RT1021：使用 ROM_FLEXSPI_NorFlash_Erase() 擦除闪存扇区

你好

在 EVK 上，我试用了 SDK 25.03.00 中的 evkmimxrt1020_fsl_romapi 示例，它工作正常。

然后，我自己在另一个项目中进行了尝试。它失败了。

ROM_FLEXSPI_NorFlash_Erase() 返回 6001，表示 kStatus_ROM_FLEXSPI_InvalidSequence。

我不知道是哪个顺序。
这两个项目使用完全相同的结构：

    config->memConfig.tag              = FLEXSPI_CFG_BLK_TAG;
    config->memConfig.version          = FLEXSPI_CFG_BLK_VERSION;
    config->memConfig.readSampleClksrc=kFLEXSPIReadSampleClk_LoopbackInternally;
    config->memConfig.serialClkFreq =
        kFLEXSPISerialClk_30MHz; /* Serial Flash Frequencey.See System Boot Chapter for more details */
    config->memConfig.sflashA1Size   = FLASH_SIZE;
    config->memConfig.csHoldTime     = 3U;                           /* Data hold time, default value: 3 */
    config->memConfig.csSetupTime    = 3U;                           /* Date setup time, default value: 3 */
    config->memConfig.deviceType     = kFLEXSPIDeviceType_SerialNOR; /* Flash device type default type: Serial NOR */
    config->memConfig.deviceModeType = kDeviceConfigCmdType_Generic;
    config->memConfig.columnAddressWidth  = 0U;
    config->memConfig.deviceModeCfgEnable = 0U;
    config->memConfig.waitTimeCfgCommands = 0U;
    config->memConfig.configCmdEnable     = 0U;
    /* Always enable Safe configuration Frequency */
    config->memConfig.controllerMiscOption = FSL_ROM_FLEXSPI_BITMASK(kFLEXSPIMiscOffset_SafeConfigFreqEnable);
    config->memConfig.sflashPadType = kSerialFlash_4Pads; /* Pad Type: 1 - Single, 2 - Dual, 4 - Quad, 8 - Octal */
    config->pageSize                = FLASH_PAGE_SIZE;
    config->sectorSize              = FLASH_SECTOR_SIZE;
    config->blockSize               = FLASH_BLOCK_SIZE;
    config->ipcmdSerialClkFreq      = kFLEXSPISerialClk_30MHz; /* Clock frequency for IP command */

    /* Fast Read Quad I/O */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_READ + 0U] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xebU, RADDR_SDR, FLEXSPI_4PAD, 0x18U);
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_READ + 1U] =
        FSL_ROM_FLEXSPI_LUT_SEQ(DUMMY_SDR, FLEXSPI_4PAD, 0x06U, READ_SDR, FLEXSPI_4PAD, 0x4U);

    /* Read Status */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_READSTATUS] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0x05U, READ_SDR, FLEXSPI_1PAD, 0x1U);

    /* Write Enable */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_WRITEENABLE] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0x06U, STOP, FLEXSPI_1PAD, 0x0U);

    /* Page Program - quad mode */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_PAGEPROGRAM + 0U] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0x32U, RADDR_SDR, FLEXSPI_1PAD, 0x18U);
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_PAGEPROGRAM + 1U] =
        FSL_ROM_FLEXSPI_LUT_SEQ(WRITE_SDR, FLEXSPI_4PAD, 0x04U, STOP, FLEXSPI_1PAD, 0x0U);

    /* Sector Erase */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_ERASESECTOR] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xD7U, RADDR_SDR, FLEXSPI_1PAD, 0x18U);

    /* Block Erase */
    config->memConfig.lookupTable[4U * NOR_CMD_LUT_SEQ_IDX_ERASEBLOCK] =
        FSL_ROM_FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xD8U, RADDR_SDR, FLEXSPI_1PAD, 0x18U);

此外，在这两个项目中，我在调用 ROM_FLEXSPI_NorFlash_Erase() 之前立即验证了 LUT。这些值完全匹配（我还打印了未打包的值）：

我深信一定存在差异，但我已不知道该去哪里寻找。

两个项目都在 RAM 中运行，时钟配置完全相同。

我应该把问题的重点放在哪里？

您好@Sam_Gao

我解决了它。问题出在错误的擦除地址上，但错误代码kStatus_ROM_FLEXSPI_InvalidSequence却让我想到了一个完全不同类型的问题，因此我在相当长的一段时间里都把注意力放在了错误的事情上。

顺祝商祺！

这似乎是无效序列中的一些问题。我能知道这两个项目是否都来自恩智浦的官方示例，并在同一个EVK板上为你进行了测试吗？
