OMAP-138 null interrupt

$

Hello,

I have a problem on a program with interruption, at some point the program enter the IRQ_handler function and is supposed to jump at the address pointed by the Global Prioritized Vector Register but the register value is 0x00000000 and according to the Global Prioritized Register their is currently no pending interruptions.

Does anyone have an idea of how this could happen ?

Best regards

Arthur
