CE 6.0 Kernel reboots early

[wy...@superspider.net]

I try to bring up the CEPC on a AMD Geode LX700 Platform, but the CE
Kernel seems to reboot early in the boot phase. Here is what Debugout
says:

<Windows CE 6.0 CEPC Debugout>
Debug Serial Init

I also have CE 5.0 and so I tried to do the same CEPC build in CE 5.0
on the same hardware with the same configuration. Interestingly, there
is no such problem with the CEPC build from CE 5.0. Here is the
Debugout:

...(continues)

I double checked the ce.bib and reginit.ini files to be sure that they
are the same in CE5.0 and CE6.0. I have also found some other threads
concerning the same problem, but no solution, e.g.
http://www.eggheadcafe.com/software/aspnet/31812788/i-cant-download-wce-60.aspx

Can someone please give me a hint why the CE 6.0 kernel just reboots?

with kind regards, Stefan Wyss

I'm having the same problem. Any advice would be appreciated.

Thanks!

Hi,

This is difficult to guess because i don't have any expierance with your
board, and don't have enough info.

Build a debug kernel (if you didn't do that already) and turn on some more
debug messages (eg OALLogSetZones() for enabling debug messages in the oal).
