/* alt_log_printf.h

|
|
*
|
| 3 |
|
|
* ALT_LOG is designed to provide extra logging/debugging messages from HAL
|
| 4 |
|
|
* through a different port than stdout. It is enabled by the ALT_LOG_ENABLE
|
| 5 |
|
|
* define, which needs to supplied at compile time. When logging is turned off,
|
| 6 |
|
|
* code size is unaffected. Thus, this should be transparent to the user
|
| 7 |
|
|
* when it is not actively turned on, and should not affect projects in any way.
|
| 8 |
|
|
*
|
| 9 |
|
|
* There are macros sprinkled within different components, such as the jtag uart
|
| 10 |
|
|
* and timer, in the HAL code. They are always named ALT_LOG_<name>, and can be
|
| 11 |
|
|
* safely ignored if ALT_LOG is turned off.
|
| 12 |
|
|
*
|
| 13 |
|
|
* To turn on ALT_LOG, ALT_LOG_ENABLE must be defined, and ALT_LOG_PORT_TYPE and
|
| 14 |
|
|
* ALT_LOG_PORT_BASE must be set in system.h. This is done through editing
|
| 15 |
|
|
* <project>.ptf, by editing the alt_log_port_type & alt_log_port_base settings.
|
| 16 |
|
|
* See the documentation html file for examples.
|
| 17 |
|
|
*
|
| 18 |
|
|
* When it is turned on, it will output extra HAL messages to a port specified
|
| 19 |
|
|
* in system.h. This can be a UART or JTAG UART port. By default it will
|
| 20 |
|
|
* output boot messages, detailing every step of the boot process.
|
| 21 |
|
|
*
|
| 22 |
|
|
* Extra logging is designed to be enabled by flags, which are defined in
|
| 23 |
|
|
* alt_log_printf.c. The default value is that all flags are off, so only the
|
| 24 |
|
|
* boot up logging messages show up. ALT_LOG_FLAGS can be set to enable certain
|
| 25 |
|
|
* groupings of flags, and that grouping is done in this file. Each flag can
|
| 26 |
|
|
* also be overridden with a -D at compile time.
|
| 27 |
|
|
*
|
| 28 |
|
|
* This header file includes the necessary prototypes for using the alt_log
|
| 29 |
|
|
* functions. It also contains all the macros that are used to remove the code
|
| 30 |
|
|
* from alt log is turned off. Also, the macros in other HAL files are defined
|
| 31 |
|
|
* here at the bottom. These macros all call some C function that is in
|
| 32 |
|
|
* alt_log_printf.c.
|
| 33 |
|
|
*
|
| 34 |
|
|
* The logging has functions for printing in C (ALT_LOG_PRINTF) and in assembly
|
| 35 |
|
|
* (ALT_LOG_PUTS). This was needed because the assembly printing occurs before
|
| 36 |
|
|
* the device is initialized. The assembly function corrupts register R4-R7,
|
| 37 |
|
|
* which are not used in the normal boot process. For this reason, do not call
|
| 38 |
|
|
* the assembly function in C.
