| <h3 class="section">4.8 <code>ld</code> and MSP430</h3> |
| |
| <p>For the MSP430 it is possible to select the MPU architecture. The flag ‘<samp><span class="samp">-m [mpu type]</span></samp>’ |
| will select an appropriate linker script for selected MPU type. (To get a list of known MPUs |
| just pass ‘<samp><span class="samp">-m help</span></samp>’ option to the linker). |
| |
| <p><a name="index-MSP430-extra-sections-613"></a>The linker will recognize some extra sections which are MSP430 specific: |
| |
| <dl> |
| <dt><code>‘</code><samp><span class="samp">.vectors</span></samp><code>’</code><dd>Defines a portion of ROM where interrupt vectors located. |
| |
| <br><dt><code>‘</code><samp><span class="samp">.bootloader</span></samp><code>’</code><dd>Defines the bootloader portion of the ROM (if applicable). Any code |
| in this section will be uploaded to the MPU. |
| |
| <br><dt><code>‘</code><samp><span class="samp">.infomem</span></samp><code>’</code><dd>Defines an information memory section (if applicable). Any code in |
| this section will be uploaded to the MPU. |
| |
| <br><dt><code>‘</code><samp><span class="samp">.infomemnobits</span></samp><code>’</code><dd>This is the same as the ‘<samp><span class="samp">.infomem</span></samp>’ section except that any code |
| in this section will not be uploaded to the MPU. |
| |
| <br><dt><code>‘</code><samp><span class="samp">.noinit</span></samp><code>’</code><dd>Denotes a portion of RAM located above ‘<samp><span class="samp">.bss</span></samp>’ section. |
| |
| <p>The last two sections are used by gcc. |
