Compiler/MSP430FR5994: Code reset problem.

Part Number:MSP430FR5994

Tool/software: TI C/C++ Compiler

Hi,

I am working on MSP430FR5994 boot-loader and application image code.

I download image in application device using BootHost and it working.

Now I am try to load application(App1) and boot image at same time using uniflash.

Both code load and run success but device reset continuously. If i remove timer interrupt from App1 code then load both(App1 and boot) code then its works and never reset.

I can not understand that what is problem?

can anyone help me?
