[参考译文] SK-AM62P-LP：DCC /ESM 未为 MCU_DCC1生成中断(MCU_SPI 0&amp；MCU_SPI 1)

工具与软件：

专家、您好！

董事会:SK-AM62P-LP

操作系统: Processor SDK Linux RT AM62P Debian Trixie -版本: 10.00.07.04.

MCU+SDK：版本：10.00.07.04

我们正在监控 MCU_DDC1的时钟、以跟踪 MCU_SPI 外设时钟的频率、该时钟频率源自 MCU_PLL0_HISTDIVE 6。 我修改了提供的示例代码并尝试了错误注入 CLOCKSRC1 . 不过、当注入错误时、没有按预期触发错误中断。

为了捕获错误、我在中启用了第36个错误事件 WAKEUP_ESM0 . 下面是供您参考的相关代码片段：

SDL_ESM_config DCC_Test_esmInitConfig_Inst =
{

     /**< All high priority events to error pin */
        .esmErrorConfig = {1u, 8u}, /* Self test error config */
    .enableBitmap = {0x00000000u, 0x00000007bu, 0x00000000u, 0x00003000u,
                 0x00000000u, 0x00000380u,

                },
     /**< All events enable: except clkstop events for unused clocks
      *   and PCIE events */
    .priorityBitmap = {0x00000000u, 0x00000007bu, 0x0000000u, 0x00003000u,
                 0x00000000u, 0x00000380u,

                        },
    /**< All events high priority: except clkstop events for unused clocks
     *   and PCIE events */
    .errorpinBitmap = {0x00000000u, 0x00000007bu, 0x00000000u, 0x00003000u,
                 0x00000000u, 0x00000380u,

                      },
    /**< All events high priority: except clkstop for unused clocks
     *   and PCIE events */


};
SDL_ESM_config DCC_Test_esmInitConfig_Main =
{


  /**< All high priority events to error pin */
        .esmErrorConfig = {1u, 8u}, /* Self test error config */
    .enableBitmap = {0x00000000u, 0x000000078u, 0x00008000u,0x003f3000u,
                 0x00000000u, 0x00000380u,

                },
     /**< All events enable: except clkstop events for unused clocks
      *   and PCIE events */
    .priorityBitmap = {0x00000000u, 0x000000078u, 0x00008000u,0x003f3000u,
                 0x00000000u, 0x00000380u,
                        },
    /**< All events high priority: except clkstop events for unused clocks
     *   and PCIE events */
    .errorpinBitmap = {0x00000000u, 0x000000078u, 0x00008000u,0x003f3000u,
                 0x00000000u, 0x00000380u,

                      },
    /**< All events high priority: except clkstop for unused clocks
     *   and PCIE events */


 };

由于我不使用任何单个短模式、因此我不必注册任何完成中断(如果没有错误)。

下面是 DCC 配置数组。

     {
         "HFOSC0",
         "MCU_SPI (0/1) /MCUPLL0_HSDIV6",
          SDL_DCC_INST_MCU_DCC1,
          SDL_DCC_CLK0_SRC_CLOCK0_0,
          25000, /* 25 MHz for HFOSC0 */
          SDL_DCC_CLK1_SRC_CLOCKSRC1,
          400000, /* 400 MHz for SYSCLK0 */
          SDL_DCC_MODE_CONTINUOUS,
          0x0,
          0xffff,
          IS_ERR
        },

谢谢、此致、

Raj。
