STM32H753IIT6 HEX文件生成错误地包含几个RAM部分如何处理

问答对人有帮助，内容完整，我也想知道答案 0 我们遇到了 STM32H753IIT6 的问题，它包含几个 RAM 部分……即 ITCMRAM (0x00000000)、DTCMRAM (0x20000000)、RAM_D1 (0x24000000)、RAM_D2 (0x30000000)、RAM_D3 (0x38000000)。发生的问题：当专门将变量加载到 RAM_D2 和 RAM_D3 (0x30000000) 时，生成的 Hex 文件将此部分作为可加载部分包含在内，这反过来会导致 STM32CubeProgrammer 在尝试加载该部分时出现问题。当 (NOLOAD) 选项应用于链接描述文件时，它确实解决了问题，但是我们不喜欢这个选项，因为我们必须特别处理代码中的任何初始值...... 这是一个已知的问题？ /* **************************************************************************** File : LinkerScript.ld Author : STM32CubeIDE Abstract : Linker script for STM32H7 series 2048Kbytes FLASH and 1056Kbytes 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 检查 .MAP 文件，或使用 OBJCOPY 或 FROMELF 类型工具转储 .ELF，确定您在 .LD 文件中未正确管理的内容 ST 在 startup.s 中提供的初始化处理相当幼稚，Keil 有一个更多的表管理分散加载器，而 Arduino GNU 人员似乎在启动代码以及生成用于复制和归零的表方面也更重要多个部分的数据，进入多个内存范围。可能想仔细研究一下以获得想法/清晰度。通常在 RAM 中初始化数据的情况下，您需要将其存放在 FLASH 中，以便在启动时将其复制出来。ST 通过标签把它找出来 } >RAM_D1 AT> 闪存
