Booting without diskboot

QNX Newsgroups (Archives) qdn.public.qnxrtp.installation

I have built several customized OS ‘with’ diskboot and I have been able to
add features the way I want it. I understand all of mkifs and most if the
individual drivers.

But, . . .

I wanted to build an OS without diskboot. I wanted to load the drivers
myself. I know what they should look like (I think). But I can’t seem to
get it to work.

I have looked into /boot/build and have read through all of the other build
source files and I can’t get any of them with diskboot to work unmodified.

When I try to build a version without diskboot the system wait for about 1
minute and then I get a bunch of “not found” messages.

What is the magic that I am missing if I don’t include diskboot?

About a “for instance” :^)

Hi Bill,

A good explination can be found here:

http://qdn.qnx.com/articles/oct1901/Using_buildfiles.html

or in the Building Embedded systems manual.

Take care!

Hello Bill

Here is my boot file for my PC, it doesn’t use diskboot. This was
takeng from Chris’s page I thing. I needed to get rid of disk boot to
control devb-eide’s cache.

This sets up the kernel and proc.

- x86 based kernel using the bios.boot to set things up.

- Compression is turned on.

- Use startup-bios to finish setting up the machine.

- Start procnto after startup-bios is finished.

[virtual=x86,bios +compress] boot = {
startup-bios -v
PATH=/proc/boot:/bin:/usr/bin:/sbin:/usr/sbin
LD_LIBRARY_PATH=/proc/boot:/lib:/lib/dll:/usr/lib:/usr/photon/dll procnto -v
}

Once procnto is running it will mount the image filesystem and

run this script.

Thanks Mario

Seeing that helps and explains a few things. BUt I’m still having a
problem. When it tries to enumerate devices it is failing to load io-audio
and io-net. Also, I can not run photon after it boots. All because of
missing shared libraries.

I know that all of these things are loaded from diskboot in the boot script.
But without diskboot they are loaded from /etc/system/sysinit which calls
/etc/rc.d/rc.devices. At the beginning of /etc/system/sysinit I added a
line to print LD_LIBRARY_PATH and it is empty. When/where/how should
LD_LIBRARY_PATH be populated when calling /etc/system/sysinit?

Here is a dump of the errors on my screen (hand copied so there may be
typos).

There is a single line above. It should populate PATH and LD_LIBRARY_PATH for every spawned
proccess.

I have this in my boot script but not in my startup script. DO I need in
the startup script too?

Also, I see you say that it must be a single line. That may be my problem.

Apparently I don’t need this in the start up script. In the boot script
these were NOT on a single line. Putting them on a single line solved my
problem,

QUESTION 1:
When I boot the default qnxbasedma image it loads enum-devices, enum-pccard
and spooler. Or at least they are still resident when I do a ‘pidin ar’.
But they are not found in this custom boot image. Who/what/when do they get
loaded in qnxbasedma?

QUESTIONS2:
Why doesn’t pidin support the ‘-P progname’ like sin did? You MUST add
that.

Bill,

There are couple of finest articles at QDN web site, please visit
http://qdn.qnx.com/articles/oct1901/Using_buildfiles.html
http://qdn.qnx.com/articles/oct1901/Using_buildfiles2.html

QUESTION 1:
When I boot the default qnxbasedma image it loads enum-devices, enum-pccard
and spooler. Or at least they are still resident when I do a ‘pidin ar’.
But they are not found in this custom boot image. Who/what/when do they get
loaded in qnxbasedma?

I guess enum-* and spooler are loaded by sysinit (by its child scripts) in either ways (custom or
standard image). I’m not sure enum-* are still resident in my system when I boot the default
qnxbasedma image. I’ll check it out. But it seems very strange for me because I don’t think QNX RTP
supports “hot” device reconfiguration by enum-devices daemon at least.

QUESTIONS2:
Why doesn’t pidin support the ‘-P progname’ like sin did? You MUST add
that.

I hope anybody from QSSL will answer this question

Bests

Pipe provides pipe() services.

display_msg “Starting pipe manager…”
pipe &
waitfor /dev/pipe

Pipe manager is started by sysinit under normal circumstances (standard image). What is reason to
start pipe here?

Start eide driver to get drive access.

[cut]

Diskboot seems to enumerate unmounted partitions under /dev and to mount them to /fs. I have
removable eide hdd in system and it is a great feature for me :wink:. Standard image allways finds
knowen partitions on removable hdd and mounts them (and CD-ROM also). Has anybody experience with
writting such script?

These are the standard, required links

[type=link] /dev/console=/dev/con1
[type=link] /usr/lib/ldqnx.so.1=/proc/boot/libc.so

Is it required link in QNXRTP6.1A? I mean ldqnx.so.1

Thank you in advance,
Eduard.
