如何调整STM32F4链接描述文件以实现闪存的分区预留？

问答对人有帮助，内容完整，我也想知道答案 0 我需要为STM32F405VGT6上的虚拟EEPROM仿真保留FLASH：我需要的页面位于闪存的扇区2和扇区3中，因此不在闪存区域的末尾。所以我需要这样的东西： MEMORY{RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128KCCMRAM (rw) : ORIGIN = 0x10000000, LENGTH = 64KFLASH (rx) : ORIGIN = 0x8000000, LENGTH = 32kEMULATED_EEPROM (rwx) : ORIGIN = 0x8008000 LENGTH=216kFLASH (rx) : ORIGIN = 0x8008000+216k, LENGTH = 1024k-(32k+216k)} 但是这个。不起作用。如何调整链接描述文件以实现闪存的分区预留？ File : stm32_flash.ld * Abstract : Linker script for STM32F405VG Device with 1024KByte FLASH, 128KByte RAM Set heap size, stack size and stack location according to application requirements.

答案对人有帮助，有参考价值 0 你的代码非常接近，只要给他们不同的名字，并确保一切都在正确的地方。你可以在那里添加一个额外的部分，但它需要特别标记代码中的内容，IMO不值得花费1.5％的总闪存。作为旁注，这样的设置往往会混淆我的调试器（不知道它是GDB本身还是QtCreator给GDB错误的数据）所以我最终使用不同的链接描述文件进行调试。 MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K CCMRAM (rw) : ORIGIN = 0x10000000, LENGTH = 64K FLASH_BOOT (rx) : ORIGIN = 0x8000000, LENGTH = 32k EMULATED_EEPROM (rwx) : ORIGIN = ORIGIN(FLASH_BOOT) + LENGTH(FLASH_BOOT), LENGTH=216k FLASH (rx) : ORIGIN = ORIGIN(EMULATED_EEPROM) + LENGTH(EMULATED_EEPROM), LENGTH = 1024k - LENGTH(FLASH_BOOT) - LENGTH(EMULATED_EEPROM) } SECTIONS { .isr_vector : { . = ALIGN(4); KEEP((.isr_vector)) /* Startup code / . = ALIGN(4); } >FLASH_BOOT / The program code and other data goes into FLASH / .text : { . = ALIGN(4); (.text) /* .text sections (code) / (.text) / .text* sections (code) / (.glue_7) /* glue arm to thumb code / (.glue_7t) /* glue thumb to arm code / (.eh_frame) KEEP ((.init)) KEEP ((.fini)) . = ALIGN(4); _etext = .; /* define a global symbols at end of code */ } >FLASH }

答案对人有帮助，有参考价值 0 你可以尝试（从未测试过自己） MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K CCMRAM (rw) : ORIGIN = 0x10000000, LENGTH = 64K FLASH_1 (rx) : ORIGIN = 0x8000000, LENGTH = 32k EMULATED_EEPROM (rwx) : ORIGIN = 0x8008000 LENGTH=216k FLASH (rx) : ORIGIN = 0x8008000+216k, LENGTH = 1024k-(32k+216k) } .text2 : { ... } >> FLASH_1 .isr_vector : { . = ALIGN(4); KEEP((.isr_vector)) /* Startup code */ . = ALIGN(4); } >FLASH_1 但是要在text2部分中放置任何内容（例如某些函数），您必须使用它们进行声明 __attribute__ ((section ("text2")))
