Hi Henrik,

Thanks for reply. i am sorry i mean interrupt vector

i have written my own code similar to bootloader using PBP and DT-INTS. this is what happens, it first receive firmware from USB and writes it to external EEPROM, then read it and reprogram flash and jump to the new firmware (@goto). Now i think my issue is when an interrupt occurs in the new firmware it looks into bootloader interrupt vector for corresponding routine to execute, since no reference exists there it hangs/resets. if somehow i can put new interrupt vector then i think problem would be solved.
i would really appreciate any suggestions
thank you

Oh! Yeah, that's a bit of a difference....
The interrupt vectors are as far as I know something defined in the hardware of the chip itself. Location 0x0008h is the high priority interrupt vector and 0x0018h is the low priority interrupt vector. I don't see any way to change that.

Are both your bootloader AND the application using DT-INTS? I have no idea how that should/would/could work....
