|
||||
Now, I'm developing something like SYS for Kinetis L MCU, so, I write
|
||||
this document.
|
||||
|
||||
* Compatibility
|
||||
|
||||
SYS 1.0: The first verson
|
||||
SYS 2.0: Added clock_init, gpio_init
|
||||
SYS 2.1: Added sys_board_id, sys_board_name
|
||||
SYS 3.0: Don't setup NVIC priority by usb_lld_sys_init
|
||||
|
||||
|
||||
* Macro definition by DEFS in Makefile
|
||||
|
||||
- USE_SYS_CLOCK_GPIO_SETTING
|
||||
|
||||
Define this macro to ask chopstx/entry.c (the runtime code before
|
||||
MAIN function) to use function entries in SYS for clock_init and
|
||||
gpio_init.
|
||||
|
||||
If not defined, entry.c includes the code for clock_init and
|
||||
gpio_init which might be different to a board, and use them (entries
|
||||
in SYS will not be used). This works well with the ROM of SYS
|
||||
1.0.
|
||||
|
||||
Note that SYS entries of clock_init and gpio_init were introduced
|
||||
in SYS 2.0. So, enable this macro only if the ROM is SYS 2.0 or
|
||||
later.
|
||||
|
||||
- USE_SYS_BOARD_ID
|
||||
|
||||
Define this macro in a driver to get "sys_board_id" in SYS, so
|
||||
that the driver can support various boards at runtime by changing
|
||||
the settings according to the board.
|
||||
|
||||
A simple driver could only support a single board, by the compile
|
||||
time (BOARD_ID in board-*.h) choice of of a settings.
|
||||
|
||||
Note that SYS entries of sys_board_id and sys_board_name were
|
||||
introduced in SYS 2.1. So, enable this macro only if the ROM is
|
||||
SYS 2.1 or later.
|
||||
|
||||
- USE_SYS3
|
||||
|
||||
By defining this, it will have same effect of defining both of
|
||||
USE_SYS_CLOCK_GPIO_SETTING and USE_SYS_BOARD_ID internally.

An Example of No-use of SYS

===========================

See example-fsm-55 for an example of no use of SYS.

While chopstx/entry.c defines vectors in ROM and RAM, those are simply
