TMS570LC4357: Details of Fapi_issueProgrammingCommand

Gobind Singh1

Part Number: TMS570LC4357

Tool/software:

I downloaded the 80MHz HCLK example from the related thread and was able to program the flash.

Now, I want to be able to program the flash without using the Fapi_issueProgrammingCommand() APIs, so I followed the instructions in SPNA148. I could not get that to working. Attached is the screenshot of the code that does not work.

But if I replace the highlighted statement with below statement, it works fine and programs the locations specified for Bank 7.

Return_Status = Fapi_issueProgrammingCommand((uint32_t*)FL_PROG_ADDR_B7,DataBuffer,8,0,0,Fapi_AutoEccGeneration);

This tells me there is something that "Fapi_issueProgrammingCommand" function performs that I do not understand. Any suggestions please?

Thank you.

Thanks Jagadish for the build.

I downloaded the code and when I try to run it, Fapi_initializeFlashBanks() function returns "Fapi_Error_InvalidHclkValue"

I have not changed anything in the code and I am running it on the launchpad kit available from TI (OSC CLK is 16MHz). Do I need to update the clock settings to make it work correctly?

Thank you.

That is strange, I too tested on launchpad only. And my OSC CLK is also 16Mhz.

I don't see any such issue at my end.

I closed and opened CCS, retried, it worked same as your screenshot. Not sure what was wrong before. Thanks.

Just one question before we close this thread, if I want to write more than 8 bytes of data, do I need to repeat the whole sequence or can I just repeat the below part of the code:

I never tested practically, however i think the part you shared should be enough.
