Hi Naveen,
From your mail, what i understand is you have CPU 50 GT from Motorola (Earlier Force Computers) and using VxWorks 5.4.
The error message that you are getting is related to Interrupt Vectors. Generally the Interrupt Vectors are at max of value 256 (i.e 0 to 255). Am not sure if the board supports 512 Vectors on the first hand.
You need to check the BSP Manual. Also, what part of the application code when executed results in the error message needs to be made available to give you any further inputs.
Good Luck.
Cheers,
Kiran
