I’am testing bootp at the moment. When the client starts to download the
image it stops and tells me the file is not a valid image. Could someone
post a minimal .bld file that works with bootp or tell me if there is
something else I do wrong?
Thanks!
I guess the problem is that bootp expects the boot image to be either in TAGGED or ELF or a.out formats. The QNX mkifs utility creates a boot image that originally doesn’t correspond to any of them. To make your image compatible with bootp you have to wrap it properly. There are 2 ways to do it. The first one is to use proper filter inside of build file, but unfortunately I haven’t figured out how to do it. The second approach is to apply a filter after you create a boot image. For example, for x86 you do:
mkifsf_elf 3 0x3d0 image.ifs
Where 3 is ELF machine type for x86, the 0x3d0 is your boot image startup offset. To find the offset type dumpifs image.ifs and have a look at Startup-header line.
You have to apply the filter every time you rebuild your image.
I was told that in 6.2.1 all this can be done by mkifs.
Sincerely,
Serge

It works perfectly now using mkifsf_elf 
. Thanks again. I have received
my Qnx 6.2.1 upgrade today so I’ll test if it is able to tag the image
itself…

Note you can set this automatically by changing the virtual=x86,bios

Does mkifsf_elf on 6.2.1 do the “right thing”?

I’m not aware of any changes to mkifsf_elf that would affect things like
this. What wasn’t working?

mkifsf_elf in 6.1.0 didn’t have enough IPL things to
boot ex. over-16MB-memory machines.

Sorry, I was wrong - apparently it was fixed…
