Code snippet

HAL1

HAL2 

/* Init and config sequence */
HAL_OSPI_Init(&ospi);





HAL_OSPI_DLYB_SetConfig(&ospi, 2);

/* */
hal_xspi_config_t HAL_XSPI_Global_Cfg_Struct;

HAL_XSPI_Init(&xspi, HAL_OCTOSPI);

HAL_XSPI_SetConfig(&xspi, &HAL_XSPI_Global_Cfg_Struct);

HAL_XSPI_DLYB_SetConfigDelay(&xspi, 2);
HAL_XSPI_DLYB_Enable(&xspi);

Key changes

  1. In HAL2, OSPI APIs are replaced by XSPI APIs (for example, HAL_OSPI_Init() becomes HAL_XSPI_Init()).

  2. In HAL2, delay block configuration uses HAL_XSPI_DLYB_SetConfigDelay() and can be enabled using HAL_XSPI_DLYB_Enable().
