[参考译文] RM46L852：launchxl2-rm46L852 FreeRTOS 闪烁 LED

您好 Fabian、

[引用 userid="505290" URL"~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1055524/rm46l852-launchxl2-rm46l852-freertos-blinking-led "]我遇到了一些 FreeRTOS 以及 halcogen 生成的代码问题[/quot]

问题是什么？ 编译工程时是否有任何错误？  您是否按照 HALCoGen 帮助中的步骤配置器件？

我刚刚在 CCS 11中导入了您的项目、并收到了相同的警告：

这些警告意味着链接器未看到在链接器命令文件中指定的段、因此将命名段放置在任意的存储器区域中。

 RM46L852/Debug/RM46L852.MAP 链接映射文件显示 .kernelTEXT、 .kernelHEAP 和 .kernelBSS 段都已放置在 FLASH0中。  需要 将.kernelHEAP 和.kernelBSS 段放置在 RAM 中、并会导致程序在闪存中运行时失败(正如链接器命令文件中未指定的段所发生的那样)。

查看构建中的链接器命令行、CCS 工程将 RM46L852/Third_party/HAL/source/sys_link.cmd 链接器命令文件传递给链接器。 在链接器命令文件中，段不包含 .kernelTEXT、 .kernelHEAP 或.kernelBSS：

SECTIONS
{
    .intvecs : {} > VECTORS
    .text    : {} > FLASH0 
    .const   : {} > FLASH0 
    .cinit   : {} > FLASH0 
    .pinit   : {} > FLASH0 
    .bss     : {} > RAM
    .data    : {} > RAM
    .sysmem  : {} > RAM
    
    FEE_TEXT_SECTION : {} > FLASH0 
    FEE_CONST_SECTION : {} > FLASH0
    FEE_DATA_SECTION : {} > RAM

/* USER CODE BEGIN (4) */
/* USER CODE END */
}

 RM46L852_FreeRTOS/SOURCE/SYS_LINK_cmd 链接器命令文件包含 .kernelTEXT、 .kernelHEAP 和 .kernelBSS 段：

SECTIONS
{
    .intvecs : {} > VECTORS
    /* FreeRTOS Kernel in protected region of Flash */
    .kernelTEXT   : {} > KERNEL
    .cinit        : {} > KERNEL
    .pinit        : {} > KERNEL
    /* Rest of code to user mode flash region */
    .text         : {} > FLASH0 
    .const        : {} > FLASH0 
    /* FreeRTOS Kernel data in protected region of RAM */
    .kernelBSS    : {} > KRAM
    .kernelHEAP   : {} > RAM
    .bss          : {} > RAM
    .data         : {} > RAM    

/* USER CODE BEGIN (4) */
/* USER CODE END */
}

看起来 CCS 工程的设置方式、FreeRTOS 的正确链接器命令文件尚未使用。

顶级 RM46L852_FreeRTOS 和 RM46L852目录是如何设置的？

切斯特、您好！

感谢您的详细回答、这有助于我了解这些警告的来源。

我已经在该目录中执行了很多操作、我将尝试从干净的设置中执行。

感谢您的付款帮助！

此致、

如果您将  RM46L852_FreeRTOS/SOURCE /SYS_LINK_cmd 文件复制到 RM46L852/Third_party/HAL/ SOURCE 目录中、即覆盖现有 RM46L852/Third_party/HAL/source/sys_link.cmd、则会删除这些警告。 我刚刚尝试过、没有链接器警告、链接器映射文件显示了看起来正确的段放置方式：

  08003b28    08003b28    0000001c   00000000    rw- .data

但是、将 RM46L852目录设置为具有 FreeRTOS 支持的 HALCoGen 生成的项目可能更容易维护、因此可以在需要时重新生成 HALCoGen 代码。

切斯特、抱歉、我在看到您回答问题之前重新编辑了我的答案...

实际上、如果我将 RM46L852_FreeRTOS/SOURCE /SYS_LINK_cmd 文件复制到 RM46L852/Third_party/HAL/source 目录中、它会删除这些警告、感谢您！

但我使用 launchpad 测试了代码、但它不起作用。 我仍在执行任务创建... 我想我将尝试使用具有最低 FreeRTOS 功能的 HALCOGEN 重新生成项目。 非常感谢 Chester 的帮助。
