STM32H7B0 HAL OSPI配置的一次失败原因分享

使用 OSPI1 驱动W25Q128，但是始终无法调试成果，最后发现是HAL 库的问题

我使用的HAL库是CUBEMX自动生成的，CUBEMX版本是6.4

HAL库在这个函数中存在错误：
HAL_StatusTypeDef HAL_OSPI_Init (OSPI_HandleTypeDef *hospi)

      MODIFY_REG(hospi->Instance->DCR1,
                 (OCTOSPI_DCR1_MTYP | OCTOSPI_DCR1_DEVSIZE | OCTOSPI_DCR1_CSHT | OCTOSPI_DCR1_CKCSHT |
                  OCTOSPI_DCR1_FRCK | OCTOSPI_DCR1_CKMODE),
                 (hospi->Init.MemoryType | ((hospi->Init.DeviceSize - 1U) << OCTOSPI_DCR1_DEVSIZE_Pos) |
                  ((hospi->Init.ChipSelectHighTime - 1U) << OCTOSPI_DCR1_CSHT_Pos) |
                  (hospi->Init.ClkChipSelectHighTime << OCTOSPI_DCR1_CKCSHT_Pos) | hospi->Init.ClockMode));

替换成

      /* Configure memory type, device size, chip select high time, clocked chip select high time, delay block bypass, free running clock, clock mode */
      MODIFY_REG(hospi->Instance->DCR1,
                 (OCTOSPI_DCR1_MTYP   | OCTOSPI_DCR1_DEVSIZE | OCTOSPI_DCR1_CSHT | OCTOSPI_DCR1_CKCSHT |
                  OCTOSPI_DCR1_DLYBYP | OCTOSPI_DCR1_FRCK    | OCTOSPI_DCR1_CKMODE),
                 (hospi->Init.MemoryType | ((hospi->Init.DeviceSize - 1U) << OCTOSPI_DCR1_DEVSIZE_Pos) |
                  ((hospi->Init.ChipSelectHighTime - 1U) << OCTOSPI_DCR1_CSHT_Pos) |
                  (hospi->Init.ClkChipSelectHighTime << OCTOSPI_DCR1_CKCSHT_Pos) |
                  hospi->Init.DelayBlockBypass | hospi->Init.ClockMode));

问题就解决了。
