Support can be enabled for different varieties of ROM monitor.
|
| 380 |
|
|
This support changes various eCos semantics such as the encoding
|
| 381 |
|
|
of diagnostic output, or the overriding of hardware interrupt
|
| 382 |
|
|
vectors.
|
| 383 |
|
|
Firstly there is \"Generic\" support which prevents the HAL
|
| 384 |
|
|
from overriding the hardware vectors that it does not use, to
|
| 385 |
|
|
instead allow an installed ROM monitor to handle them. This is
|
| 386 |
|
|
the most basic support which is likely to be common to most
|
| 387 |
|
|
implementations of ROM monitor.
|
| 388 |
|
|
\"GDB_stubs\" provides support when GDB stubs are included in

| 389 |
|
|
the ROM monitor or boot ROM."
