[ABANDONED] JLink overwriting RAM of STM32

Hi,

I connect JLink to STM32 MCU and use SWD ports for serial communication. I write some bytes into SRAM using JLink command line interface.
Once I disconnect and reconnect JLink, the bytes written in SRAM are overwritten. I am sure that my software is not doing any such thing.

I tried different options in linker file to freeze memory data, but nothing is working.

Am I missing something or is this an inbuilt feature of JLink ?

Thanks for the help in advance
