Dear All.

I am working on a CAN BUS problem and read on the internet that the solution could be to add a line of code to function :

u8 CAN_Init(CAN_InitTypeDef* CAN_InitStruct)
...
/* Wait the acknowledge */
for(WaitAck = 0x400; WaitAck > 0x0; WaitAck--)
{
}

change this to:

/* Wait the acknowledge */
for(WaitAck = 0x400; WaitAck > 0x0; WaitAck--)
{
if ((CAN->MSR & MSR_INAK) != MSR_INAK) {
break;
}
}

I have tried to change this in the stm32f10x_can.c file.

However, when i apply the change it is not reflected when i compile: e.g. i could also write rubbish in the function but it is not seen by the compiler. I have tried to make clean and then make but this does not help.
What should i do for the compiler to re-read the library?

Best regards from a newbie in ARM.
