一、cl、vl、xl、ld、md、hd的含义

• startup_stm32f10x_ld_vl.s: for STM32 Low density Value line devices
• startup_stm32f10x_ld.s: for STM32 Low density devices
• startup_stm32f10x_md_vl.s: for STM32 Medium density Value line devices
• startup_stm32f10x_md.s: for STM32 Medium density devices
• startup_stm32f10x_hd.s: for STM32 High density devices
• startup_stm32f10x_xl.s: for STM32 XL density devices
• startup_stm32f10x_cl.s: for STM32 Connectivity line devices

二、启动文件如何选择

• cl：互联型产品，stm32f105/107系列
• vl：超值型产品，stm32f100系列
• xl：超高密度产品，stm32f101/103系列
• ld：低密度产品，FLASH小于64K
• md：中等密度产品，FLASH=64 or 128
• hd：高密度产品，FLASH大于128
