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

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

Posting your linker script would surely be helpful.

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;
