HAL SDRAM IRQ handler and callbacks functions migration ¶

This section provides information about the HAL SDRAM control functions migration.

HAL SDRAM unregister, register and DMA callbacks ¶

HAL1	HAL2
HAL_SDRAM_UnRegisterCallback(); HAL_SDRAM_RegisterDmaCallback(); HAL_SDRAM_DMA_XferCpltCallback(); HAL_SDRAM_DMA_XferErrorCallback();	Removed: No specific configuration or handling needed. No more Read/write APIs use in HAL SDRAM driver.

HAL SDRAM register callback ¶

HAL1	HAL2
HAL_SDRAM_RegisterCallback(&hsdram, HAL_SDRAM_REFRESH_ERR_CB_ID); // Other callbacks are removed	HAL_SDRAM_RegisterRefreshErrorCallback(&hsdram); Note The register callback existe only for “RefreshError”.
