kernel debugger and CE 5.0

I uncheck "Enable Kernel Debugger" (IMGNODEBUGGER=1) in Build Options,
and then run Sysgen. But after downloading the image, I still see "The
kernel Debugger is waiting to connect with target.".
Why is that? I use CEPC off the bat. By the way, KITL is enabled, and
it does not work either. From the serial output, it says,
"ERROR:OALKitlInit:KitlInit failed". I use RTL8139 for both
downloading and KITL by disabling VMINI. The whole project used to
works on CE .Net 4.2. Any help is appreciated.

There are two flags IMGNOKITL and IMGNODEBUGGER. Second only disable
debugger to be loaded on Windows CE start. KITL connection should still be
active (and depending on your sysgen settings it will bring you shell and
debugger output). I can't say why KITL initialization failed (put full
serial output in message, to give us context). If you build IMGNOKITL
image - message you see is normal (yes, it can be little confusing). If you
want to run standalone image you can set debug option in connections to none
to avoid this.

I think your primary problem is that you don't specify correctly KITL
device. Can you post full serial debug output?

Ok it looks familiar. There is problem with DHCP server on your network (I
expect you are running on network with DHCP server). Can you check network
trace - to see if there is DHCP renew request and there is correct replay
from server?

We find that some DHCP servers from security reasons require optional device
name in DHCP request.

After I use a static ip, KITL works. But how come CE .Net 4.2 works
with our DHCP server?

What DHCP server are you using? We've found that some servers make hardcoded
assumptions about the order of the options in the DHCP requests and the CE
DHCP client doesn't always put them in the order that the server assumes.
While CE is a bit unusual in this respect it's not in violation of the
specs. The server is.
