RT1170 support QSPI Flash (MX25L51245G )

Hi,

Can RT1170 support MX25L51245G for QSPI flash?

Do it need to modify the configuration file “evkmimxrt1170_flexspi_nor_config.c” to meet this chip?

If so, how to modify it? Which parameters should be modified?

Thanks for your support!

Best regards,

WJC

Re: RT1170 support QSPI Flash (MX25L51245G )

Hello @jeremyzhou

We are using the MX25L51245G external flash and RT1176 and have implemented the configuration shown below. It works flawlessly in XIP mode, but I would like to get a validation from you as well.

However, when running a multicore application in "Link application mode", the system hits a hardfault. Specifically, it triggers an assert due to the value read from the FlexCAN MCR register.

I am attaching some screenshots and my lookup table below for your reference.

M7 flash init(RAM):

M4 flash init(RAM):

hardfault for multicore(RAM):

Here is the lookup table configuration designed to support the software running seamlessly in both RAM and XIP (Execute-in-Place) modes:

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Can RT1170 support MX25L51245G for QSPI flash?
-- Yes.
2) Do it need to modify the configuration file “evkmimxrt1170_flexspi_nor_config.c” to meet this chip?
-- Yes, please refer to the below code.

const flexspi_nor_config_t qspiflash_config = {
    .memConfig =
        {
            .tag              = FLEXSPI_CFG_BLK_TAG,
            .version          = FLEXSPI_CFG_BLK_VERSION,
            .readSampleClksrc=kFlexSPIReadSampleClk_LoopbackFromDqsPad,
            .csHoldTime       = 3u,
            .csSetupTime      = 3u,
            // Enable DDR mode, Wordaddassable, Safe configuration, Differential clock
            .sflashPadType = kSerialFlash_4Pads,
            .serialClkFreq = kFlexSpiSerialClk_100MHz,
            .sflashA1Size  = 64u * 1024u * 1024u,
            .lookupTable =
                {
                    // Read LUTs
                    FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xEB, RADDR_SDR, FLEXSPI_4PAD, 0x20),
                    FLEXSPI_LUT_SEQ(DUMMY_SDR, FLEXSPI_4PAD, 0x06, READ_SDR, FLEXSPI_4PAD, 0x04),
                },
        },
    .pageSize           = 256u,
    .sectorSize         = 4u * 1024u,
    .blockSize          = 256u * 1024u,
