TMS570LS0714: Preserving variable value throughout startup

Lana B

Part Number: TMS570LS0714

I would like to keep track of the results of all built-in self tests performed at startup, but all the variables get erased during memory initialization. Is there a way I could store those values for later access?

    Hello Lana,

    The contents of the selected memory before the initialization will be completely lost. User software must take care of data backup if required.

    1. copy the data to other RAM region which doesn't require initialization or test. For example, MibSPI RAM or CAN RAM
    2. you can write the data to flash or EEPROM
