TMS570LC4357: F021 flash erase/program usage

Gobind Singh1

Part Number: TMS570LC4357

Hi,

I need to develop a dataloader for my project that can receive the data on a serial bus and then programs the flash. I was going through the documentation SPNU501H and SPNA140.

I will not be able to use the .lib files that are provided by the TI as I there is no source code available. (We need to show the traceability).

SPNA140 explains how to write our own functions to perform these operations but it says: "The F021 Flash API is still required for Flash initialization and bank selection." Is it possible to do these operations without using the APIs in the .lib file?

Thank you.

    Hi Gobind Singh,

    The F021 source code comes into secure software, we cannot share source code without a valid NDA with TI.

    Yes, it is correct. Even though you develop your own functions for write and erase using the SPNA148 application note but still you have to use .lib for initialization operations. And unfortunately, there is no other way to rectify this problem, the only way is that you have to get the valid NDA with TI.

    For this purpose, you have to contact the local TI sales team.
