我的客户希望在 EasyLink 示例中使用自动堆大小以节省 RAM 存储器。 TI15.4和 BLE 用户指南中的现有指南基于 TI-RTOS6、这不适用于新的 TI-RTOS7项目。 您能否帮助您在 TI-RTOS7中使用 HeapMem 或 HeapCallback 启用自动堆大小？
客户的项目基于 SDK6.20中的 rfEasyLinkListenBeforeTalk、谢谢。

您好、Shuyang、
我认为应该可以在编译时使用 TI RTOS 6中的相同机制来设置堆大小。
在 TI-RTOS7中、堆参数在 SysConfig -> TI RTOS -> BIOS ->默认堆设置中定义。 默认情况下、该示例使用 HeapMem 模块。
堆开始和结束使用 __primary_heap_start__和 __primary_heap_end__变量定义。 您可以在链接器命令文件 cc13x2_cc26x2_tirtos7.cmd 中找到这些命令。
/* Section allocation in memory */
SECTIONS
{
// ...
.nonretenvar : > SRAM
/* Heap buffer used by HeapMem */
.priheap : {
__primary_heap_start__ = .;
. += HEAPSIZE;
__primary_heap_end__ = .;
} > SRAM align 8
.gpram : > GPRAM
.log_data : > LOG_DATA, type = COPY
}
如果用编译时定义替换此定义、则应该具有可变的堆大小。 例如、使用 BLE-Stack 中的链接器命令文件(cc13x2_cc26x2_app_tirtos7.cmd)作为示例。 此处的相关变量称为 heapstart 和 heapend。
/*******************************************************************************
* Section Allocation in Memory
******************************************************************************/
SECTIONS
{
// ...
GROUP > SRAM
{
// ...
} LOAD_END(heapStart)
.stack : > SRAM (HIGH) LOAD_START(heapEnd)
谢谢、

您好、Marie、
我正在尝试将 rfEasyLinkListenBeforeTalk CC1352P1_LAUNCHXL_tirtos7_climang 的堆配置更改为自动调整堆大小。 我从 TI15.4-stack 传感器示例中复制了.cmd 文件、并相应地更改默认堆设置：
我还修改了.syscfg 文件中的 BIOS 设置、如下所示：
/* * Runtime instance creation enable flag. * * Pick one: * - true (default) * Allows Mod_create() and Mod_delete() to be called at runtime which * requires a default heap for dynamic memory allocation. * - false * Reduces code footprint by disallowing Mod_create() and Mod_delete() to * be called at runtime. Object instances are constructed via * Mod_construct() and destructed via Mod_destruct(). * * When using BIOS in ROM: * This option must be set to true. */ BIOS.runtimeCreatesEnabled = true; //BIOS.runtimeCreatesEnabled = false; BIOS.rtsGateType = "BIOS_GateMutexPri"; BIOS.heapSize = 0x00000000; //BIOS.heapBaseAddr = "__primary_heap_start__"; //BIOS.heapEndAddr = "__primary_heap_end__"; BIOS.heapType = "HeapCallback";
之后、我将 rtos_heaposal.h 从 \simplelink_cc13xx_cc26xx_sdk_6_20_00_29\sources\ti154stack\common\heapmgr 复制到我的项目文件、并添加了预定义符号 TIRTOS7_support、HEAPMGR_CONFIG=0x80和 HEAPMGR_SIZE=0x0。
但是、编译错误仍然存在、如下所示：

我错过了什么？

您好、Shuyang、
要尝试以下几项操作：
1) 1)将 heapmgr 文件夹添加到编译器搜索路径：
2) 2)您能否发布.syscfg 文件？
谢谢、
