Hello All,

I am trying to load a boot image from a Compact Flash. The system booted earlier, but i made some changes to the build file…now it gives me
Hit Esc for .altboot …
and then hangs. I tried pressing different keys on the keyboard…esc , spacebar nothing works.

I also tried running my old image file which used to work…but still gives the same error.

Please help with some suggestions to fix it.

Thanks.

Hi Neelay,

I had same problem to boot my image file. It was posted in couple of days before in yyang2000. Could you please post your script build file here to let me get a sample. Also, a quick question why do you use type 79 instead of type 77? What is different between type 77, type 78 and type79?
I was using the same command as you did to load image to /dev/hd1t77, but not successfully. Maybe I have to try type 79.

Thanks,

Hi Yang,

I am posting my build file…you can modify it accordingly …based on your needs.

I am using type 79 because thats where my bootable image is loaded. When you do
fdisk /dev/hd1
It gives you a GUI, so there I have set my boot sector to be 79.

Hope this helps.

Cheat and make the /temp point to the shared memory area…

[type=link] /tmp=/dev/shmem

Programs require the runtime linker (ldqnx.so) to be at a fixed location

[type=link] /usr/lib/ldqnx.so.2=/proc/boot/libc.so

We use the “c” shared lib (which also contains the runtime linker)

#libc.so
libcpp.so.2a
libm.so.2
libc.so.2

#For PED
#libAp.so.2
#libph.so.2
#libphrender.so.2
#libgri.so.2

Include the socket library

libsocket.so
libsocket.so.2

Just incase someone needs floating point…

fpemu.so.2

Include filesystem libs

libcam.so.2
cam-disk.so
cam-cdrom.so
io-blk.so
fs-qnx4.so
fs-cd.so

Include the network files so we can access files across the net

devn-rtl.so
npm-ttcpip.so

The files above this line can be shared by mutiple processes

[data=c]

Executables must currently be below this line

Include a console driver

devc-con

Include the network executables.
