29 How to build and install the GDB module on the MBX board
30
31 Make GDB module
32 ~~~~~~~~~~~~~~~
33 Configure and build using the 'stubs_old_scheme' template for the MBX
34 target. These are the necessary CLI instructions. It can also be done
35 from the Configtool by selecting the appropriate templates.
36
37 % cd /tmp
38 % mkdir stubs
39 % cd stubs
40 % ecosconfig new mbx stubs_old_scheme
41 % ecosconfig tree
42 % make
43
44 This will install some files in ./install/bin:
45
46 cygmon.img: The built stubs image
47 cygmon.bin: The image converted to binary (suitable for burning to ROM)
48 cygmon.srec: The S-Record image (suitable for flash programming, see below)
49
50
51 Prepare board for flash programming
52 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
53 This assumes you have EPPC-Bug in the on-board flash. This can be determined
54 by setting up the board according to the below instructions and powering
55 up the board. The EPPC-Bug prompt should appear on the SMC1 connector at
56 9600 baud, 8N1.
57
58 1. Set jumper 3 to 2-3 [allow XU2 flash to be programmed]
59 2. Set jumper 4 to 2-3 [boot EPPC-Bug]
60
61
62 Program FLASH
63 ~~~~~~~~~~~~~
64 1. Prepare EPPC-Bug for download:
65
66 EPPC-Bug>lo 0
67
68 At this point the monitor is ready for input. It will not return the
69 prompt until the file has been downloaded.
70
71 2. Use the terminal emulator's ASCII download feature (or a simple clipboard
72 copy/paste operation) to download the gdb_module.srec data.
73
74 Note: On Linux, Minicom's ASCII download feature seems to be broken.
75 A workaround is to load the file into emacs (or another editor)
76 and copy the full contents to the clipboard. Then press the
77 mouse paste-button (usually middle) over the Minicom window.
78
79 3. Program the flash with the downloaded data:
80
81 EPPC-Bug>pflash 40000 60000 fc000000
82
83 4. Switch off the power, and change jumper 4 to 1-2. Turn on the power
84 again. The board should now boot using the newly programmed stubs.
