<h3><a name="newboardconfig">2.4.4 Adding a New Board Configuration</a></h3>
|
||||
<p>
|
||||
Okay, so you have created a new board configuration directory.
|
||||
Now, how do you hook this board into the configuration system so that you can select with <code>make menuconfig</code>?
|
||||
</p>
|
||||
<p>
|
||||
You will need modify the file <code>configs/Kconfig</code>.
|
||||
Let's look at the STM32F4-Discovery configuration in the <code>Kconfig</code> file and see how we would add a new board directory to the configuration.
|
||||
For this configuration let's say that you new board resides in the directory <code>configs/myboard</code>;
|
||||
It uses an MCU selected with <code>CONFIG_ARCH_CHIP_MYMCU</code>; and you want the board to be selected with <code>CONFIG_ARCH_BOARD_MYBOARD</code>.
|
||||
Then here is how you can clone the STM32F4-Discovery configuration in <code>configs/Kconfig</code> to support your new board configuration.
|
||||
</p>
|
||||
<p>
|
||||
In <code>configs/Kconfig</code> for the stm32f4-discovery, you will see a configuration definition like this:
|
||||
<p>
|
||||
<ul><pre>
|
||||
config ARCH_BOARD_STM32F4_DISCOVERY
|
||||
bool "STMicro STM32F4-Discovery board"
|
||||
depends on ARCH_CHIP_STM32F407VG
|
||||
select ARCH_HAVE_LEDS
|
||||
select ARCH_HAVE_BUTTONS
|
||||
select ARCH_HAVE_IRQBUTTONS
|
||||
---help---
|
||||
STMicro STM32F4-Discovery board based on the STMicro STM32F407VGT6 MCU.
|
||||
</pre></ul>
|
||||
<p>
|
||||
The above selects the STM32F4-Discovery board.
|
||||
The <code>select</code> lines say that the board has both LEDs and buttons and that the board can generate interrupts from the button presses.
|
||||
You can just copy the above configuration definition to a new location (notice that they the configurations are in alphabetical order).
|
||||
Then you should edit the configuration to support your board.
|
||||
The final configuration definition might look something like:
|
||||
</p>
|
||||
<ul><pre>
|
||||
config ARCH_BOARD_MYBOARD
|
||||
bool "My very own board configuration"
|
||||
depends on ARCH_CHIP_MYMCU
|
||||
select ARCH_HAVE_LEDS
|
||||
select ARCH_HAVE_BUTTONS
|
||||
select ARCH_HAVE_IRQBUTTONS
|
||||
---help---
|
||||
This options selects the board configuration for my very own board
|
||||
based on the MYMCU processor.
|
||||
</pre></ul>
|
||||
<p>
|
||||
Later in the <code>configs/Kconfig</code> file, you will see a long, long string configuration with lots of defaults like this:
|
||||
</p>
|
||||
<ul><pre>
|
||||
config ARCH_BOARD
|
||||
string
|
||||
default "amber" if ARCH_BOARD_AMBER
|
||||
default "avr32dev1" if ARCH_BOARD_AVR32DEV1
|
||||
default "c5471evm" if ARCH_BOARD_C5471EVM
|
||||
...
|
||||
default "stm32f4discovery" if ARCH_BOARD_STM32F4_DISCOVERY
|
||||
...
|
||||
</pre></ul>
|
||||
<p>
|
||||
This logic will assign string value to a configuration variable called <code>CONFIG_ARCH_BOARD</code> that will name the directory where the board-specific files reside.
|
||||
In our case, these files reside in <code>configs/myboard</code> and we add the following to the long list of defaults (again in alphabetical order):
|
||||
</p>
|
||||
<ul><pre>
|
||||
default "myboar" if ARCH_BOARD_MYBOARD
|
||||
</pre></ul>
|
||||
<p>
|
||||
Now the build system knows where to find your board configuration!
|
||||
</p>
|
||||
<p>
|
||||
And finally, add something like this near the bottom of <code>configs/myboard</code>:
|
||||
</p>
|
||||
<ul><pre>
|
||||
if ARCH_BOARD_MYBOARD
|
||||
source "configs/myboard/Kconfig"
|
||||
endif
|
||||
</pre></ul>
|
||||
<p>
|
||||
This includes additional, board-specific configuration variabled defintion in <code>configs/myboard/Kconfig</code>.

||||
