Question
Unable to establish communication between STM32L4R5ZI and S25FL128L(NOR Flash) via Quad SPI.
i have generated the code from STM32CubeMX for OctoSPI, but not able to establish communication with NOR Flash.
It get stuck at following line "if (HAL_OSPIM_Config(&hospi1, &OSPIM_Cfg_Struct, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)" and goes to hard-fault.
i have configured the OctoSPI in following manner in CubeMX,
OCTOSPI Mode : Quad Mode
Data [3:0] : Port1[3:0]
Control NCS : Port1 NCS
Clock Port : Port 1 CLK
