DSP56800E Quick Start error

[RGehring]

Hello,

I am trying to combine two of the demo programs for the 56F8013 in the Quick Start sample applications.  Specifically the SCI and ADC demo.  I updated the appconfig.h from the SCI example with the ADC information. 
With the code below when I compile it with CW8, I keep getting a error that states:

"Link Error   :  Undefined : "Frx_char_hook"  Referenced from "FSci0RxFullISR" in scibf.c"
"Link Failed."

I looked through scibf.c and rx_char_hook is in there, not really sure why it is giving the error or what it means.  It may be because I don't have the correct files or values somewhere.  But if I start from either the SCI as a base or the ADC as a base project, they both get the same error(with exactly the same appconfig.h's).

Thanks for the help!

#pragma interrupt off

[RGehring · Accepted solution]

Ok, figured it out.  In case someone has a similar problem:

Since I was enabling the rx_char_hook interrupt in the appconfig.h it needed to be used in my code, so I had to add a function like so:

UWord16 rx_char_hook(UWord16 rxchar)
{
 //asm(nop);
}

The function just has to have something in it.  And I actually realized I needed the function anyway.

I have it locked down to this part of the appconfig.h file:

#define INT_PRIORITY_LEVEL_32             INTC_LEVEL0
