Hi I have a Sandpoint X3 main board with an Altimus 7410 processor
installed.
When I build a QNX image for this board and download it the system hangs
with no output whatsoever. After modifying the startup-sandpoint main.c
file to remove the following:
reference to “CALLOUT_SLOT ( reboot, _sandpoint)”,
Turning off Ibat and Dbat translation,
call to “ppc600_init_caches()”
The board will boot fine, and I appear to have a working system with
serial channels and PCI control.
There is a cryptic reference to the 7410 in the documentation that
suggests that the only way to boot this board is by burning the IPL/OS
image onto the boot flash, but I cannot find an explanation as to why?
I believe that this may be a problem with the configuration of the rom
monitor (DINK32 V12.3) but so far I’m stumped.
Any Suggestions?

In what doc did you find this reference? In any case you should be
able to boot the 7410 without modifying startup. The later versions of
DINK32 (12.1 >) turn on the caches. This causes us problems; simply
typing “rm hid0” followed by zero will alleviate the problem. Make sure
you do this before downloading the image.
The OS will take care of re-enabling the caches.

Yep, you’re correct.

Thanks, That fixed it!
The cryptic message is in /bsp_en/sandpoint/install (under help) and
it says :
You cannot use DINK32 to boot the 7410 or 7450 board, you’ll
have to burn the image into the flash using an EPROM burner…
Cheers

Ok, I’ll check into it. The info from the previous post (rm hid0)
is part of the next release.
