您好！


我正在尝试设置由主域中引脚 Y1上的引脚 PRG0_PRU0_GPO0 (GPIO1_0)触发的中断。  ISR 必须由 R5FSS1_CORE0提供服务。  当我配置 GPIO 引脚为中断提供服务时、SysConfig 生成了以下文件(ti_drivers_config.c)、其中包含设置中断的代码。  但是，当在 ti_drivers_config.c 中调用 Sciclient_gpioIrqSet()时，对 Sciclient_rmIrqSet()的调用失败。  
随附了我的 example.syscfg 和 ti_drivers_config.c 文件：

e2e.ti.com/.../4747.ti_5F00_drivers_5F00_config.c

示例.syscfg： 

/**

 * via the GUI or CLI. Run CLI with '--help' for additional information on how to override these arguments.
 * @cliArgs --device "AM243x_ALV_beta" --package "ALV" --part "ALV" --context "r5fss1-0" --product "MCU_PLUS_SDK_AM243x@08.04.00"

根据相关的支持请求、我需要进行修改 sources\drivers\sciclient\sciclient_default_boardcfg\am64x_am243x\sciclient_defaultBoardcfg_rm.c 以完成从中断源到请求内核(R5FSS1_CORE0)的管道。  如何修改该文件以将 GPIO1_0连接到 R5FSS1_CORE0？  是否有描述此过程的文档(AM243x MCU+ SDK 文档的"修改资源分配"部分除外)？  相关的支持请求对于如何执行此操作不是很清楚、我在阅读相关的支持请求单或 SDK 文档时也不清楚"启动资源"和"num_resource"在配置的"资源类型"中指的是什么。

它非常令人困惑。

如果有任何帮助，将不胜感激。

谢谢。

    您好、Scott、

    [引用 userid="521726" URL"~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1164540/am2432-how-to-connect-a-gpio-input-interrupt-to-a-specific-r5-core "]是否有一个介绍此过程的文档(AM243x MCU+ SDK 文档的"修改资源分配"部分除外)？

    否、目前没有更好地描述此过程的文档。 但是、SDK 08.05中将进行更新、以简化 RM 更改。

    您好、Frank、

    常见问题解答帮助了-我现在看到了资源的定义位置，但是对 Sciclient_rmIrqSet()的调用仍然失败(返回-1)。  我的设置如下：

    用于 ISR 的内核为 R51_Core0、因此 sciclient_defaultBoardcfg_rm.c 中的条目为：

           ｛
               num_resource = 2、
               .type = TISCI_RESSASG_UTYPE (TISCI_DEV_MAIN_GPIOMUX_INTROUTER0、TISCI_RESSASG_SUBTYPE_IR_OUTPUT)、
               .start_resource = 12、
               .host_id = TISCI_HOST_ID_MAIN_1_R5_1、
           }、

    GPIO 引脚配置如下：

          GPIO1_0 (引脚 Y1)、输入、上升沿、ROUTER12或 ROUTER13。选中启用中断配置复选框后。

    SysConfig 生成以下代码(使用 ROUTER13)： 

    /* This is based on DMSC board config and core */
#define BOARD_BUTTON_GPIO_INTR_NUM     (CSLR_R5FSS0_CORE0_INTR_MAIN_GPIOMUX_INTROUTER0_OUTP_13)

/*GPIO Interrupt Macros */
#define BOARD_BUTTON_GPIO_SWITCH_NUM    (5)

/** \brief bank interrupt source index base */

        DebugP_log("[Error] Sciclient event reset failed!!!\r\n");
        DebugP_assert(FALSE);
    }
    return;
}
    ：

    对 Sciclient_rmIrqSet()的调用返回-1。  Sciclient_rmIrqSet()调用树中的函数 Sciclient_rmIrqFindRoute()生成错误。  ROUTER12的故障方式相同。

    这看起来是正确的、还是我错过了什么？

    此致、

    Scott

    您好、Scott、

    我为使用 GPIO1_0 (Y1)的 R51_0创建了一个新示例。

    对于主域 GPIO IR、我看到 IR 输入180 (主 GPIO 组 Int 0)路由到 IR 输出12：

    在默认的 RM 文件(sciclient_defaultBoardcfg_rm.c)中、IR 输出12分配给 R51_Core0、VIM 中断#44。

    我已附加完整的 CCS 项目。 请告诉我这是否有帮助。
