|
||
|
|
|
||
|
|
<p>For the MSP430 it is possible to select the MPU architecture. The flag <span class="samp">-m [mpu type]</span>
|
||
|
|
will select an appropriate linker script for selected MPU type. (To get a list of known MPUs
|
||
|
|
just pass <span class="samp">-m help</span> option to the linker).
|
||
|
|
|
||
|
|
<p><a name="index-MSP430-extra-sections-566"></a>The linker will recognize some extra sections which are MSP430 specific:
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dt><span class="samp">.vectors</span><dd>Defines a portion of ROM where interrupt vectors located.
|
||
|
|
|
||
|
|
<br><dt><span class="samp">.bootloader</span><dd>Defines the bootloader portion of the ROM (if applicable). Any code
|

|
||
|
|
<br><dt><span class="samp">.infomem</span><dd>Defines an information memory section (if applicable). Any code in
|
||

|
||
|
|
|
||
|
|
<br><dt><span class="samp">.infomemnobits</span><dd>This is the same as the <span class="samp">.infomem</span> section except that any code
|
||
|
|
in this section will not be uploaded to the MPU.
|
||

|
||
|
|
<br><dt><span class="samp">.noinit</span><dd>Denotes a portion of RAM located above <span class="samp">.bss</span> section.
