Background Sector Switch Execution

Last updated: 2018-12-05
Question:
How can I influence Background Sector Switch (BSS) Execution?
Answer:
A BSS can be controlled via using Fee_SetMode API. In case the mode is set to MEMIF_MODE_FAST, the FEE is not allowed to execute a sector switch in the background. If the mode is set to MEMIF_MODE_SLOW, the FEE is allowed to execute a sector switch in the background. In case NvMDrvModeSwitch is enabled in your NvM configuration, NvM will call Fee_SetMode with corresponding parameters. Before NvM starts a multiblock request (i.e. NvM_ReadAll, NvM_WriteAll) it will set FEE to MEMIF_MODE_FAST. After these requests are finished, NvM will set the FEE back to MEMIF_MODE_SLOW. This entails a fast start-up and a fast shutdown, because no time-consuming sector switch will be executed.
