- FOTA Logic Power saving:
All FOTA logic except FOTA MMR can be clock gated when FOTA logic is not used.
By default, the clock to FOTA logic is enabled to make it easier for loading the
firmware etc. However, during initialization, software can enable clock gating
by setting FOTA_INIT.clkdis MMR bit in FSAS_FOTA_GENREGS region. Software
needs to enable clocks during FOTA sequence and disable them after FOTA sequence
is done. This will ensure the logic is not consuming unnecessary power.
- OSPI Controller Autopolling
: Read While Write (RWW) flash devices allow read access while write in a
different bank is ongoing. Please note that if auto polling is enabled, OSPI
Controller will block read access until flash write is fully complete. As a
result, auto polling has to be disabled in OSPI Controller in order to utilize
RWW capability of the flash. Auto polling can be performed by FOTA firmware if
required.
Note: TI will provide the FOTA MCU firmware binary as part of SDK
offering. Please contact a TI representative for the same.
