|
|
* STARTUP_FROM_RESET
|
| 16 |
|
|
*
|
| 17 |
|
|
* If defined, the program will startup from power-on/reset. If not defined
|
| 18 |
|
|
* the program will just loop endlessly from power-on/reset.
|
| 19 |
|
|
*
|
| 20 |
|
|
* This definition is not defined by default on this target because the
|
| 21 |
|
|
* debugger is unable to reset this target and maintain control of it over the
|
| 22 |
|
|
* JTAG interface. The advantage of doing this is that it allows the debugger
|
| 23 |
|
|
* to reset the CPU and run programs from a known reset CPU state on each run.
|
| 24 |
|
|
* It also acts as a safety net if you accidently download a program in FLASH
|
| 25 |
|
|
* that crashes and prevents the debugger from taking control over JTAG
|
| 26 |
|
|
* rendering the target unusable over JTAG. The obvious disadvantage of doing
|
| 27 |
|
|
* this is that your application will not startup without the debugger.
|
| 28 |
|
|
*
|
| 29 |
|
|
* We advise that on this target you keep STARTUP_FROM_RESET undefined whilst
|
| 30 |
|
|
* you are developing and only define STARTUP_FROM_RESET when development is
|
| 31 |
|
|
* complete.
