How to build and install the GDB module on the MBX board
Make GDB module
~~~~~~~~~~~~~~~
Configure and build using the 'stubs_old_scheme' template for the MBX
target. These are the necessary CLI instructions. It can also be done
from the Configtool by selecting the appropriate templates.
% cd /tmp
% mkdir stubs
% cd stubs
% ecosconfig new mbx stubs_old_scheme
% ecosconfig tree
% make
This will install some files in ./install/bin:
cygmon.img: The built stubs image
cygmon.bin: The image converted to binary (suitable for burning to ROM)
cygmon.srec: The S-Record image (suitable for flash programming, see below)
Prepare board for flash programming
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This assumes you have EPPC-Bug in the on-board flash. This can be determined
by setting up the board according to the below instructions and powering
up the board. The EPPC-Bug prompt should appear on the SMC1 connector at
9600 baud, 8N1.
1. Set jumper 3 to 2-3 [allow XU2 flash to be programmed]
2. Set jumper 4 to 2-3 [boot EPPC-Bug]
Program FLASH
~~~~~~~~~~~~~
1. Prepare EPPC-Bug for download:
EPPC-Bug>lo 0
At this point the monitor is ready for input. It will not return the
prompt until the file has been downloaded.
2. Use the terminal emulator's ASCII download feature (or a simple clipboard
copy/paste operation) to download the gdb_module.srec data.
Note: On Linux, Minicom's ASCII download feature seems to be broken.
A workaround is to load the file into emacs (or another editor)
and copy the full contents to the clipboard. Then press the
mouse paste-button (usually middle) over the Minicom window.
3. Program the flash with the downloaded data:
EPPC-Bug>pflash 40000 60000 fc000000
4. Switch off the power, and change jumper 4 to 1-2. Turn on the power
again. The board should now boot using the newly programmed stubs.
