Emma,

Flash and OTP memories on this device support SECDED (Single error correction and double error detection). Please find more details in TRM's Flash chapter. To use this feature, user should program ECC (Error correction code) for the these memories at the above ECC addresses. User when loading code in to flash using CCS or Uniflash should enable AutoEccGeneration in the GUI - It is enabled by default - This option will calculate and program ECC automatically for the flash/OTP. All the 3rd party programmers also support programming ECC.

Is the user planning to use flash API to program flash?

Thanks and regards,
Vamsi

Vamsi,

Thanks, it is very clear.

Customer is not asking update code related questions.

By the way,

Emma,

Ok. If customer wants to program flash using flash API (by their custom loaders etc), then they need to program ECC using Fapi_AutoEccGeneration mode.

You can get more details about it in flash API guide (https://www.ti.com/lit/pdf/spnu631) and below FAQs:
