Link Error : L1907: Fixup overflow in _InterruptVectorTable

Hello All,

Iam implementing a CAN Driver in CW5.1. Configured project in Processor Expert .WhenI try to assign canTransmitISR  to  vector number 0x58  as shown below

static const tIsrFunc _InterruptVectorTable[] @0xFF10U = { /* Interrupt vector table */

};

I get this Linker Error.

Link Error : L1907: Fixup overflow in _InterruptVectorTable, to  canTransmitISR  type 1, at offset 0xA0

Can anybody suggest a solution for this.

Thanks

Vijay

Hello Vijay,

First, may I suggest including the name of the derivative you are targeting in your messages ? I suspect that your issue is that you are placing canTransmitISR in a banked segment (either explicitly or implicitly by using the banked memory model). For S12/S12X the interrupt vector table contains 16-bit entries. As your routine is placed in banked memory, its address is 24-bit wide, hence it will not fit in the table entry. You should place your function in non-banked memory:

#pragma push#pragma CODE_SEG __NEAR_SEG my_near_segment/* code for canTransmitISR */#pragma pop

Also, make sure you properly place my_near_segment in the PRM file. Something like (just using my very limited memory, I don't have CW installed at this time):

PLACEMENT   my_near_segment INTO NON_BANKED;END

Hello Navidad,

Thank you for ur reply. I was out of office for a while so could'nt get back to u.

I found a solution with which it is working fine.but the problem is; i need to edit in Vectors.c when i open the project next time. It says that Vectors.c is modified and it ask whether to reload it. when I say Ok for loading theres no need to edit but it does'nt go to the ISR. Here is my implementation.:

#pragma CODE_SEG __NEAR_SEG NON_BANKED

/* code for canTransmitISR */

#pragma CODE_SEG DEFAULT 

and include  &canTransmitISR,          /* 0x58  0xFFB0   1   no   ivVcan0tx     unused by PE */ in Vectors.c

2) i tried with ur solution but it shows error as:

Error :L1009: Segment Name NON_BANKED unknown
