TMS320F280041: Question about Fapi_IssueProgrammingCommand

Green Deng

Part Number: TMS320F280041
Other Parts Discussed in Thread: C2000WARE

Dear team:

My customer has a questions about FlashAPI:

The customer wants to write 7 bytes to flash at a time:

oReturnCheck = Fapi_issueProgrammingCommand(((uint32 *)(WriteOffset)),DataBuffer, 7,
0, 0, Fapi_AutoEccGeneration);

Add 7-bit addresses each time, that is, write from 0x85000, 0x85007, 0x8500e... Respectively

Why can some addresses fail to write data when writing in this way?

Best regards

Hi Green,

I will answer the flash program question here. I would suggest to open a different post for the bootloader queries.

Regarding the Flash program question: Please search for below questions in this FAQ: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/951668/faq-faq-on-flash-api-usage-for-c2000-devices

Why do you have different programming modes for Flash programming function (Fapi_issueProgrammingCommand())?

When using Fapi_AutoEccGeneration mode, what is the minimum number of 16-bit words that can be programmed?

When using Fapi_AutoEccGeneration mode, for a given 128-bit aligned memory, can I program lower 64-bits at one time and upper 64-bits at another time?

Also, search for below question in this FAQ: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/951658/faq-faq-for-flash-ecc-usage-in-c2000-devices---includes-ecc-test-mode-linker-ecc-options

Why do you use align directive (ALIGN(x)) in the linker cmd files provided in the C2000Ware examples?

Thanks and regards,
Vamsi
