Two applications in parallel, freertos

Hello

my setup is a nrf52840, the sdk15.3, Softdevice s140.

is there a possibility, maybe with freertos, to to run two seperate applications like two threads.

In the blinky freertos example are a thread and timer which let leds blink. is this also possible if there there are two seperate blinky apps in the flash, one at 0x26000 and one at 0x50000 which can be handled like two threads by freertos ?

With just jumping to another applications the first is terminated so this is not a solution.

Thanks in advance for any hint....
