to do something.

How gan I do?

You can run 32-bit Dev in sysinit with a different prefix:

e.g.

Dev32 -N /dev32 &
Dev32.ser -N/dev32/ser &

If you don’t want both running, you may be able to kill the 16-bit ones
in your sysinit, then start the 32-bit ones. I’ve not tried this, so
don’t know if there are any dependencies/problems that would come of
trying it. Better would be to build a boot image with the 32-bit
ones.

thanks for your answer…
I have 4.25 and my image is at 16 bit.
I tried to do with that you suggest to my, but my parallel still don’t
work.
have you any trouble to tell my.

Without knowing what you actually did, no I can’t tell you what
went wrong.

Can you post your buildfile and the sysinit that you tried to use,
and tell me what errors you got, or what seemed to go wrong?

Without that information, I can’t even begin to have any idea as
to what might be going wrong.
