Boot loader and Jumping to the application has nothing to do with RTOS. You need to link application to different flash offset and you also need to change the vector table offset in application.

Can you elaborate more about what exactly need to do

Yes i did with out RTOS running Fine with RTOS not going to application

Depends on the USER/SYSTEM state, and also if interrupt contexts have been stacked.​

Code in Reset Handler to recognize signature in RAM and do control transfer to App and code in Loader to validate App, place signature and NVIC_SystemReset

Try show code and dont write about RTOS, because if you dont use it in bootloader , isnt source of your problem , only detector...

"Break at address "0x808d998" with no debug information available, or outside of program code."
