How to debug bootloader using ARM eXDI driver for Windows CE PB?

From the help of Windows CE Platform Builder 4.2 I knew that bootloader can
be debugged by eXDI hardware driver and then I downloaded the ARM eXDI driver
for Windows CE PB from www.arm.com. But the help of Windows CE Platform
Builder 4.2 don't detail how to debug bootloader using eXDI driver. Who can
tell me what I should do to debug bootloader of WinCE? The target board is
S3C2410. Thanks.

First you'll need to check that your ICE is correctly setup to recognise the
CPU.

Next, once ICE connection is ok, and ExDI driver installed, you can setup in
PB connection settings the fact that PB should use ExDI to debug. Then, open
nk.bin file with PB to start JTAG debugging

Hello,Yannick Chamming's
Thanks for your answer. And I have two questions related to this topic to
ask you. If I use eXDI to debug eboot.bin, how can I open it with PB? The
other question is it is printed by the help of WinCE PB 4.2 that breakpoint
in flash ROM can be set by eXDI but not detailed much. Can you tell me how to
set breakpoint in flash ROM? Thanks a lot.

Just drag and drop eboot.bin to a pb window. Pb will open the .bin file.
Then, configure target connection to use ExDI and launch debugger (F5 key).

PB will automatically connect to the target through JTAG, and will break at
the current instruction. Then you can debug as usual.

Setting breakpoint in flash ROM can be done the same way as in SDRAM : you
set a breakpoint at a specific line of source code. The important point is
that even if the code at this place is executed in ROM, using ICE debugger
will allow you breaking at this line of code, which is not the case without
ICE/JTAG debugging

You will also want to rename the eboot.exe / eboot.pdb to nk.exe / nk.pdb
respectively.

When setting breakpoints in flash ROM, you will want to use a hardware
breakpoint. Using the breakpoint dialog, you can specify whether to set a
hardware / software / any breakpoint. Most probes support both hardware
and software breakpoints, and in the general case, the number of hardware
breakpoints are limited when compared to the number of software breakpoints
availabe. Hardware breakpoints typically use a cpu debug register or
internal debug functionality exposed through JTAG. Software breakpoints
involve writing a trap instruction recognizable by the probe in memory,
which will obviously fail when debugging ROM.
