Support can be enabled for different varieties of ROM monitor.
|
| 309 |
|
|
This support changes various eCos semantics such as the encoding
|
| 310 |
|
|
of diagnostic output, or the overriding of hardware interrupt
|
| 311 |
|
|
vectors.
|
| 312 |
|
|
Firstly there is \"Generic\" support which prevents the HAL
|
| 313 |
|
|
from overriding the hardware vectors that it does not use, to
|
| 314 |
|
|
instead allow an installed ROM monitor to handle them. This is
|
| 315 |
|
|
the most basic support which is likely to be common to most
|
| 316 |
|
|
implementations of ROM monitor.
|
| 317 |
|
|
\"GDB_stubs\" provides support when GDB stubs are included in
|
| 318 |
|
|
the ROM monitor or boot ROM."
