Hello,
I am working with a LPC1768. I don't have a lot of experience with it yet, so I am stuck doing something that seems very simple - but I cannot find the reason in the manual. I am calling a function via a function pointer. Why is it then that the very first instruction of the target function
0x00000250 B510 PUSH {r4,lr}506] ; @0x1FFF0098
causes a hard fault? I am using the MSP stack, nothing fancy.
Thanks
How do you call these functions? Do you load the address explicitly, or do you allow the linker to sort things out? If explicitly, make sure the destination address is odd.

Marcus,
Thanks. I FORGOT that CM3 will only operate at Thumb-2, so I used an even address...! In the mean time I prepared an assembly work-around - no longer required. Thanks again.
