Not sure why this wasn't installed on your hosts but you probably need 
the SP1 libc.so (see attached).

Something must have gone wrong with your build of the new image(didn't use the 650SP1 installed bins/libs)....what is 
the output from running mkifs with -vvvv option.

Also, what is the output from the following on your 2 machines?
ls -l /.boot

Subject: 6.5.0SP1 devc-ser8250 error

I installed 6.5.0 SP1 on my target machine, and my windows development machine, and built an updated boot file. When I 
attempt to load my boot file, I get the following error:

ldd:FATAL: Unresolved symbol "hwi_find_item" called from Executable

I saw topc22117 and collected the information below. As far as I know, this is not a pre-release version of SP1; I 
pulled qnxsdp-6.5.0SP1-201206270843-nto.sh and qnxsdp-6.5.0SP1-201206261830-win32.exe from qnx.com on August 6th.

As was the case in topc22117, it looks like the binaries are 'old'. Why is that? Is there more required to install SP1 
than running the .exe on my development machine and the .sh on my target? Thanks.

Hmm, when I ran mkifs with -vvvv, everything look OK (see below). I tried the 'quad-v' image on the system and the error
 was gone. I'm at a loss to explain the difference between the two mkifs runs. Thanks for the help.

Here's output from mkifis.

I encoutered the situation too. But I solved the issue successfully.
Please using "mkifs" to make a new image under SP1 enviroment, and please using new image to cover the old version "/.
boot", then reboot again. You can't see this message again.
