i am working on ota mode like stm32 with ec200 module, inneed to run the ota mode on stm32u083mct6 by partition the flash memory when i try to run the another firmware on partition 2 by jumping to it the firmware in partition 2 is not running when i try to reset jump parttion 1 its running , what is ths issues i am facing her
