Hello,

The problem in a nutshell is that the Kernel Debugger in PB 5.0
immediately disconnects after each serial connection attempt to our x86
derivitive device (which does not have an NE2000 compatable ethernet
chipset):

"The Kernel Debugger is waiting to connect with target.
The Kernel Debugger has been disconnected successfully."

First of all, the PB target device connectivity options are set as
following:

Serial download and transport set to 115200/8/n/n/1 on COM 2 (I've
tried hardware handshaking as well to no avail)

I rang the cable out, it excatly matches the NULL modem cable
architecture as given in the PB help. This cable is known to have
worked with ActiveSync.

The debug text coming out of sboot.bin (via COM1 on the device):
"Sending boot request...
Waiting for boot ack...
failed to receive header signature
failed to receive header"

If use a terminal program to look at the data coming into COM2 on the
PC (out of COM2 on the device), at 115200/8/n/n/1, it looks like:
"kITL=BB$CEPC"

This seems like a problem in my installation of PB, where it's just not
responding to the request from the device. I've done plenty of
searching in this group, but to no avail. Any thoughts?

Thank you,=20

Well, no response so far. I ended up getting very lucky; Intel produced
a BSP for the 815 chipset, with an attendent variety of ethernet
bootloader which worked after a little modification. Since I am able to
use an ethernet/kitl connection, serial debugging on this device is no
longer an issue.

Thanks anyway,
