Hi 

We are facing below issue with program not being excecuted from Flash, What to change in linker script to resoved this issue

Posting your linker script would surely be helpful.

You cannot rely on a public forum with volunteering fellow engineers to solve your problems.

Sorry, But do we have solution to this?

We had the same issue and I was able to get around it by commenting out one line in the function BOARD_BootClockRUN() located in board/clock_config.c as shown below.  I do not know why this solved the issue.

//SystemCoreClock = BOARD_BOOTCLOCKRUN_CORE_CLOCK;
