Saving file in Flash

Other Parts Discussed in Thread: NOWECC, UNIFLASH

Hello,

After reading about the SECDED in flash, I have a question, accordingo to:

"The ECC values for all of the ATCM program memory space (flash banks 0 through 6) must be
programmed into the flash before SECDED is enabled. This can be done by generating the correct values
of the ECC with an external tool such as nowECC or may be generated by the programming tool"

This means I can't save a file to flash, or change it several times, during run time? Would it work if I disabled ECC?

    Hello Pablo,

    When you program flash at run time, you would be using the TI F021 Flash API. In this case, the corresponding ECC locations are automatically programmed along with the main array(s). So you don't have to disable ECC checking for the ATCM.

    The note you referred to applies to the flash being programmed via the JTAG interface using Uniflash or CCS, for example.
