The only difference is the <strong>linker script</strong>.</p> <h2 id="linker-script">Linker Script</h2> <p>STM32 linker scripts are also designed for reusability, divided into two parts:</p> <ul> <li>Linker script in the SDL: Describes how various sections are distributed in the image file <ul> <li>STM32F0: <code>XWOS/xwcd/soc/arm/v7m/m0/stm32/f0.lds</code></li> <li>STM32G0: <code>XWOS/xwcd/soc/arm/v7m/m0p/stm32/g0.lds</code></li> <li>STM32F1: <code>XWOS/xwcd/soc/arm/v7m/m3/stm32/f1.lds</code></li> <li>STM32L1: <code>XWOS/xwcd/soc/arm/v7m/m3/stm32/l1.lds</code></li> <li>STM32F4: <code>XWOS/xwcd/soc/arm/v7m/m4/stm32/f4.lds</code></li> <li>STM32L4: <code>XWOS/xwcd/soc/arm/v7m/m4/stm32/l4.lds</code></li> <li>STM32F7: <code>XWOS/xwcd/soc/arm/v7m/m7/stm32/f7.lds</code></li> <li>STM32H7: <code>XWOS/xwcd/soc/arm/v7m/m7/stm32/h7.lds</code></li> <li>Other SoCs are continuously being added&hellip;</li> </ul> </li> <li>Linker script in the board directory: Only describes memory regions</li> <li>WeActMiniStm32H750 project: <code>XWOS/xwbd/WeActMiniStm32H750/cfg/brd.lds</code></li> <li>WeActMiniStm32H750Bootloader project: <code>XWOS/xwbd/WeActMiniStm32H750Bootloader/cfg/brd.lds</code></li> <li>Other boards are continuously being added&hellip;</li> </ul> <p>Different board projects only differ in the Memory regions in the Board linker script.</p>
