TMS320F28379D: FAPI Erase sector

Adria Perez Martinez

Part Number: TMS320F28379D

Hi,

I use Fapi_issueAsyncCommandWithAddress() API to erase FLASH sectors. But, within cmd file, I have a different sector definition than the one defined in the default cmd files. For example, I have a sector which embraces all FLASH addresses corresponding to standard sectors from A to E. In that case, what is erased if I pass the standard FLASH A sector origin address to the API, only standard sector A or the whole sector I have defined in cmd file (standard sectors from A to E are erased)?

Also, in case I had defined all sectors as standard cmd file defines what would be erased if I passed an address from the middle of the A sector?

Thanks in advance!

Best regards,

Adria

Adria,

Irrespective of what you define in your linker cmd files, erase happens only for individual standard sectors.
For your particular question, Sector A gets erased and not Sectors A to E.

Linker cmd file is used to assign sections to memories - it does not control the addresses passed for Flash erase and program operations. Please let us know if you have further questions on this.

Thanks and regards,
Vamsi

Hi Vamsi,

Thanks for your answer.
What happens if I pass an address contained between sectors A and B origin address?

Adria,

Sector A gets erased. However, please use only the sector start addresses. That will help you in the future when you may transition to another upgraded C2000 device.

Thanks and regards,
