Hello!
I'm using TouchGFX for a project, LCD and touch module are OK, but I have some problems with the QSPI driver (W25Q128 module).
I'm able to compile all the code and I see QSPI flash memory as used, but it gives me an error in "final launch sequence".
After including stm32746g_qspi.h (well, my board is an H743, but this file is modified by the vendor Waveshare: even if the name seems wrong, as you can see, it includes H7 headers):
//This is the stm32746g_qspi.h initial part
...
#ifndef __STM32746G_QSPI_H
#define __STM32746G_QSPI_H
#ifdef __cplusplus
extern "C" {
#endif
/* Includes ------------------------------------------------------------------*/
#include "stm32H7xx_hal.h"
#include "w25q128fv.h"
...So I put some initialization lines in MX_QUADSPI_Init() function:
void MX_QUADSPI_Init(void)
{
hqspi.Instance = QUADSPI;
hqspi.Init.ClockPrescaler = 10;
hqspi.Init.FifoThreshold = 4;
hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_HALFCYCLE;
hqspi.Init.FlashSize = 23;
hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_2_CYCLE;
hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;
hqspi.Init.FlashID = QSPI_FLASH_ID_1;
hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE;
if (HAL_QSPI_Init(&hqspi) != HAL_OK)
{
Error_Handler();
}
BSP_QSPI_Init();
BSP_QSPI_MemoryMappedMode();
HAL_NVIC_DisableIRQ(QUADSPI_IRQn);
}The function BSP_QSPI_MemoryMappedMode() function is not present in vendor's stm32746g_qspi.c , so I wrote this :
uint8_t BSP_QSPI_EnableMemoryMappedMode(void)
{
QSPI_CommandTypeDef s_command;
QSPI_MemoryMappedTypeDef s_mem_mapped_cfg;
/* Configure the command for the read instruction */
s_command.InstructionMode = QSPI_INSTRUCTION_1_LINE;
s_command.Instruction = QUAD_INOUT_FAST_READ_CMD;
s_command.AddressMode = QSPI_ADDRESS_4_LINES;
s_command.AddressSize = QSPI_ADDRESS_24_BITS;
s_command.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;
s_command.DataMode = QSPI_DATA_4_LINES;
s_command.DummyCycles = W25Q128FV_DUMMY_CYCLES_READ_QUAD;
s_command.DdrMode = QSPI_DDR_MODE_DISABLE;
s_command.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY;
s_command.SIOOMode = QSPI_SIOO_INST_EVERY_CMD;
/* Configure the memory mapped mode */
s_mem_mapped_cfg.TimeOutActivation = QSPI_TIMEOUT_COUNTER_DISABLE;
s_mem_mapped_cfg.TimeOutPeriod = 0;
if (HAL_QSPI_MemoryMapped(&QSPIHandle, &s_command, &s_mem_mapped_cfg) != HAL_OK)
{
return QSPI_ERROR;
}
return QSPI_OK;
}and, in stm32746g_qspi.h
#define BSP_QSPI_MemoryMappedMode BSP_QSPI_EnableMemoryMappedModeFinally, I modified my linker file and after compiling (without error) I can see the ToughGFX ExtFlashSection loaded in QUAD SPI.
Thanks and Best Regards!
