Hi,

I just found out that the values in my FRAM variables do not remain there after power off. I checked if the addresses of variables are really in the FRAM and they are. I tried delete initialization the variables but it did not help.

Do you have any idea where could be a problem?

    I hope I solved the problem ( I have not tested it so much deeply yet). I just added NOINIT into these two rows in cmd file.

        .my_data_fram	  : {}  > FRAM_DATA type=NOINIT	/* Saved my data in FRAM			 */
    .my_status_fram	  : {}  > FRAM_STATUS type=NOINIT /* Saved status of data in FRAM		 */
