Warm boot / fails to re-initialize system

Hi
I have an Aaeon PCM8152 / Celeron M running standard CEPC winCe5.0.
When I warm reset the system, or switch is off/on within a few
seconds, I get this error.
The bootloader runs fine, but afterwards the first part of kernelinit
fails =96 the system never recovers.
Leaving the system for 30 sec. it alwayes powers correct up.

As I can understand this problem is not isolated to my target. The
most interesting solution I have managed to find is implementing a
call to NKForceCleanReboot in OEMInit().
Questions:
NKForceCleanReboot is not declared in any of my header files. Am I
suppose to implement it myself?

Using the CEPC standard BSP I=B4m not sure which file my OEMInit() is
located?

Perhaps someone have done a similar fix up of OEMInit() and can show
how?

Any other suggestions or comments?

Best regards,

Did you look up NKForceCleanBoot in help, or anywhere else?

For CEPC, your OEMInit is in Platform\Common. You will need to copy it to
your BSP and then modify it.

Keep in mind that without handling a reset of the PCI bus specific to your
motherboard, which requires you to write some BSP-specific code, you may run
into problems with warm reset.

NKForceCleanBoot (not NKForceCleanReboot) is implemented in the kernel, and
the header public\common\oak\inc\pkfuncs.h contains the function
declaration.

OEMInit can be found here:
macallan\platform\common\src\x86\common\startup\oeminit.c.

[SNIP]

Implementing call to NKForceCleanBoot() in the last part of OEMInit()
did the trick - the startup is now rock solid.
Thanks!
