Hi
I’ve been using neutrino 2.0 (developing under codewarrior on win95) for a
while now running on my target machine which is a PC/104 486 card with an
8meg DOC. I’ve used fdisk and dinit for partitioning and creating a qnx4
file system and copied my boot image to /doc/.boot
Fine - all worked fine and dandy.
I’ve now changed my development platform to RTP and tweaked my image
buildfile accordingly. I can run the diskonchip driver fine, fdisk ( set
loader and boot etc), dinit etc - I’ve even got qnet running for
transferring all my files over to the mounted filesystem.
One problem - i’ve got my new image file copied over to doc/.boot , power
cycle the board and… nothing
It looks like the bootloader is failing somewhere - I get a BIOS message
‘Booting Operating System…’ and a flashing cursor and thats it. I know the
boot image is ok as it boots from it when on floppy. I don’t even get the
‘Press Esc for alternate OS…’ message so its getting stuck b4 that.
Is there something I’m missing, has there been a major change in fdisk
between Neutrino2.0 and RTP? Its the only thing I can think of really thats
different.
Any clues anyone?
Regards
Jim
Whats the size of the boot image?

Basically the situation now is that I’ve used one of my old neutrino 2.0
boot images (on floppy) which just has fdisk/dinit on and i’ve run both of
these on the device so that i have an empty qnx4 filesystem as built by
neutrino 2.0.
I’ve then used my boot image created on RTP to get qnet running and copied
all the required libraries/binaries to the mounted filesystem on the
diskonchip. Finally copied the RTP created boot image to /diskonchip/.boot
and it boots.
Looks like something fishy between neutrino 2.0 and RTP versions of
fdisk/dinit maybe??
600568 - I don’t think its a memory problem - i dont think its getting as
far as trying to boot from my image…

Just wanted to check the obvious things first, can you bring a Qnx 4.25 session up and do the dinit/format thing there?
