Issue in Interrupt priority

Hi Guys ,

I am working in cc3200 controller . I am facing some issue in interrupt priority . For example : i am using two interrupt UART interrupt and timer interrupt and i am setting UART interrupt as high priority (0x00) and timer is next priority (0x01) (Must be lower than UART interrupt) .I am continuously getting 25k Bytes to UART from other master device . The timer interrupt running every 1 sec (Its part of flow , We don t want to change it) . But issue is we are missing some data due to UART interrupt is not occur . How to solve this ??

1) I have doubt what happen if low priority (timer interrupt) is running suddenly high priority interrupt came means it will use preemptive ?.

Plz give solution as soon as possible .
