TMS570LS3137: F021 Flash API's

Part Number: TMS570LS3137

Hello,

I have few doubts on F021 flash API's used to erase, program and verify flash in TMS570LS3137 on-chip flash memory.

1. What is the difference between block erase and sector erase?

2. Regarding Flash programming API "Fapi_issueProgrammingCommand", what will happen if "u8DataBufferSizeInBytes" parameter is less than 16 bytes?

    For example "Fapi_issueProgrammingCommand" command is issued with "u8DataBufferSizeInBytes" parameter as 10. is the controller going to write 0xFF to other 6 memory locations?

3. what data should we expect in respective flash memory after a successful "Fapi_issueAsyncCommandWithAddress" command execution?

Thanks in advance.

Regards,

Kalyan

Thanks,

Kalyan

    Hi Kalyan,

    1. Flash API performs either sector erase or bank erase. In the example code, block erase function is to erase one or more than 1 sectors.
    2. Data not supplied is treated as 0xFF.
    3. If the data is programmed successfully. Fapi_Status_Success (0x0) should be returned.
