TMS570LC4357: Flashbank space

Part Number: TMS570LC4357

Hi Exrperts,

I need your advice, is it possible that after my program was written on flashbank0, can I use other remaining space on flashbank0?

Thanks!

Regards,

Hi Marvin,

Yes. You can use F021 flash APIs to erase the remaining sectors of Bank 0 and program your data to those sectors.

Hi Qj,

Follow-up question: If I want to use flashbank 7, I can not use the related library functions of FEE. How many bytes can flashbank7 write at most once?

Thank you for the support.

Regards,

Marvin

Hi Marvin,

The bank 7 is 128KB in size, and a minimum of two Virtual Sectors are required for Flash EEPROM emulation. The max size of a virtual sector is 64KB. The size of all the Data Blocks cannot exceed the Virtual Sector length.
