Build the examples
The examples are ported on several boards. You can select the board on the command line with make or by changing the board.def file.
The following boards are supported:
| m68hc11-32k | 68HC11 generic board with 32K ram and 32K rom
| Data | 0x1040..0x7fff |
| Stack | 0x7fff |
| Text | 0x8000..0xffff |
Prefer this board if you want to use the simulator.
|
| m68hc11-cme11 | Axiom Manufacturing CME11 board with Buffalo monitor
| Data | 0x1040..0x1fff |
| Stack | 0x1fff |
| Text | 0x2000..0x7fff |
|
| bootstrap | 68HC11 bootstrap mode
| Data | 0 |
| Stack | 0x0ff |
| Text | 0x00..0x0ff |
|
| eeprom-512 | 68HC11 512 eeprom mode
| Data | 0 |
| Stack | 0x0ff |
| Text | 0xB600..0xB7FF |
|
| m68hc11-ebcs
| 68HC11 board with 8K ram (SCz board)
| Data | 0xE000..0xE1ff |
| Stack | 0x0ff |
| Text | 0xE200..0xFfff |
|
| m68hc11-6270
| MIT 6.270 68HC11 board
| Data | 0xE000..0xE1ff |
| Stack | 0xFFBF |
| Text | 0x8000..0xDfff |
|
| m68hc12-axcmd12 | Axiom Manufacturing CMD12 board with DBug monitor
| Data | 0x2000..0x2fff |
| Stack | 0x3000 |
| Text | 0x3000..0x8000 |
|
The board is configured either by specifying it to the command line or by updating the file config/board.def. For the first method, type the following command:
make TARGET_BOARD=board-name
where board-name is the name of the board picked from the table above.
Otherwise, in config/board.def change the line:
TARGET_BOARD=
to put the board you selected.
Before launching make you should make sure the GNU Binutils and Gcc executables are in your path. Then, proceed with the following commands:
make
or
make TARGET_BOARD=board-name
This will build the examples in all the sub-directories.
To execute the program, .... you have some choice:
| Simulator | m6811-elf-run <prog>.elf
or
m6811-elf-run -v <prog>.elf |
| Gdb Sim | m6811-elf-gdb <prog>.elf
(gdb) target sim
(gdb) load <prog>.elf
(gdb) run
|
| Gdb Buffalo | m6811-elf-gdb <prog>.elf
(CME11) (gdb) set remotebaud 9600
(gdb) target buffalo /dev/ttyS2
(gdb) load <prog>.elf
(gdb) run
|
| Gdb Dbug | m6811-elf-gdb <prog>.elf
(CMD12) (gdb) set remotebaud 9600
(gdb) target dbug /dev/ttyS2
(gdb) load <prog>.elf
(gdb) run
|
| Bootstrap | Upload the program (either <prog>.elf, or <prog>.s19) with your favorite target manager. |
| Prom | Burn the <prog>.b in some prom. |
