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: #define FLASH_DUMMY_CYCLES 0x08 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, .controllerMiscOption = 0x10, .deviceType = kFlexSpiDeviceType_SerialNOR, .sflashPadType = kSerialFlash_4Pads, .serialClkFreq = kFlexSpiSerialClk_133MHz, //okuma hatasi olursa kFlexSpiSerialClk_120MHz .sflashA1Size = 64u * 1024u * 1024u, //64MB //Her acilista QE = 1.
